Science and Technology Star of Hunan | Liu Zhongsong: Exploring the "treasure" of rapeseed, only for vegetable oil to fragrant

【business card】

Liu Zhongsong, a second -level professor at Hunan Agricultural University, a doctoral supervisor, a scientist of the national rapeseed industry technology system, director of the Hunan Branch Center of the National Oil Reform Center, Director of the Key Laboratory of Rape Biology and Genetic Breeding in Agricultural and Rural Ministry, enjoy the State Council and Hunan Provincial Government Special allowance experts, the main research direction is rapeseed breeding. The breeds raised by the team have promoted more than 150 million acres to the appropriate planting area across the country, increased more than 30 billion kg of rapeseed, and increased their income of about 15 billion yuan. In 2022, he was awarded the "Most Beautiful Science and Technology Worker" in Hunan Province.

On the evening of September 20th, the 437th office of Longping Building at Hunan Agricultural University was still brightly lit. Just after Changde returned rapeseed planting classes for local farmers and agricultural technicians, Liu Zhongsong had too late to go home, and was busy studying a group of mustard rapeseed resources brought back from Guizhou to see if there were new discoveries.

How to turn beautiful rapeseed into delicious vegetable oils and protect my country's grain and oil safety, Liu Zhongsong has gone through the road of 36 years.

Oath the excellent germplasm resource "holding in your hand"

Hunan rapeseed planting area ranks first in the country, and the types of rapeseed widely planted are cabbage -type rapeseed. However, this traditional variety of rapeseeds generally exists in the shortcomings of "not resistance to disease and difficult to resist". Moreover, it is naturally black seeds. The "squeezed" vegetable oil was not favored by the market because of "black", but if it was discolored, many nutritional ingredients would be taken away.

The mustard rapeseed is naturally "beautiful", which is not only yellow seeds, but also resistance to drought and drought. Since the 1980s, Liu Zhongsong began the road of research, hoping to unlock more large amounts of genes behind mustard rapeseed, so that it can cultivate new varieties as pro -mixed hybrids.

"Put more excellent germplasm resources in your hands to make breeding more possibilities." Liu Zhongsong admits that the variety of mustard rapeseed resources are mostly distributed in arid and barren land. The more forward ".

During the survey and collection of Yili in Xinjiang, he and the team had experienced a magnitude 6.6 earthquake; during the collection of materials in Xinfa Township, Weining County, Guizhou, due to the steep slopes of the mountains, the vehicles had rolled over ... After accumulation, he and his team finally got more than a thousand species of quality resources.

With resources, breeding has a "source of living water". Through the first consequences of the first rapeseed mustard gifted breeding, he and the team finally realized the excellent traits of the mustard rapeseed towards cabbage -type rapeseed! The newly cultivated new cabbage -type rapeseed varieties with precocious high -yield and high -yield of yellow seeds, which have been cultivated.

"We recently selected yellow seeds and rapeseed varieties' alcohol Xiang oil 272 '' oil content is as high as 49.36 %; the new variety 'Xiang Miscellaneous Oil 512' '' Xiang Miscellaneous Oil 356 '' 'Xiang Miscellaneous Oil 518' 'Xiang Miscellaneous Oil 631' is already in Hunan and surrounding provinces have promoted more than 60 million acres ... "Speaking of recent results, his joy was overwhelming.

Innovative and excellent variety "still on the road"

Draw a regular form, use a pencil to record the source, name, oil score, and high oil acid ... Each year, Liu Zhongsong will focus on the field in the "summer" and "autumn broadcast" season, and record the results of the results of the inspection one by one On the small book. The wind and rain are 36 years. Now, the little book "has become a pile."

Liu Zhongsong, who is nearly 60 years old, "is always the latest after get off work, and Xia Tian is more active than anyone else." The team members "often feel uncomfortable, and they are full of respect."

"This may be related to my experience." Liu Zhongsong told reporters that when he was working in the Agricultural Sciences in the 1980s, he had three years of experience in poverty alleviation in Yongshun County, western Hunan. The closeness to "stepping on the soil and penetrating into the farmer" fascinated him. He felt that this was the "charm" of agricultural scientific research and "necessary". Since then, "pragmatism" has become his research belief.

"All scientific research is to let the people live a better life." Liu Zhongsong said that molecular breeding technology is becoming increasingly mature. How to make rape breeding help the village's revitalization is the field of his main attack in recent years.

In 2020, as a provincial special agent, he went to Pinghe Village, Yizhang County, Luzhou, and jointly built the southernmost rapeseed research and production base with villagers. He vigorously carried out the promotion of high -quality rapeseed varieties and cultivation technology, and drove 3,000 acres of rice farming fields in the village to plant rapeseed rapeseed, which can increase the income of about 200 yuan per mu. Increasing the income of nearly 1,000 yuan ... He worked hard step by step, so that the local area gradually showed the beautiful scene of "rich farmers and beautiful scenery".

He has been deeply cultivating soil and fighting for the first line of scientific research. "Walking fast" has become Liu Zhongsong's habit, and now he is still running. How to further "improve intelligent design molecular breeding" and "promotion of rapeseed mechanized production", so that rapeseed planting has achieved higher efficiency, and the higher -quality vegetable oil is fragrant, which has become his new "poem and far away".
