Are dinosaurs really extinct? Six little knowledge about dinosaur scientific research

CCTV News:Recently, villagers in Lufeng once again discovered dinosaur fossils. Since the first one was discovered in 1938, more than 200 relatively complete dinosaur fossils have been unearthed in Lufeng, Yunnan, spanning three periods of Jurassic. From the discovery of dinosaurs in the war-torn era to the present, many studies on dinosaur fossils have pushed China to the forefront of paleontological research. So, what’s the significance of dinosaur research? Are dinosaurs really extinct?

There were no flowers or grass in the early Jurassic world.

In 1938, the first dinosaur skeleton excavated, studied and assembled by Chinese himself — — Xu Shi Lufeng Dragon comes from Lufeng, Yunnan Province, and Lufeng is therefore known as the hometown of China’s fear of dragons. Recently, two dinosaur fossils have been found here.

According to scientists’ preliminary judgment, one of them is Lu Fenglong, with a height of about 3 meters and a weight of about 4 tons. He is about thirty or forty years old. Sex can’t be judged yet. You need dinosaur eggs or pregnant dinosaur bones to tell.

Through virtual reduction, we can see that there were no flowers and grass in the early Jurassic world, and the plants that grew were ferns that dinosaurs loved, as well as ginkgo and pine and cypress.

Dinosaurs were not extinct, but a branch of dinosaurs evolved into birds.

Are dinosaurs really extinct? Xing Lida, an associate professor at China Geo University, said that scientists found a large number of feathered dinosaur fossils in Liaoning, indicating that a branch of dinosaurs evolved into birds. In other words, dinosaurs did not die out, but flew in the sky. We can see that many behaviors of birds are very similar to those of dinosaurs.

The meaning of "social fear" in ancient times is not quite the same as today.

Dinosaurs living in the early Jurassic, food and clothing is no longer a problem, scientists believe that they have a new social pursuit.

You Hailu, a researcher at the Institute of vertebrate paleontology and Paleoanthropology, Chinese Academy of Sciences, said that from the fossils of dinosaur skulls, loong had a pair of thin "cockscomb" on his head, which may still be hollow. Obviously, it could not be used as a weapon, but as a decoration to communicate with his companions and show off himself.

In other words, dinosaurs in Jurassic period were actively socializing.

In the movie "Nothing Asked about the West", the prototype of the paleontologist is the discoverer of Lu Fenglong.

Xu Shi Lufenglong is a kind of herbivorous dinosaur that lived in the early Jurassic, and its discovery opened the prelude of dinosaur research in China.

There is such a clip in the movie "Nothing to Ask about the West": under the bombing of Japanese planes, teachers and students in The National SouthWest Associated University hid in caves to attend paleontology classes, and the prototype of the old professor was the discoverer of Lu Fenglong — — Yang Zhongjian, the founder of dinosaur fossil research in China, and this dinosaur model in class is Lu Fenglong.

In those difficult times, scientists in China did not stop exploring dinosaurs. Up to now, scientists in China have named more than 200 kinds of dinosaurs, and the ancient secrets left by those fossils are being revealed more and more. At the same time, the continuous research on these precious fossils has pushed China to the forefront of paleontological research.

What is the significance of dinosaur research?

Regarding the significance of dinosaur research, You Hailu, a researcher at the Institute of vertebrate paleontology and Paleoanthropology, Chinese Academy of Sciences, said that the past is a key to the future, and dinosaurs are only a window to study past life. But through dinosaurs, we can cross these disciplines to really let us understand the process of biological evolution, especially what the nature of life is.

Minimalist dinosaur history

Existing fossil evidence shows that early dinosaurs appeared on land about 230 million years ago.

About 200 million years ago, the earth entered the Jurassic period, and dinosaurs stood out and dominated the land.

A large number of Jurassic dinosaur fossils have been unearthed in China, such as Lufenglong, Yunnanlong, Jinshanlong and loong in the early Jurassic, Chuanjielong and Shidailong in the middle and Mamenxilong in the late Jurassic.

About 140 million years ago, the earth entered the Cretaceous period, and the species of dinosaurs reached its peak.

About 66 million years ago, there was a dinosaur extinction event. All non-bird dinosaurs were extinct in this event, and the land overlord ceased to exist.

Ministry of Transport: China’s highway infrastructure network ranks among the top in the world.

  At the press conference held by the Ministry of Transport today (25th), Wang Tai, deputy director of the Highway Bureau of the Ministry of Transport, said that since the 18th National Congress of the Communist Party of China, the scale of China’s highway infrastructure network has been among the highest in the world, and the transportation service support capacity has been continuously improved, making it easier for people to travel, which has strongly supported economic and social development and the improvement of the country’s comprehensive strength.

  The National Highway Network Plan released in 2013 proposes that by 2030, the total scale of China’s national highway network will be about 400,000 kilometers, of which the total scale of national highways and ordinary national highways will be 136,000 kilometers and 265,000 kilometers respectively. Through the efforts of all parties, by the end of 2021, 117,000 kilometers of national highways had been built, and the mileage of ordinary national highways was 257,700 kilometers, with the completion ratio reaching 85% and 96.5% respectively.

  First, the network coverage is more extensive.At present, the expressway network with the national expressway as the main body has covered 98.8% of the cities with a population of more than 200,000 and prefecture-level administrative centers, connecting about 88% of the county-level administrative regions and about 95% of the population; Ordinary national highways basically cover administrative regions at or above the county level and border ports opened all the year round, effectively connecting important towns, industrial parks, transportation hubs and tourist attractions.

  Second, the level of facilities has been effectively improved.By the end of 2021, the proportion of national highways with two-way six lanes and above will be 20.9%, and a large number of busy sections of national highways such as Beijing-Harbin, Beijing-Shanghai, Beijing-Hong Kong-Macao, Shenhai and Shanghai-Kunming will be expanded and rebuilt, and the service guarantee capacity of national highway backbone channels will be further improved. The proportion of national ordinary national highways of Grade II and above is 79.6%, which is about 10% higher than that in 2013. More than 98% of the roads have been paved with asphalt or cement concrete, which is about 13% higher than that in 2013.

  Third, major projects continued to advance.The world-famous Hong Kong-Zhuhai-Macao Bridge was opened in October 2018, becoming a super cross-sea project integrating bridges, islands and tunnels. The Beijing-Xinjiang Expressway, which passes through the desert Gobi no man’s land, runs through the whole line, becoming another big passage in and out of Xinjiang after Lianhuo Expressway. Construction of Tianshan Shengli Tunnel on Urumqi-Yuli Expressway, which is more than 22 kilometers, started, constantly setting a new world record for expressway tunnels.

