Yuan Longping's inspirational story

1in August, 949, Yuan Longping graduated from high school at the age of 19. He decided to leave Nanjing and go back to Chongqing to study at Agricultural College. When he arrived at Southwest Agricultural College, he was even more at home, with only one glory: saving a person. The ballad of his exam scores circulated in the class: "Three points are good, three points are good; Not greedy for the dark, not getting up early; Do not repeat grades, do not make up exams. "

1953 after graduation in August, the whole class was assigned to all parts of the country, and the farthest place was Xinjiang to study cantaloupe. After reporting to the Hunan Provincial Department of Agriculture, Yuan Longping took a charcoal car and bumped all the way to Anjiang Agricultural School, which is 4 kilometers away from Anjiang Town, Qianyang County. This stay is 16 years.

The young teacher from a big city has a class that students like. The student recalled: "He did well in class and played with the students after class. "He didn't pay much attention to it. The blackboard is full. He shrank his hand, grabbed his sleeve and wiped it. "

Try to escape the disaster

1In July, 960, a "natural hybrid rice" was found in the experimental field in Yuan Longping, which stood out from the crowd. However, the seeds of "big rice" were sown in the second year, and the yield was very low. However, this natural hybrid rice inspired him to cultivate high-yield hybrid rice through artificial hybridization. Six rice male sterile plants were found in 1964 and 1965 in Yuan Longping.

After two years of experiments in 60 pots, he successfully cultivated a "male sterile line". In February, 1966, he published his first paper, Rice Male Sterility, in the Journal of China Academy of Sciences, Science Bulletin. After seeing this, a leader of the Ninth Bureau of the State Science and Technology Commission sent a letter asking Hunan Science and Technology Commission and Anjiang Agricultural School to support Yuan Longping's experiment.

Shortly after the "Cultural Revolution" began, Yuan Longping, a typical "white expert", was not spared. Dozens of his "bourgeois pots and pans" were "completely smashed", and the bags of seedlings he picked up were quietly hidden in the gutter behind the school. Just as he was about to be arrested in the bullpen, the working group found this official letter from the school file.

Therefore, Yuan Longping saved the day and became the protected object. What he didn't expect was that the provincial science and technology commission also listed "rice male sterility" as a scientific research topic, allocated him scientific research funds, and two students who came to the commune task force were also agreed to stay as his teaching assistants.

But the seedlings were destroyed again. 1968 One day in May, the experimental field was trampled to powder and the seedlings were pulled out. He picked up five half-buried seedlings from the mud beside the ridge. To Yin Huaqi's surprise, Yuan Longping went on working and didn't investigate who did it. "He is the kind of person who doesn't remember the pain when he falls." .

Later, because two assistants wrote to it, it attracted the attention of the Provincial Science and Technology Commission and the Agriculture Department, and set up a scientific research cooperation group to transfer him to Changsha.

Open scientific research

From June 5438 to 10 this year, Yuan Longping and others began to travel to Yunnan and Hainan, where the climate was hot. By searching for information, he found that Hainan has the most wild rice resources, so in the autumn of 1970, several scientific research teams went to Nanhong Farm in Ya County, Hainan Island. At this time, People's Daily has just published a commentary on Dazhai in Agriculture. Later, Yuan Longping proudly said: "Doing scientific research outside has become a' bard', regardless of both ends."

Feng Keshan, a technician from Nanhong Farm, listened to Yuan Longping's class and realized that the "fake grain" near the farm was probably the wild rice they were looking for. They crawl in groups, with few and small thorns, and they fall off at the touch, looking like weeds. He invited Mr. Yuan's assistant Li Bihu to identify them together, and then dug back a bag of rice ears with abnormal male flowers and thin but undivided anthers. This wild rice named "Bai Ye" later became the female parent of all hybrid rice.

