New Jiangsu China Jiangsu Network News (reporter Guo Yani) "Selective breeding, a lot of materials are personally pulled down by the end, decades down, his right index finger deformed and bent, thumb fingerprints are also worn off and can not be seen clearly." ”
This is the detail that the young researchers were most impressed by the "Duan Institute", the former director of the General Agronomy Office of the Changshu Agricultural Science and Technology Research Institute, and the rice breeding expert Duanmu Yinxi. In their eyes, Duanmu Yinxi is a banner.
For more than 50 years, Duanmu Yinxi has worked hard in the field of rice breeding, devoted himself to cultivation, and has bred 37 new rice varieties such as "Taihu Japonica Series", "Changyou Series", "Changnong Japonica Series" and "Changxiang Japonica Series". Academician Yuan Longping, china's "father of hybrid rice", called him "a rare real rice breeder".
The simplest dream: to breed good seeds, so that farmers can eat well
In 1947, Duanmu Yinxi was born in the countryside of Changshu. "Bitter origin" is his evaluation of his early experience. When he was a teenager, it coincided with three years of natural disasters, and Duanmu Yinxi, who was growing his body at the time, was extremely hungry. At the age of 16, his father passed away, and he had just graduated from junior high school and had to give up his dream of studying, go to the production team to participate in labor, and earn some work to fill his stomach. At the age of 18, Duanmu Yinxi was recommended to the commune agricultural technology station and became an agricultural technician. Since then, his life has been closely linked to agricultural science and technology.
Only good rice seeds can grow high-yielding rice, and only high-yielding rice can feed everyone. He has always been in the field, and he deeply understands the importance of good seeds to farmers. Duanmu Yinxi planted a dream to cultivate good rice seeds so that farmers would no longer starve and eat well.
In 1976, Changshu established the County Institute of Agricultural Sciences and began to tackle the cultivation of fine seeds. After the examination, Duanmu Yinxi was transferred to the institute to specialize in rice breeding.
The more you go on the professional road, the more in-depth knowledge is required. Duanmu Yinxi realized his lack of professional knowledge and began to teach himself. Every day before going to work, he studied for two hours, and then studied for a few hours after work in the evening, six years, with amazing perseverance, he got a college diploma.
For breeders, practical experience is even more valuable. His peers became Duanmu Yinxi's teacher, and when he heard that the agricultural science institutes in the surrounding brother counties and cities were very active, he went to the door to ask for scriptures. In the 1990s, after getting acquainted with Academician Yuan Longping, the "father of hybrid rice", he often took the initiative to consult. Every April, Yuan Longping's team will hold a hybrid breeding exchange report meeting, and Duanmu Yinxi will arrive every time.
Chase the sun, two summers a year
In mythology, it is the father who chases the sun, and in reality, it is the breeder who chases the sun. Changshu is located in the subtropics, winter and spring is not suitable for rice breeding, in order to speed up the process of breeding, every year in mid-to-late November in Changshu after the completion of rice determination, Duanmu Yinxi chased the sun to Hainan, taking advantage of the warm winter climate in the south to breed again, until the end of April of the following year.
2021 is the 26th year of Duanmu Yinxi's arrival at the Hainan base. At the beginning of the year, Duanmu Yinxi underwent cataract surgery. "If you are not in good health, rest at home", the persuasion of his family did not shake him, and before he could rest well, Duanmu Yinxi wore thick sunglasses and once again embarked on the journey to the south. Sanya is perennially hot and has strong ultraviolet rays. The changshu institute of agricultural sciences is located in a ravine on the outskirts of Sanya, where mosquitoes are infested with mosquitoes and poisonous snakes. At work, Duanmu Yinxi and the research team members must wear heavy and stuffy long sleeves and go to the field. Under the scorching sun, the clothes are covered with alkali spots of white flowers.
Rice flowers often only take a few tens of minutes, in order to capture this best time, the breeding team is standing by the whole time, staring at the rice spike, watching it grow and blossom little by little. "Because of the long years of working in the sun, sweat flowed into the eyes and could not be wiped, and for many years, Dad's eyes were greatly damaged." Daughter Duanmu Hongying said. Cervicitis, eye nerve disorders, facial spasms... Overloaded in harsh environments for many years, Duanmu Yinxi suffered from a variety of diseases, and on several occasions even fainted in the fields and dormitories, frightening his assistants.
"If you eat bitterly, you will be a breeder." These are the words that Duanmu Yinxi often hangs on his lips. From field layout to pull-line transplanting, from shearing bagging to artificial pollination, from harvesting and drying to sorting and packing, he does it all himself. Kung Fu pays off, and Duanmu Yinxi's team has harvested in Sanya every year.
Ina-saka Ino, dream of new hair
Any grain species has regional adaptability, and no grain can be planted in the world. Yuan Longping, the "father of hybrid rice", has always been indica rice, and he has always hoped that someone can make a breakthrough in the cultivation of japonica rice.
A straw hat, a pair of long rain boots, a cloth coat, two summers a year, under the unremitting efforts of Duanmu Yinxi and colleagues, in 2000, the new hybrid japonica rice variety "Changyou No. 1" was tested in more than ten experimental points in Jiangsu, Zhejiang, Shanghai, Anhui and Hubei provinces and cities. By 2003, "Changyou No. 1" has passed the national examination and promotion throughout the country, achieving a major breakthrough in China's hybrid late japonica technology.
In October 2011, the Changshu Branch of the National Hybrid Rice Engineering and Technology Research Center was established, led by Duanmu Yinxi, which was the first specialized institution in the field of hybrid rice in the country to study hybrid japonica rice. For breeders, better varieties are always next. Duanmu Yinxi, who has long passed the retirement age, has been sticking to his post.
With the improvement of people's living standards, people's requirements for rice quality are getting higher and higher, and Duanmu Yinxi began to put forward new breeding ideas to select and breed delicious new varieties of rice.
Following the "Changyou No. 1", Duanmu Yinxi led his scientific research team to breed 14 hybrid japonica rice in the "Changyou" series, which raised the quality of rice to a new level while stabilizing high yields. "From the first new hybrid rice variety, Changyou No. 1, to today's fruitful results, each variety is soaked with his sweat and hard work." Dai Junjiang, director of the office of the Changshu Municipal Institute of Agricultural Sciences, said.
Ina-saka Ino, dream of new hair. For more than 50 years, Duanmu Yinxi has been working tirelessly on the scorching sun, stepping on the loess soil, tirelessly cultivating hybrid late japonica rice seeds, and exploring forward with perseverance and perseverance unimaginable to ordinary people. Today, Duanmu Yinxi, who is over seventy years old, is still climbing towards a higher goal, and he is moving towards the goal of producing 1,000 kilograms of high-quality hybrid japonica rice per mu.