  The fourth is to achieve breakthroughs in technological innovation.The highway survey and design technology represented by digital map, geological remote sensing, computer-aided design and simulation, and Beidou system application has made continuous progress. The technology of highway construction in soft soil, loess, frozen soil and desert areas is constantly maturing and improving, and the structure and material technology of highway pavement have withstood the double test of time and heavy traffic. Breakthroughs have been made in technologies and equipment related to super-long-span bridges, super-long tunnels in mountainous areas, submarine immersed tunnels and large-diameter shield tunnels, and "China Road, China Bridge and China Tunnel" have become beautiful business cards.

Is this vaccine effective for everyone? Once and for all after vaccination?

  CCTV News:On May 30, the highly concerned HPV nine-valent vaccine (nine-valent cervical cancer vaccine) began to be injected in Boao, Hainan. On the first day of injection, about 1,000 people completed the vaccine appointment.

  HPV vaccination should be treated rationally

  A month ago (April 29th), National Medical Products Administration approved the marketing of nine-valent cervical cancer vaccine in the Mainland. Boao Lecheng International Medical Tourism Pioneer Zone enjoys nine supporting policies, such as drug import registration and approval, and it takes only one month to take the lead in completing all the approval of nine-valent cervical cancer vaccine for marketing injection, and injecting it for school-age women in need. According to the regulations,The vaccine in the Mainland is suitable for women aged 16 to 26.

  It is understood that HPV nine-valent vaccine is the most comprehensive vaccine against HPV virus in the world, and it can prevent 90% of cervical cancer against nine subtypes. It can be injected in Hong Kong earlier, and a shot costs about HK$ 2,250.

  Experts from National Medical Products Administration, Health and Health Commission and China CDC have recently answered questions related to vaccines.Experts said that HPV vaccination should be treated rationally.(For details, see: the vaccine that can prevent more than 90% of cervical cancer can be listed in China conditionally.)

  Nine-valent HPV vaccine "conditionally approved for marketing"

  Experts pointed out that at present, the nine-valent HPV vaccine that has been approved for import registration by priority review is conditionally approved for marketing. Shao Jie, reviewer of the Clinical Department of Biological Products of the National Drug Administration Center, said that conditional approval paid attention to the ethnic differences of clinical trial subjects.

  Data from overseas clinical trials show that,There are more than 2,000 Asian people in the clinical trial of the nine-valent HPV vaccine.China, Hongkong, China, Taiwan Province, Japan, Korea, etc. The population of China, Hongkong and Taiwan Province, China, which were included in the clinical trial, were analyzed separately, and the results were consistent with those of the global population. This is the basis for the inclusion of imported nine-valent HPV vaccine in conditional approval.

  Experts said that the overall principle of conditional approval is that the benefits outweigh the risks. After the enterprise is conditionally approved, it needs to improve the follow-up research work as required, and the regulatory agency will continue to follow up and supervise the vaccine throughout its life cycle.

  The age range of vaccination adaptation is 16 ~26 years old.

  The nine-valent HPV vaccine approved for marketing in ChinaThe age range of vaccination adaptation is 16 ~26 years old.. The reason why it is designated as this age group comes from three aspects:

  1. At this age, the overseas clinical research data of the vaccine and its protective effect against persistent infection in East Asian population all suggest that the benefits outweigh the risks.

  Second, the probability of sexual behavior among girls aged 9-15 in China is very low. However, the 9-to 15-year-old vaccinators only carried out the immune bridging test, and the clinical research data of the East Asian Chinese population in this test were limited.

  Third, women over the age of 26 may have a history of virus exposure and infection. At present, there is no evidence to prove that this vaccine has a protective effect on the exposed population of this age group.

  In addition, experts said that,The incidence of adverse reactions of nine-valent HPV vaccine will be higher than that of four-valent vaccine.

  Wang Huaqing, chief expert of immunization program of China CDC, pointed out that vaccination is primary prevention and screening is secondary prevention, which are equally important at present.Cervical cancer screening measures should not be relaxed because of vaccination.

  What are the differences between bivalent, tetravalent and ninth-order vaccines used to prevent cervical cancer? A picture makes it clear ↓

In the flu season, Jiangsu CDC suggested timely vaccination against influenza.

Since September, Nanjing Children’s Hospital has received nearly 400 cases of influenza, which ushered in a small peak of influenza treatment.

Recently, the National Health and Wellness Commission held a press conference, suggesting that with the cold weather, it is the epidemic season of respiratory infectious diseases. Wang Huaqing, chief expert of immunization program of China CDC, suggested that influenza vaccine should be vaccinated before the end of October.

He mentioned that vaccination is usually better before the flu epidemic season, and it is generally recommended to complete vaccination before the end of October. If the vaccination is not available before October for various reasons, the vaccination should be completed as soon as possible in the follow-up so that the effect of the vaccine can be better played. Because it takes about 2 to 4 weeks for the vaccine to have an effect.

How to choose the flu vaccine? Who should be vaccinated the most? Who doesn’t recommend vaccination? About 13 questions about influenza vaccine, Jiangsu CDC authorities answered questions-

Q1. Why should I get the flu vaccine?

Influenza is not a common cold, but an acute respiratory infection caused by influenza virus. According to the estimation of the World Health Organization, influenza can cause 3 million to 5 million severe cases and 290,000 to 650,000 respiratory diseases-related deaths worldwide every year. Vaccination against influenza is an effective means to prevent influenza and reduce influenza-related severe illness and death.

Q2. What are the types of influenza vaccines? How should I choose?

There are inactivated vaccines (including split vaccines and subunit vaccines), attenuated live vaccines and recombination vaccines. According to the components contained in the vaccine, it can be divided into trivalent and tetravalent influenza vaccines. Compared with trivalent influenza vaccine, tetravalent influenza vaccine strains have added a pedigree of influenza B. Inactivated vaccine was injected intramuscularly, and attenuated live vaccine was sprayed intranasally.

The influenza vaccines approved for marketing in China this year include trivalent inactivated vaccine, tetravalent inactivated vaccine and trivalent attenuated live vaccine. People aged ≥6 months can be vaccinated with trivalent or tetravalent inactivated vaccine, and people aged 3~17 can also choose trivalent attenuated live vaccine. For people who can be vaccinated with different types of vaccine products from different manufacturers, they can voluntarily vaccinate any kind of influenza vaccine, and there is no priority recommendation.

Q3. When should I get the flu vaccine?

