In mid -August, Donglin Village, Laudu District, Chengdu, was growing wildly. The breeze blew, the green rice fields rippled ripples, and the rice fragrance was drifting.
Unlike other farmland, most of the laborers on this land are scientific researchers -this is the test field of the Chengdu Branch of the National Hybrid Rice Engineering Technology Research Center (hereinafter referred to as the "Chengdu Branch"). Harvest has a thicker significance.
This year is the 49th year of the advent of hybrid rice. In 1973, the science and technology research team led by Yuan Longping completed the three -series supporting and successfully cultivated hybrid rice, achieving a historic breakthrough of hybrid rice. In order to promote the research and development and promotion of hybrid rice in the southwestern region, Academician Yuan Longping in September 2005 established the "Chengdu Branch Center" in Yudu District, Chengdu.
Since then, in the southwest land of the motherland, a group of people began to go to the road of increasing grain production, led by the "father of hybrid rice", just to keep the "big country granary".
The Chengdu Branch of the National Hybrid Rice Engineering Technology Research Center landed in Chengdu Laudu District. In 2019, it moved from Yipu to Deyuan and rooted in Donglin Village.
The vitality of a wild rice
Let him decide to take root in agriculture
Short sleeves with middle pants, straw hat on the head, and a pair of slippers. This is Zhang Xiangyang's work. Due to the long -term wind, his face was dark. As the person in charge of the scientific research of Chengdu Branch and Deputy General Manager of Sichuan Taolong Agricultural Technology Co., Ltd., Zhang Xiangyang's first impression is simple enough. "Our job is to go to the ground at any time. This is for convenience."
The endless hybrid rice test field is Zhang Xiangyang's office. On the occasion of the interview, Zhang Xiangyang took off his shoes from time to time, walked into a high -waist rice field, and checked the growth of rice. During this time, Zhang Xiangyang and his colleagues spent a long time to go to the fields to see if the plants grow well, and the Suizi is not big.
"Promote learning and farmers, and the world. To do agriculture, you need long -term investment and more feelings." In the year of sophomore, Zhang Xiangyang was internship at the rice in Sichuan Agricultural University. . "This made him have a strong desire to explore life," too shocking. "
Zhang Xiangyang is from Henan. In his hometown, there is almost no rice planting. After witnessing the wonderful life of life, Zhang Xiangyang decided to take root in agriculture. After graduating from Sichuan Agricultural Seed Science and Engineering, he also studied with Professor Wu Xianjun, a well -known rice expert in Sichuan Province to continue his studies.
When I first entered the industry, Zhang Xiangyang had done a agricultural market. During the survey again and again, he realized the responsibility on his shoulders -the crops often faced various tests during the growth process. The outbreak of rice plague was enough to make the farmers' hard work east. Risks, we can only start with scientific research to improve the ability to resist the variety of crops and reduce farmers' losses. "Seeds are agricultural chips." Zhang Xiangyang said.
After graduating from graduate students, Zhang Xiangyang's employment China Seed Group Co., Ltd. carried out hybrid rice selection. In 2017, he came to the Chengdu Branch to continue to engage in the selection of new varieties of hybrid rice, new technology supporting and promotion of new models.

For one thousandth of hope
Pay 100 % effort
"Tian Tai You 808", "Yayou 5808", "Ruifeng 788", "Tiantai You 33" ... In the test field of Chengdu Branch, a display sign is inserted in front of a ridge of rice The name and sowing date of rice.
"There are almost 4,000 different rice materials here." Zhang Xiangyang stopped before a test field. The crops in front of them have the "appearance" of new rice varieties, but they cannot be called new rice varieties. They are still in the long development process.
Sichuan is located in the southwest of our country and has a special ecological environment of low temperature and widow. This puts forward higher requirements for rice varieties. In fact, agricultural production is very regional. Due to the differences in soil and climate, there are significant differences in varieties of varieties in different areas such as the upstream rice area and the middle and lower reaches of the Yangtze River, and the middle and lower reaches of the Yangtze River.
This is the significance of the Chengdu Branch Center, and it is also the work direction of Zhang Xiangyang and his R & D team: need to use different rice materials to cultivate and screen out the rice varieties that are suitable for ecological conditions in the Southwest. For example, anti -high temperature, disease -resistant pests ...
At the same time, the Chengdu Branch is the leading unit of the "Special Rice Variety Creation and Application Research" project as the "Leading Rice Breeding Materials and Method Innovation and New varieties" project as the 14th Fourteen Fourteen Five -Five Fourteen Fourteen Fourteen Five -Year Sichuan Province. The direction has also increased the direction of new research, such as special rice such as rice wine, rice and fishing, rice and fishing, and field landscape rice.