197 1 At the beginning of the year, the State Science and Technology Commission and the Ministry of Agriculture organized the National Cooperation Group. In late March, more than 100 agricultural technicians from 18 scientific research units all came to Nanhong Farm. At this time, the first generation of "wild-defeated" hybrids were heading, and no one knew its scientific research value, but Yuan Longhu distributed the "wild-defeated" materials to everyone for experiments without reservation.

"He is very open-minded in everything and hates that conservative and selfish approach." Luo Xiaohe, a teacher of Hunan Agricultural College, joined this research group on 1970. He found that Yuan Longping had never been on the top of the mountain. As long as he is interested in this subject, he welcomes it. He has not reserved any lectures for other units.

Many people made great efforts. Soon, after tens of thousands of backcrosses between thousands of varieties and "Bai Ye", several excellent sterile lines and maintainer lines were cultivated in Hunan, Jiangxi and Fujian. From 65438 to 0974, Yuan Longping bred the first strong combination "Nanyou No.2" in China. After experimental planting, the yield of rice in both seasons is more than 30% higher than that of conventional rice.

Later, he designed the cultivation mode of intercropping between the male parent and the female parent, and also invented the indigenous method of "driving away pollen" with bamboo poles, which increased the seed yield from 5.5 kg per mu to more than 40 kg.

1976 is a very special year. In the paddy field, the sparse hybrid rice has grown thick and full particles. The area of hybrid rice began to expand rapidly. By 1998, half of the paddy fields in China had been planted with hybrid rice. 198 1 June, 2008, Yuan Longping, who had a naked crew cut, went to Beijing and won the first and only special invention award in China.

A casual old man

Now, his office is full of medals and certificates. But the old man still insists on doing scientific research in the front line. Every winter, he goes to Sanya base. Once he climbed the ridge, and the people next to him tried to give him a hand, but he stopped him. "You think I'm old, I'm faster than you young people!" Yuan Longping, who became famous and married, still seems to like a free life.

He goes shopping on business occasionally. When he sees cheap clothes, he will put them on himself first, then on his assistant and buy a lot of clothes. When he comes back, everyone will send one. A hybrid rice fund has also been set up to reward young and middle-aged scientific and technological workers with achievements.

He often tells people his dream twice: the rice in the field grows as tall as sorghum, the ears of rice are as long as brooms, and the grains are as big as corn. When he and his assistants are tired, they will chat under the rice to enjoy the cool. At first, everyone around him laughed. After a long time, he found that all he could think about was this matter. He sent all his young assistants with good English abroad for further study, for his second ideal: spreading hybrid rice and "benefiting the whole world".

His assistant Liao Fuming said with emotion: "Mr. Yuan is a happy man with pursuit and freedom."

The old man brought good news again!

It is understood that the expert group for yield measurement consists of seven experts from Huazhong Agricultural University, China Agricultural Science and Technology Innovation Alliance, hebei academy of agriculture and forestry, Hebei Soil and Fertilizer Station, Hebei Engineering University and Handan Agriculture and Animal Husbandry Bureau Soil and Fertilizer Station. The expert group measured the yield of the 100-mu high-yield research film "Xiangliangyou 900" with the planting area of 102 mu in the base.

On the basis of field investigation, the expert group randomly selected three plots for manual harvesting, mechanical threshing and actual harvesting, with a total harvesting area of 3. 126 mu, and the yield per mu of the three plots were 1 18 1.00 kg and1/kloc-0 respectively.

What does it mean to make a breakthrough in cadmium removal technology for rice parents?

What does Yuan Longping mean by "knocking out" cadmium-containing genes in rice? Perhaps this concept may not be easy for many non-professionals to understand, but it is closely related to each of us!

According to Hunan Daily, in recent years, with the new requirements for green seed industry put forward by the structural reform of agricultural supply side, the purity of crops has been paid more and more attention, especially in many areas with serious soil pollution. How to avoid the intergenerational transmission of pollution elements in crops is a problem that breeders must consider.