Usually, the antibody can reach the protective level after 2~4 weeks of influenza vaccination. The time and duration of the annual peak of influenza activity are different in different parts of China. It is suggested that the recipients should be vaccinated with influenza vaccine one month before the influenza epidemic season. If the vaccination is not completed before the arrival of the epidemic season, it can be vaccinated throughout the epidemic season.

Q4. Where can I get the flu vaccine?

Influenza vaccines can usually be vaccinated in community health service centers or hospitals. Vaccination units may vary from place to place, so please consult the local health administrative department for details.

Q5. Who needs influenza vaccination?

People who are over 6 months old and have no vaccination contraindications should be vaccinated against influenza.

Combined with the epidemic situation of influenza and the prevention and control strategy of multi-disease prevention, the harm of influenza is reduced as much as possible, and the following key and high-risk groups are recommended to be vaccinated in time:

① Medical personnel, including clinical rescue personnel, public health personnel, health and quarantine personnel, etc.

② Older people over 60 years old;

③ people suffering from one or more chronic diseases;

(4) Vulnerable people and employees in gathering places such as old-age care institutions, long-term care institutions and welfare homes;

⑤ Children aged 6 ~ 59 months;

⑥ Family members and caregivers of infants under 6 months old;

⑦ Crowds in key places such as kindergartens, primary and secondary schools and supervision places.

Q6. Who can’t be vaccinated?

① Those who are allergic to any ingredients contained in the vaccine (including auxiliary materials, formaldehyde, cracking agents and antibiotics) or who have had a history of severe allergy to any kind of influenza vaccination are prohibited from vaccination;

② Patients suffering from acute diseases, severe chronic diseases or acute attacks of chronic diseases, as well as patients with fever, are advised to be vaccinated after recovery or stable control of their condition;

③ Patients with Guillain-Barre syndrome within 6 weeks after previous influenza vaccination are advised to be evaluated by doctors before considering whether to vaccinate.

It should be noted that the following populations are prohibited from receiving live attenuated vaccines:

① Persons with low immune function due to drug use, HIV infection and other reasons;

② Children and adolescents who have been treated with drugs containing aspirin or salicylic acid for a long time;

③ Children with asthma aged 2-4 years;

4 pregnant women;

⑤ Those with a history of Guillain-Barre syndrome;

⑥ Those who used antiviral drugs such as oseltamivir and zanamivir 48 hours before inoculation, or those who used palamivir 5 days before inoculation, or those who used balosevir 17 days before inoculation.

Q7. What should I pay attention to after influenza vaccination?

After vaccination, you need to stay in the vaccination unit for half an hour. If there is no abnormality, you can leave on your own. After returning home, pay attention to rest, eat lightly and avoid strenuous exercise. If there is any abnormal phenomenon, you can consult and report to the vaccination doctor and go to the hospital if necessary.

Q8. Why do you have to get the flu vaccine every year?

First of all, influenza virus is prone to mutation. The World Health Organization proposes the recommended components of influenza vaccine for the next epidemic season every year based on the results of global influenza surveillance, and the influenza virus strains targeted by influenza vaccines may be different in different years. Secondly, the immunity of influenza vaccination will gradually weaken over time. Therefore, in order to provide more effective protection, it is recommended to vaccinate against influenza every year.

Q9. Is it safe to get the flu vaccine? Are there any side effects?

Influenza vaccination is safe, but like other medical products, influenza vaccine may also have adverse reactions. The common adverse reactions of influenza vaccination include local reactions (redness, swelling, induration, pain, burning sensation, etc.) and systemic reactions (fever, headache, dizziness, lethargy, fatigue, myalgia, general malaise, nausea, vomiting, abdominal pain, diarrhea, etc.). These adverse reactions are usually mild, and usually disappear on their own within a few days, with few serious reactions.

Q10. Can people with egg allergy be vaccinated against influenza?

Egg allergy is not a taboo in People’s Republic of China (PRC) Pharmacopoeia (2015 and 2020 editions). The current pharmacopoeia stipulates that the content of ovalbumin in inactivated influenza virus vaccine should not be higher than 250ng/ dose, and the content of ovalbumin in split vaccine should not be higher than 200ng/ml. There is no description of attenuated live vaccine at present. The measurement of egg protein content in commonly used influenza vaccines in China shows that the highest content is not more than 140ng/ml. At the same time, foreign scholars’ research on the inactivated vaccine or attenuated live vaccine inoculated to those who are allergic to eggs shows that no serious allergic reaction has occurred. Therefore, egg allergy is not recommended as a taboo for influenza vaccination.

Q11. Won’t you get the flu after vaccination?

In most years, influenza vaccine has a good match with influenza epidemic strains and has good protection. However, there is also a certain probability that the strain of influenza vaccine does not match the epidemic strain, which further affects the protection effect of influenza vaccine. In addition, influenza vaccination can only prevent influenza caused by influenza virus, but can not prevent such symptoms caused by infection of pathogens other than influenza virus (such as parainfluenza virus, adenovirus, etc.).

Q12. Can I get the flu vaccine while using antiviral drugs?

Inactivated influenza vaccine can also be inoculated during the prevention and treatment of influenza antiviral drugs. Preventive or therapeutic use of anti-influenza drugs will affect the immune effect of attenuated live influenza vaccine, and it is not recommended to use both at the same time. If you have used any other vaccines or drugs, including over-the-counter drugs, please inform the vaccination doctor before vaccination.

Q13. Can the flu vaccine be vaccinated at the same time as other vaccines?

Inactivated influenza vaccine, other inactivated vaccines and attenuated live vaccines, such as enterovirus 71 vaccine, pneumococcal vaccine, herpes zoster vaccine, chickenpox vaccine, measles vaccine and DTP vaccine, can be inoculated in different parts at the same time.

There is limited research evidence that live attenuated influenza vaccine and other vaccines are vaccinated at the same time. After vaccination with live attenuated influenza vaccine, other live attenuated vaccines can only be vaccinated after an interval of more than 4 weeks. (Wang Tian)

On behalf of the Shanghai Municipal Party Committee, the Municipal People’s Congress, the Municipal Government and the CPPCC, Han Zheng congratulated the advanced collectives and individuals who were commended for their meritorious deeds in key projects, paid tribute to the vast number of urban builders and managers who fought in the front line all the year round, and expressed gratitude to the general public who understood, cared for and supported urban construction and major projects. He said that at this time of the year, we review the course of Shanghai’s key projects’ practical meritorious deeds competition, feel the hardships and share the joy of success. Since China’s reform and opening-up, especially since Pudong’s development and opening-up, Shanghai’s key projects have been closely focused on making up the shortcomings and facing the future development, constantly pushing forward, laying a solid foundation for the city’s economic and social development. This year is the year of deepening the 13th Five-Year Plan. According to the requirements of the central authorities, Shanghai is striving to be the vanguard of national reform and opening up and the pioneer of innovation and development, and is striving to basically build the "four centers" and a socialist modern international metropolis by 2020. The field of urban construction shoulders heavy responsibilities. Hope that advanced collectives and individualsAlways adhere to safety first, quality first, safety is the bottom line, and quality is life. We must always tighten the string of safety and continue to play a benchmark and leading role in key projects and practical projects with the world’s advanced level as the standard. Always adhere to management as the priority and science and technology as the guide, put management in a more important position to ensure safety and quality, highlight scientific and technological innovation, and improve the quality of the city. Always adhere to the people-friendly and civilized construction, and try to minimize the impact on the orderly operation of the city and the normal life of the citizens during the construction process.