From the growth of rice materials to an excellent variety that can be promoted in large areas, it is necessary to go through the process of at least 5 to 8 years. "In the end, the variety of‘ licensing ’that can be obtained by the competent agricultural department must be a combination of more advantages than the control variety.”
However, the pass rate is only one tenth. Generally, after a long trial process of 4,000 rice combinations, there are only three or four varieties that can pass the approval and large -scale promotion.
It is precisely because of the extremely low pass rate that the scientific research team will work hard to expand the base every year when screening and testing the rice combination. In 2021, the Chengdu Branch Center screened and tested and mixed rice materials reached 4018, a record high. "Even if there is only one thousandth of possibilities, we have to pay 100 % efforts." Zhang Xiangyang said. Fortunately, hope is always there. Once I went to Chongzhou, Chengdu to investigate, Zhang Xiangyang saw that he had developed and developed the hybrid rice that was successfully developed by hand. A sense of accomplishment that is unspeakable, "worth it."

Inheritance Yuan Longping's concept of romance of rice
Launch the rice and fishing three -dimensional ecological circulation breeding mode
For every agricultural person, Yuan Longping is an inevitable name.
Because of the opportunity of work, Zhang Xiangyang has seen Yuan Longping several times. On a kind of industry forum, he saw that the old man was still running around for hybrid rice careers. "It's like a spiritual monument to guide us to move forward."
Such guidelines also run through work.
In 2005, Yuan Longping proposed the concept of "curve to get rich", that is, simply relying on planting rice can not help farmers to increase their income and become rich. Only by greatly improving the output of the area of rice units can we be adjusted. More land is used for planting and breeding of economic crops to help farmers realize "breeding rice to get rich."
"This is also what we are doing." Zhang Xiangyang pointed at the rice field with a brand of "Tiantai 808". A few years ago, the Chengdu Branch began to choose the breed of rice and fishing. In 2021, the new variety of hybrid rice varieties that were suitable for the comprehensive rice and fishing breeding "Tiantai You 808" was approved. Relying on this variety, you can realize the three -dimensional ecological circulation breeding mode of rice and fishing.
Not far from the "Tiantai Youyou 808" rice fields, a high -level breeding pond is noticeable, "Fields can grow rice, fish can be raised in the pond, and ecological circulation is cultivated." The recycling breeding mode integrated facilities and the comprehensive breeding advantages of fishery and rice and fishing. The comprehensive output value of rice and fishing in one acre of rice fields can be tens of thousands of yuan, which is more than 10 times that of simple breed rice.
It is reported that the Chengdu Branch has also developed the "rice+" rice breed rich models such as the full -process mechanical scale of the super rice, the green high -end efficient and high -quality model, and the water -drought wheels.
Academician Yuan Longping came to Chengdu Branch to inspect
Make a cool dream for Hexia
A generation of agricultural people in generation
Right now, it is the critical period of hybrid rice grouting. This year's harvest is good or not, it can be judged from this month's growth.
Half a month ago, Zhang Xiangyang's six marketing colleagues began to run for the market. What they needed to do was to run 21 prefectures and prefectures in Sichuan to track market tracking. "This year's high -temperature weather is also a test for crops. Fortunately, the news that the feedback is that our variety performs well in various aspects such as high temperature resistance and high yield.
In Chengdu Branch Center, there is another way to develop hybrid rice and inherit the spirit of academicians.
When Yuan Longping was alive, as the deputy director of the branch center, Liu Jinsao went to Changsha to report to Yuan Longping every year. "We are also thinking about how to pass on the spirit of innovation and hard work of agricultural scientists represented by Academician Yuan Longping." Liu Jinsao said.
After several years of preparation, Yuan Longping Hybrid Rice Science Park was completed and opened. This is also the only science park named after Academician Yuan Longping's authorization. The park takes hybrid rice scientific research as its core, and has developed courses for farmers' professional managers and adolescents. The nation's first batch of "scientists spiritual education bases" list.
On May 22, 2021, Academician Yuan Longping died at the age of 91. In order to mourn Yuan Longping, Chengdu Branch has set up a small hanging hall at Yuan Longping Hybrid Rice Science Park. "In two and a half days, almost 50,000 people came here." At that time, Liu Jintao was helping to deal with Yuan Longping's funeral in Changsha, but she followed her. The video sent by the staff saw that the scene was orderly, and the citizens looked solemn and sad. "It must be respect and sorrow from the heart." Liu Jinsao said.
"I had a dream, and dreamed that my rice grew taller than sorghum. The spikes were longer than the broom. The grains were as big as peanut rice. I and my assistant sat down under that rice ears." Yuan Longping used to be in the past. In an interview, he talked about his dream.
Today, sir, but there are generations of rice people inherited his legacy and realized all the food.
