? Before Mr. Yuan's death, the highest yield per mu of hybrid rice in a single season was 1 152.3 kg, and it was hoped that it would exceed 1200 kg before his death. ? Li Jianwu, director of the Department of Cultivation Physiology and Ecology of Hunan Hybrid Rice Research Center, said that this year he and his colleagues set up five experimental sites across the country to tackle key problems, and some of them have achieved this goal.
Are you online? Father of hybrid rice? Hunan Hybrid Rice Research Center, where Yuan Longping worked before his death, has grown up. Yuan Longping's young people who once cared about and had high hopes like rice are following in Yuan Longping's footsteps? Dream of enjoying the cool under the grain? .
From 20 1 1 year? Take classes to study? When the yield per mu of super hybrid rice is 900 kg in a single season, 20 1000 kg will be taken as the backbone in 2004, and then the yield per mu of the third generation hybrid rice will exceed 1500 kg in 2020 and 202 1 for two consecutive years. Take the lead? In the process of growing up, 37-year-old Li Jianwu deeply felt Yuan Longping's care and trust for young people.
In the winter of 2008, Li Jianwu, who had not graduated at that time, went to Sanya for an internship and participated in scientific research experiments. One day, Yuan Longping, who visited the experimental field, was found in a place? Especially good? Attracted by the magnetic field, he asked? What kind is it? ? Li Jianwu was pulled by instructor Deng to Yuan Longping's side and looked at Li Jianwu who was tanned. Yuan Longping even asked several questions, and Li Jianwu answered them one by one.
Going abroad is success? Shortcut? . Li Jianwu has always remembered Yuan Longping's teachings. Every time he tries to solve a key problem, he needs the cooperation of farmers in the experimental field. In order to convince and guide everyone, Li Jianwu will eat and live with his fellow villagers for several months in a row to ensure the smooth implementation of the carefully designed planting plan.
From Yuan Longping 20 18? Three points to support a person? High-yield, green and high-quality grain science and technology innovation project (hereinafter referred to as? Trinity project? ), Li Jianwu has always been the main person in charge of the project. 202 1 year,? Trinity project? Increase grain output by 209,000 tons and increase economic benefits by 430 million yuan. In June of the same year, 5438+ 10, he and his colleagues increased the yield per mu of the third generation hybrid rice from 1530.76 kg in 2020 to 1603.9 kg.
China has 10 billion mu of saline-alkali land. Yuan Longping once said, I hope to be among them? Rebuild 100 million mu of fertile land? And put it forward on 20 19? Make breakthroughs in breeding in the near future, improve technology integration in the medium term, and achieve double improvement of productivity and efficiency in the long term? Three goals.
On March 16 this year, an important step was taken to realize this dream: the National Salt-tolerant Rice Technology Innovation Center, composed of 1 1 units in seven provinces in China, was officially listed. Hunan Hybrid Rice Research Center, the lead unit, set up a special group. After 80 s and 90 s? Young people account for 70% of the total number of the team.
Guo, deputy director of the management department of the experimental base of Hunan Hybrid Rice Research Center, was born in 1986. He mainly worked in four regional centers in Northeast China, Northwest China, South China and East China, and worked with experts to continuously tackle problems related to salt-tolerant rice.
Guo said that young people are very motivated, and often after 10 in the evening, the office building of Hunan Hybrid Rice Research Center is still brightly lit.
Their efforts have brought exciting results: at present, nearly 65,438+10,000 mu of saline-alkali land has been improved and 600,000 mu of saline-alkali tolerant rice has been planted. Experimental fields such as Xing 'an League in Inner Mongolia, Kashgar in Xinjiang, Yazhou in Hainan and Nantong in Jiangsu have set new records for rice yield per mu in different types of saline-alkali land. In addition, they have made breakthroughs in soil directional regulators and plant growth regulators.
? I have worked and studied with Mr. Yuan for nearly 10 years, and he has always warned us young people? Farming is no small matter? . ? Say, Guo? The cultivation of salt-tolerant rice especially embodies the weight of this sentence. Turning wasteland into fertile land is an important measure for us to safeguard national food security. ?
Mi Weiwei, 30, always remembers Yuan Longping's emphasis on the details of international promotion of hybrid rice. ? In the past, as long as the center held international training courses, Mr. Yuan would personally issue certificates of completion to students from all over the world. ? Mi Weiwei 20 15 entered the Ministry of Industry of Hunan Hybrid Rice Research Center. In her impression, Yuan Longping always knows the nationality of each student in advance, and then tells the students a few words according to the specific situation of local hybrid rice.
Although the training course was changed from offline to online due to the COVID-19 epidemic, Mi Weiwei and his colleagues did not interrupt the international promotion of hybrid rice.
Over the past two years, she has been busy assisting China experts and overseas staff to update courseware to ensure that the training content conforms to the local reality. Last year, they passed? Cloud teaching? Through other ways, more than 0/00 agricultural technicians in Madagascar/KLOC will be taught intensively, so that they can better serve local farmers.
More than a year ago, in Nigeria, Hunan Hybrid Rice Research Center started the development of hybrid rice industrial chain, and cooperated with local authorities in technical training to conduct hybrid rice seed production experiments. In Guinea, the center has also begun to contact local enterprises willing to invest in the development of hybrid rice industry (Xinhua News Agency reporter Zhou Mian)