At the commendation meeting, Yang Xiong said that last year, the achievements of major projects and practical projects in this city were gratifying, the shortcomings of urban management were remarkable, and the task of aiding Xinjiang was successfully completed, achieving the "Thirteenth Five-Year Plan" and "a good start". This year is an important year for implementing the 13th Five-Year Plan and deepening the structural reform on the supply side. Facing the new situation, we should conscientiously implement the general tone of striving for progress while maintaining stability, sum up experience, blaze new trails, roll up our sleeves and go all out to complete various construction tasks.

"Safety and quality are the lifeline of major engineering construction and must always be put in the first place." Yang Xiong pointed out that it is necessary to pay strict attention to construction safety, take effective measures, consolidate the main safety responsibilities of construction, survey, design, construction and supervision, pay close attention to key construction links, and strengthen the safety control of major risk sources. It is necessary to continuously improve the quality of the project, adhere to the international first-class benchmarking, comprehensively consider the design, construction and operation, adopt more advanced international quality standards, vigorously carry forward the craftsman spirit, and strive to create more excellent projects. To improve the level of civilized construction, the construction unit should further strengthen the overall awareness, focus on improving internal management, reduce related social costs, and minimize the impact of engineering construction on the city. The construction of rail transit stations should strive to occupy less roads and return them early. It is necessary to strengthen dust control on construction sites and roads, and urge transportation enterprises to reduce "leakage" in muck transportation. We should persist in scientific and technological innovation and promote the transformation and upgrading of the construction industry. To become an important carrier of scientific and technological innovation, major projects should promote prefabricated buildings in major projects throughout the city, and constantly increase the proportion of prefabricated components used in each project. It is necessary to speed up the popularization of building information model technology (BIM), and establish and improve the matching project approval mode and standard system. It is necessary to make more use of new technologies such as the Internet of Things and big data to explore intelligent life cycle management of buildings.

Shanghai leaders Ying Yong and Xue Chao, and Yi Li Pinghe Garrison leader Ma Jiali attended the meeting. A number of advanced collectives and individuals who made outstanding contributions to the construction of major projects and practical projects in this city in 2016 were commended.

It is reported that in 2016, 122 major engineering projects in the city were comprehensively promoted. By the end of December of that year, a total investment of 128.01 billion yuan had been completed, and 123.6% of the plan was completed at the beginning of the year.

Global News: Is the American Banking Crisis Back? Risk aversion rose sharply, and US stocks closed down across the board.

  On Tuesday, local time, US stocks finally got rid of the light market trend for more than a week, but unfortunately it was not a big rise but a big drop. The three major indexes closed down across the board, with the Dow down more than 300 points and the Nasdaq down 2%.

  On the one hand, the power of the earnings season began to show, and giants such as McDonald’s and UPS warned that the macroeconomic prospects were not good in the earnings report. On the other hand, the deposits of Daiwa Bank in the United States dropped by 40%, and UBS’s net profit in the first quarter halved, all of which highlighted that the banking crisis had not completely subsided and the market risk aversion was ignited.

  On Monday, the First Total Bank disclosed that even though Wall Street giants had jointly deposited 30 billion dollars, they lost over 70 billion dollars in the first quarter of this year alone. At the end of the first quarter, the deposit figure was only $104.5 billion, far below the $136.6 billion expected by analysts.

  The first total and the bank lost 49.38% of its market value on Tuesday. In the news, the media reported that the bank was going to sell "50 billion to 100 billion dollars" of long-term assets to solve the mismatch problem. It is reported that Biden administration officials have been keeping in touch with Daikyo Bank in recent days, and the White House is increasingly worried that there is not much time left for Daikyo Bank to appease investors and depositors, but American policy makers are not worried that risks may spread further among banks.

  It is worth noting that due to various indications that there are still many risk factors in the market, traders no longer bet 100% that the Fed will continue to raise interest rates before the middle of this year. According to the observation tool of the Federal Reserve, the probability of raising interest rates by 25 basis points in May fell to 81.5%, compared with 90.5% the previous day.

  However, for technology stocks, the financial reports of Microsoft and Google have slightly eased some market concerns. AI and cloud services helped Microsoft’s financial report exceed expectations, with revenue of $52.9 billion, higher than analysts’ expectations of $51.03 billion; Earnings per share were $2.45, higher than analysts’ expectations of $2.24. More importantly, a strong profit guidance was released, which rose by 8% after hours.

  Google’s parent company Alphabet’s revenue in the first quarter was $69.79 billion, higher than analysts’ expectations of $68.99 billion. Earnings per share was $1.17, higher than analysts’ expectations of $1.09. At the same time, it was announced that the board of directors authorized an additional repurchase of up to $70 billion. Google rose more than 4% after hours.

  In addition, OpenAI plans to launch a new product, ChatGPT Business, which is the enterprise version in the next few months. At the same time, the new function of ChatGPT allows all users to turn off chat records, which will not be used to train and improve the model of OpenAI.

  In terms of important macro news, according to Xinhua News Agency, US President and Democrat Biden officially announced his re-election as US President on the 25th. Biden released a video on the same day to officially announce his decision to run for re-election as president of the United States, and pointed his finger at the so-called Republican extremist forces, saying that the United States is still in the struggle of "fighting for the soul of the country" and he needs more time to "complete this work."

  This means that next year, the world may once again witness the "peak confrontation" between Trump and Biden.

  Biden officially announced his re-election as president of the United States.

  According to Xinhua News Agency, U.S. President and Democrat Joe Biden officially announced his re-election campaign on the 25th. Biden released a video on the same day to officially announce his decision to run for re-election as president of the United States, and pointed his finger at the so-called Republican extremist forces, saying that the United States is still in the struggle of "fighting for the soul of the country" and he needs more time to "complete this work."

  Biden is 80 years old. In the 2020 US presidential election, he defeated Trump, the then US president and Republican, and became the US president in January 2021.

  Banking crisis worries have re-suppressed the market’s interest rate hike pricing for the Fed.

  The interest rate swap contract of the Federal Reserve in June currently reflects that the benchmark interest rate of the central bank is only 20 basis points higher than the current effective federal funds rate, which implies that the possibility of raising interest rates in one of the next two FOMC meetings is about 80%, while it was almost certain that the Fed would raise interest rates in May.

  The debt ceiling deadlock is hard to solve. The White House says Biden will veto the Republican bundled spending reduction plan.

  The Republican proposal put forward by House Speaker McCarthy requires that the debt ceiling of $1.5 trillion be raised and the future total government expenditure be reduced by $4.5 trillion. On Tuesday, the White House said that the debt ceiling must be solved without any conditions. Also on Tuesday, US Treasury Secretary Yellen warned lawmakers that if the debt ceiling is not resolved, the economic achievements made in the past two years will be threatened.

  As the inflation rate exceeded 100% for the first time in 30 years, and the record drought dealt a heavy blow to agriculture-related industries, Argentina’s economic activity remained stagnant in February, with GDP increasing by 0% month-on-month and only 0.2% year-on-year. But high inflation does not seem to cool down in a short time. Argentina’s central bank predicts that the country’s inflation rate will reach 110% in 2023.

Four Questions about Vaccination for the Elderly —— An investigation report from the front line of epidemic prevention and control

  Xinhua News Agency, Beijing, December 18th: Four Questions about Vaccination for the Elderly — — Investigation report from the front line of epidemic prevention and control

  Xinhua news agency reporter

  90.37%, which is the proportion of people who have completed the whole vaccination of Covid-19 vaccine in China; 86.6% and 66.4%, respectively, are the proportion of people over 60 years old and over 80 years old who have completed the whole vaccination.

  With the weakening of pathogenicity in Omicron, the popularization of vaccination and the accumulation of prevention and control experience, China’s epidemic prevention and control is facing a new situation and new task.

  The comprehensive group of joint prevention and control mechanism in the State Council optimized the implementation of the "New Ten Articles" of epidemic prevention and control, and accelerated the Covid-19 vaccination for the elderly. The Central Economic Work Conference just held also proposed that we should optimize epidemic prevention and control measures according to the current situation, conscientiously implement various measures for epidemic prevention and control in the new stage, focus on the prevention and control of the elderly and groups suffering from basic diseases, and strive to maintain health and prevent severe diseases.

  Why should we emphasize the necessity of vaccination for the elderly? Does vaccination work? Is vaccination safe? The reporter launched an investigation on the front line of epidemic prevention and control.

  On December 15th, at the COVID-19 Vaccination Point in Zhongguancun Street, Haidian District, Beijing, medical staff vaccinated the elderly with COVID-19 vaccine. Xinhua News Agency reporter Ren Chaoshe

  How necessary — — The defense line of the elderly group is relatively fragile.

  Li Cuiwen, 78, lives in a remote village in the central province. Children are all in the city. On weekdays, they send rice flour oil, and the vegetables are grown in their own fields. They go to the town to catch a gathering once a month.

  "I can’t see outsiders." Li Cuiwen and his wife have not been vaccinated with Covid-19 vaccine so far. "Is everyone fighting, even if we don’t fight, we can’t infect us?"

  Li Cuiwen is not the only one who has similar questions. In this regard, Xia Gang, director of the Department of Health and Immunity of the National Bureau for Disease Control and Prevention, said that there are quite a few disabled and semi-disabled people in China who live at home for a long time and rarely go out, but they may still be infected when they are accompanied by relatives or visited by relatives.

  Compared with the previous strains in Covid-19, the pathogenicity of Omicron is weakening, but the infectivity is becoming stronger. The extremely fast transmission speed is multiplied by China’s huge population base. Even if the severe illness rate and mortality rate are already very low, the number of people at risk should not be underestimated.

  During the epidemic in Shanghai from March to June this year, compared with those who were not vaccinated, the death risk of people over 60 years old who completed the booster immunization was reduced by 98.08%, and that of people over 80 years old who completed the booster immunization was reduced by 95.83%.

  At the press conference of the State Council Joint Prevention and Control Mechanism held recently, Xia Gang introduced that according to the research, if the elderly over 80 years old are not vaccinated with one dose of vaccine, the risk of death after being infected with Covid-19 is about 14.7%; If one dose of vaccine is inoculated, the risk of death will be reduced to 7.16%; If three doses of vaccine are inoculated, the risk of death will be reduced to 1.5%.

  "I strongly call for accelerating the vaccination of vaccines, especially for vulnerable people such as the elderly." Zhong Nanshan, an academician of China Academy of Engineering, said.

  On December 15th, two groups of communities were prepared in Kangmei Street, Liangjiang New District, Chongqing, and the medical staff of the community health service center checked the information of the elderly who had been vaccinated with COVID-19 vaccine. Xinhua News Agency reporter Huang Weishe

  How effective is it — — Survey data show that the risk of severe illness can be greatly reduced.

  In Chongqing, Zhang, an 84-year-old rehabilitation patient, told reporters that he suffered from many basic diseases such as hypertension and diabetes. He completed the third dose of vaccination in July this year and was infected with Covid-19 in November. After treatment, his condition was effectively controlled and he has been discharged.

  On December 16th, in the home of residents in Honghe Road Community, Zhongshan Road Street, Yongchuan District, Chongqing, the mobile vaccination team conducted pre-vaccination consultation and physical examination for the vaccinated elderly. Xinhua News Agency reporter Huang Weishe

  "Studies at home and abroad confirm that vaccination has a good effect in preventing serious illness and death." Xia Gang said that after being infected with Covid-19, the elderly are more likely to develop into severe illness or even death, and Covid-19 vaccine will benefit the most.

  At most, beijing ditan hospital has treated more than 100 COVID-19 patients over 80 years old. Chen Xiaoyou, vice president of the hospital, said that the vaccination rate of these elderly patients is generally low, and the incidence of severe illness after illness is relatively high, especially in COVID-19, which is aggravated by basic diseases.

  COVID-19 Designated Treatment Hospital in Hefei — — Ding Zhen, director of the Department of Respiratory and Critical Care Medicine of Hefei Binhu Hospital, told the reporter: "For some elderly people with basic diseases such as hypertension and diabetes, Covid-19 infection may aggravate the inflammatory reaction in the body, aggravate the condition of the basic diseases, and even lead to multiple organ failure."

  Ding Zhen introduced that from the observation of their clinical treatment, the elderly who have been vaccinated are less likely to get worse and the time required for nucleic acid to turn negative is shorter.

  In October, 2022, The Lancet Infectious Diseases published a research result based on the real-world vaccination population, which was released by the relevant research team of School of Public Health, Li Ka-shing Medical College, HKU. The study shows that the effective rate of preventing severe illness is about 70% for the elderly over 60 years old who are vaccinated with two injections of domestic inactivated vaccine, and the effective rate of preventing severe illness is over 95% after the third injection of intensive immunization.

  On December 13th, in the Community Health Service Center of Baihedong Street, Liwan District, Guangzhou, medical staff made information entry and consultation for the elderly residents who came to receive COVID-19 vaccine. Xinhua News Agency reporter Deng Hua photo

  Security geometry — — Make clear the taboo of vaccination and ensure safety to the greatest extent.

  In the past few days, in Huanghuagang Street, Yuexiu District, Guangzhou, the average number of elderly people who take the initiative to consult and make an appointment for vaccination has exceeded 300, which is significantly higher than usual.

  Yu Shu and Ye Yi, who live in Nongben community, had concerns about vaccination because of their basic diseases. After many door-to-door publicity by community workers and volunteers, Ye Yi was vaccinated under the health monitoring of doctors, and there were no adverse reactions. The next day, Uncle Yu also completed the vaccination. "Now I know that the previous concerns are redundant."

  On December 12th, in Guanggang New Town, Liwan District, Guangzhou, elderly residents got off the convenient vaccination vehicle after receiving COVID-19 vaccine. Xinhua News Agency reporter Deng Hua photo

  The reporter found in many places that the enthusiasm of the elderly for vaccination has improved significantly recently, but some elderly people are still worried about the safety of vaccines. Many elderly people admitted to reporters that they were mainly worried that "they are old and have basic diseases, which will bring adverse reactions after vaccination".

  "Chronic diseases such as diabetes and hypertension are not absolute taboos for vaccination in Covid-19. As long as these chronic diseases are well controlled and in a stable period, Covid-19 vaccine can be vaccinated." Zheng Zhongwei, director of the Science and Technology Development Center of the National Health and Wellness Commission and head of the working group of the vaccine research and development special class of the the State Council Joint Prevention and Control Mechanism, said.

  According to the situation of vaccine research and development and the practice of vaccination, the joint prevention and control mechanism of the State Council has defined the vaccination taboos of the elderly in the Work Plan for Strengthening Covid-19 Vaccination for the Elderly, including four types of situations in which vaccination cannot be carried out or postponed. At the same time, local health departments should implement the "four haves" requirement that vaccination units should have emergency personnel stationed in general hospitals with level 2 or above, emergency equipment and medicines, 120 ambulances on duty, and green channels for treatment in general hospitals with level 2 or above to ensure vaccination safety.

  Step by step to carry out training on judging vaccination contraindications, and guide medical staff to scientifically judge vaccination contraindications; Well-known doctors from various specialties were transferred to form a vaccination consultation expert group to patiently answer various consultation questions … … Many places are refining the work of answering questions and doubts to eliminate the doubts of vaccination for the elderly to the greatest extent.

  How convenient is it — — The "last 100 meters" is constantly getting through.

  Every Tuesday and Saturday afternoon, it is the day when the "Medical Qingqi Team" comes to the door for vaccination in Pingguoyuan Street, Shijingshan District, Beijing. The "Medical Qingqi Team" consists of 5 to 6 street, community workers and medical staff, and is divided into two groups, each group can enter about 12 households.

  "Conduct a health assessment first, ask the elderly whether they have basic diseases, look at past medical history, etc., and confirm whether the elderly are suitable for vaccination." Luo Yan, one of the medical staff of the "Medical Qingqi Team" and the medical department of Beijing Rehabilitation Hospital affiliated to Capital Medical University, said, "After the assessment, we will further communicate with our family members, and after the family members agree, they will sign an informed consent form and vaccinate."

  Similar situations have appeared in many places recently. A special session of Covid-19 vaccination was held in Jinbi Yayuan Community, Baiyun District, Guangzhou. 63-year-old Ms. Liu suffers from rheumatoid arthritis. The medical staff inquired about her physical indicators in detail. After assessing that she met the vaccination requirements, she was instructed to take the third shot of vaccine.

  On December 10th, He Lingling (left), a nurse from Fangmiao Street Community Health Service Center, vaccinated the elderly in the community with COVID-19 vaccine at COVID-19 vaccination site in Yaohai District, Hefei. Xinhua News Agency reporter Guo Chenshe

  Li Zizhen, director of the immunization room of the Community Health Service Center of Dongcheng Sub-district Office in jieshou city, Anhui Province, told the reporter that twenty or thirty elderly people have come to get Covid-19 vaccine every day recently, and the telephone number for consultation is also from morning till night. A mobile door-to-door vaccination service team was set up in the local area, equipped with first-aid equipment and medicines, and came to the door at any time.

  Set up green channels for the elderly, temporary inoculation points and mobile inoculation vehicles; Medical staff with rich experience in diagnosis, treatment and vaccination are selected to form vaccination teams, carrying common equipment and medicines needed during post-vaccination observation, and providing home vaccination services for disabled and semi-disabled elderly people … … Many places are optimizing various convenience measures as required, and getting through the "last 100 meters" for the elderly.

  For the country’s 267 million elderly people over the age of 60, every 1 percentage point increase in vaccination rate means that more than 2 million people have built a barrier against serious illness and death. "The Spring Festival is coming, and now vaccination usually takes half a month to be effective, which is of great benefit to prevent large-scale spread when people go home and a large number of people migrate during the Spring Festival in Spring Festival travel rush." Zhong Nanshan said.

A fine rice variety is bred in this way (first-line investigation)

  Source: Ministry of Agriculture and Rural Affairs, etc.

  In April 2022, General Secretary of the Supreme Leader visited Hainan and came to the "brain" of Nanfan Scientific and Research Breeding Base — — Sanya yazhouwan seed laboratory. The general secretary said: "Only by grasping the seeds of China with your own hands can you stabilize China’s rice bowl and achieve food security."

  Nanfan, a large number of agricultural workers’ repeated migration journey. From September every year to May the following year, they come to Hainan from all over the world to take advantage of the unique tropical climate conditions here to carry out a series of scientific research activities such as crop seed breeding, hence the name "Southern Breeding".

  At the moment, it is the season of the south. Let’s follow a rice seed to observe how it will grow from creating materials to breeding and seed production.

  Sampling — — Sanya, Hainan

  It took 10 years to produce a good variety.

  Some have just been sown or seedlings, some are heading green, and some are golden to be harvested — — Walking into the Nanfan Base in Sanya, Zhongzhong Group, you can get a glimpse of rice at all growth stages.

  "The advantage of Hainan is that there are abundant light and temperature resources, and we will sow here every one or two months." Shi Yitao, assistant of rice breeding in Zhongzhong Group, is a good way in the crop field. "Farmers will, we will;" Farmers won’t, and we understand. "

  For a year, he guarded the experimental field like a child, and his broad face was tanned. "Water carefully every day to observe, prevent snails, birds and mice. I want every seedling to sprout and thrive. " Shi Yitao said.

  It’s windy, rainy and sunny, which is a summary of the local climate by Nanfan people.

  Sowing in the hot sun, sometimes, you have to hide from the rain four or five times for half a day. Whenever it rains, Shi Yitao is on tenterhooks: when the seedlings were young, he was afraid of the heavy rain and washed up the nutrient soil and washed away the seedlings; The rice is a little longer, catching up with the typhoon. The water in the field is more than 60 centimeters, leaving an ear on the water surface. It is raining against the wind and drowning again and again. "Danger is not afraid, and nothing is important to keep the seedlings."

  In the corner of the experimental field, the iron fence was deeply embedded in the soil, and a small rice field was specially taken care of. "Specially rat-proof, afraid of gnawing materials." Shi Yitao gently pulled open the iron door and walked through a ridge, and the green and tall seedlings came into view.

  "these are breeding materials R1607 with low cadmium gene introduced, which is already in tillering stage." Shi Yitao bowed down and took off a piece of leaf with tweezers, about 1 cm long, and carefully put it in a deep hole plate. "I hope it will be successful in one sampling."

  From the summer of 2021 to now, this batch of materials has been planted in Hainan for three consecutive seasons, plus one season in Hainan in winter of 2020 and one season in Hubei in early 2021. It has been crossing, backcrossing and selfing for more than two years, and it has been five generations. Preliminary laboratory data show that the genetic traits of low cadmium gene have already appeared in future generations.

  "If there is no problem with the re-inspection data, after maturity, you can select a trial plant with the best growth and the best laboratory genetic data from these 2000 strains." Shi Yitao said.

  Just pick one plant, will it be too few?

  "You don’t look down upon it, the seed setting rate is very high, one plant also has one or two thousand grains, and the ear of rice is half an arm long. This is also the reason why the rice variety Youyou 607 is favored by the market. "

  "If you compare Quanyou 607 to an excellent ‘ Baby ’ Then R1607 is like an excellent ‘ Father ’ 。” Zhou Hua, director of rice testing of Zhongzhong Group, said that R1607 not only aggregated 8 rice blast resistance genes and 3 lodging resistance genes, but also aggregated 17 genes of sheath blight resistance, cold tolerance, flood tolerance, nitrogen efficiency and yield. Now, after introducing the low cadmium gene, even if rice is planted in fields with excessive cadmium content, it is low in adsorption or insensitive to cadmium.

  How long does it take to breed a fine variety like Quanyou 607?

  "It took 10 years from breeding to variety approval!" Zheng Ruifeng, the head of the R&D team of Quanyou 607 and the director of rice breeding of Zhongzhong Group, said that the creation of new materials is very uncertain. "There have been 52 cross combinations, and finally only R1607 was bred."

  The R&D team will then introduce genes against bacterial blight, rice planthopper and fragrance, etc., and constantly upgrade and transform R1607 to become an all-around champion, so that the "baby" born will be better.

  What is the most difficult thing in breeding?

  Zheng Ruifeng replied in this way: if the varieties that show "leverage" are planted in other places for trial planting, some unexpected situations may occur, such as not resisting high temperature, low temperature, lodging, a certain disease, or a certain climate. Sensitive, "this will make all previous efforts and investments zero."

  The early research and development is difficult, but the heart is still not hanging. Once it enters large-scale production, the strings in the heart will be tightly stretched. The bigger the promotion area, the more worried it is. "If farmers fail to harvest food, we will have trouble sleeping, and we will be relieved when we harvest it." Zheng Ruifeng said.

  Detection — — Wuhan, Hubei

  Breeding experts wear "gene glasses"

  In Wuhan, Hubei Province, the genotyping laboratory of the Life Science and Technology Center of China Seed Group, the low cadmium sample sent from Sanya base, finally ushered in the key experimental link — — DNA genetic material was extracted and analyzed.

  Zhang Xiaobo, the head of the laboratory, tapped the button, and the shaker, centrifuge and PCR instrument ran one after another. The data showed that the recovery rate of differential loci was 88.7%, and the recovery rate of whole genome reached 97.5%.

  What do these data mean? "This shows that the low cadmium gene has indeed been stably passed on to the offspring of R1607. After the upgraded version of R1607 matures, a new trial production process can be started." Zhang Xiaobo explained.

  "In the breeding process, the laboratory and the experimental field are closely linked." Ye Rongjian, deputy director of the Technology Platform Department of the Science and Technology Center of Zhongzhong Group, said that the genetic performance after the introduction of low cadmium gene is difficult to observe by experience. "Is cadmium adsorbed into rice seeds? The naked eye can’t see it at all."

  "When R1607 was first created, molecular biological breeding technology was just beginning, and we took the path of traditional cross breeding combined with molecular breeding assisted selection. Nowadays, molecular marker detection and genome breeding technology have become very common, which is like wearing a pair of glasses that can see through the function of genes for breeding experts. " Zheng Ruifeng said that intelligent breeding in the future, relying on artificial intelligence, big data and biotechnology, will be more efficient and accurate.

  Of course, the powerful function of this pair of glasses depends on the breakthrough of basic research. "The reason why the introduction of low cadmium gene has achieved results for more than two years is because the functional sequence of low cadmium gene is very clear." According to Ye Rongjian, there are about 50,000 genes predicted in rice. At present, about 4,000 genes are cloned and their functions are clear. It may take many years for a gene to know its functions, and the road ahead is still very long.

  "The laboratory not only undertakes the task of detection and analysis, but also explores the mystery of genes." Nie Dongming, the seed administrator, pushed open the heavy security door, and a germplasm resource bank with more than 100,000 rice materials was presented. Here, at the temperature of 4 degrees Celsius, the seeds enter a dormant state and can be safely stored for 5-mdash; Ten years.

  Zhou Hua said that the germplasm resource bank is a treasure house for creating breeding materials. At that time, Academician Yuan Longping discovered the special material of wild rice sterile plant "Wild Abortion" in Sanya, and achieved the breakthrough of hybrid rice breeding.

  R1607′ s breakthrough in rice blast resistance is also due to the germplasm resource bank. "At that time, we were making a breakthrough in the technology against rice blast. I heard that the Chinese Academy of Sciences discovered a gene with strong resistance, but breeding experts did not have this material at hand. We went to the germplasm resource library to search and found the original material. " Zheng Ruifeng introduced that this peasant variety was used to cross and backcross with indica rice varieties, and a series of materials containing rice blast resistance genes were bred.

  "If things in nature are lost, you may not find them when you want to use them in the future. The importance of the germplasm resource bank is now more and more deeply understood. " Zheng Ruifeng said that it is a source protection when its value is not clear and the advantages of germplasm resources are not tapped.

  Zhou Hua introduced that China Seed Group and Yazhouwan Seed Laboratory jointly issued a list for the first-class scientific research institutes and universities in China, and Industry-University-Research jointly integrated gene resources, and there were more than 10 topics in the field of rice alone. In addition to further cooperative research on low cadmium genes, there are also cooperation in herbicide resistance and rice false smut resistance. "The goal is to make excellent rice varieties full of treasures."

  Seed production — — Hainan dongfang

  One mu of seed production can be used for more than 100 mu of fields.

  "Yanmei, throw me the seedling!" "Good, then!" Fu Yanmei didn’t lift her head. A bunch of tender rice seedlings came out and flew over eight or nine women who worked hard, drawing an arc over the paddy field and accurately "delivering" it to Zeng Yabei.

  On February 3rd, gancheng town, Dongfang City, Hainan Province, after the Spring Festival, seed production and rice transplanting have been busy for more than a week. The villagers cooperated skillfully, transplanting rice in the field, and there were bursts of laughter from time to time.

  Such busy and cheerful scenes often appear in the process of seed production. In the whole seed production process, the most attractive thing is heading and flowering, which is also called catching powder.

  At the end of October last year, in this field, the reporter witnessed a scene of catching powder. The sky clears up, the temperature rises, the male parent and female parent materials in the rice field bloom and spit, and pale yellow flowers are dotted with light green ears of rice swaying gently in the breeze. A 40-meter-long rope hangs in an arc on the ear of rice. The two workers each held one end and walked quickly forward in parallel. Where the rope passed, the ears of rice touched, the stamens trembled, the pollen floated to the pistil of the female parent, and suddenly a pale yellow powder fog was stirred in the field.

  Wang Shiming, general manager of Hainan Nongle Nanfan Technology Co., Ltd. said: "Breeding is to bring a bag of seeds and carry a bag of seeds back. Seed production is different. One acre of seed production can be used for more than 100 acres of fields. "

  There are many seed production processes, so it is necessary to plant seeds in reverse order to let parents meet this flowering period. For example, it takes 100 days for the male parent of Quanyou 607 to plant and 80 days for the female parent, so the male parent should plant 20 days in advance; After that, we constantly observe the leaf period, analyze the flowering period, and sometimes adjust it through water and fertilizer to ensure that the flowering period meets.

  "Artificial powder driving can improve the seed setting rate of hybrid rice." Wang Shiming introduced that many years ago, there were as many as 100,000 people in Hainan from Pingxiang City, Jiangxi Province. In recent years, the country has revitalized the seed industry, and Pingxiang has also introduced measures such as subsidies for large seed producers and subsidies for grain production. Encouraged by this, many Jiangxi farmers who have produced seeds in Hainan have returned to their hometowns for development.

  "Raising seedlings, transplanting seedlings, heading and pollination, harvesting and drying seeds, selecting seeds and packaging, I can play when I am young." Wang Shiming has been following his parents to Hainan for more than 20 years. His skin is tanned and he speaks slowly. In 2022, Dongfang City, where he lives, was recognized as a national seed production county, with a million mu of fertile land in Thanksgiving Plain. "Winter seed production starts at the end of December every year, and the seeds are harvested in April and May of the following year, which is just the time for the middle and lower reaches of the Yangtze River."

  Affected by rising land rent and labor costs, Hainan rice seed production has been moving westward, from Sanya to Ledong Li Autonomous County, and then to Dongfang City. "The average annual land circulation per mu in the East is 1,300 yuan, but it has already exceeded 3,500 yuan in Sanya." Wang Shiming said.

  In the middle and late September of 2022, Wen Mincao, deputy manager of the production department of Zhongzhong Agricultural Science and Technology Company, received an urgent task. When the seed production area of Quanyou 607 Hainan suddenly increased from the original six or seven thousand mu to more than 20,000 mu, his head was buzzing. Where can he find the producer and production base?

  The Chinese company implements the order system and gives plans to manufacturers and professional teams all over the country every year. However, the farming season in the mainland has passed in winter and it is difficult to produce seeds; Although Hainan can produce seeds, it is also the winter melon and vegetable season, with less open space, high land rent and early seed delivery time. At one time, it is a bit intense to "grab the base".

  Thanks to Wang Shiming’s contacts in many ways, Wenmin Cao took only one week to reach an intention on 6,000 mu of land and finally breathed a sigh of relief. "Seed production counties support the integration of production, processing, warehousing, packaging and logistics. With favorable policies, we have signed a cooperation framework for the integration of production and supply chain with local manufacturers, which can be produced locally, packaged locally and sent to the market, and can be stored locally if they are not sold out."

  All the efforts are worthwhile.

  In the middle and lower reaches of the Yangtze River, farmers who have tasted the sweetness have long been thinking about good seeds. In Shilou Village, Wudian Town, Zaoyang City, Hubei Province, Chen Bangguo, a large grain grower, called Qiu Yunze, a seed dealer in Wudian Town, after planting winter wheat.

  "Good seeds are in demand! When we tried to plant Quanyou 607, it was Laoqiu who came to sell it, and he guaranteed it, saying that it was not good to compensate my output. As a result, two or three hundred kilograms of rice were added to an acre of land. I am happy to invite Laoqiu to eat! " Chen Bangguo said.

  "In the early stage, we will build a model field display, and invite large households to go to the scene to observe the harvest and yield measurement, so that more farmers can see the comparative advantages of varieties. In the later stage, collect information about high-yield farmers, make posters, and organize seedling meetings from seedling stage to heading stage to expand influence. " Speaking of the promotion experience of good seeds, Wang Hanyong, deputy sales manager of Hubei Branch of China National Seed Group, talked endlessly.

  The field of hope, season after season, the story of a fine variety will be told constantly.

  Planning for this issue: Yin Xinyu, Wu Yan and Cheng Juxin
