Striving spring ｜ Cultivate a good plant and a fertile field.

　　Changchun, China, March 11 (Reporter Guo Dongyu) How important is a good seed for food production?

　　"Good seeds, good rain and good moisture can make us look forward to a bumper harvest year." Han Fengxiang of Fenghuangshan Agricultural Machinery Farmers’ Professional Cooperative in Lishu County, Siping City, Jilin Province said.

　　"The contribution rate of excellent varieties to grain production has reached more than 45%, which plays a vital role in national food security." Zhang Zhijun, a researcher at the Corn Research Institute of Jilin Academy of Agricultural Sciences, said.

　　"I have a dream, buried in the soil, convinced that it is different. Light gives it hope, rain nourishes it and grows with the seeds. " Yuan Longping, the father of hybrid rice, said.

　　This year, the No.1 Document of the Central Committee proposed that the seed industry should be revitalized in depth, the pace of industrialization of corn and soybean biological breeding should be accelerated, the pilot scope should be expanded in an orderly manner, and planting management should be standardized.

　　Recently, the reporter walked into Gongzhuling City, the founding unit of the National Modern Seed Industry Park and a national-level rice seed production county, to see how Jilin people on the black land grasped the "core" of grain.

　　In the more than 20,000 mu seed field of Hongxiang Seed Industry Co., Ltd. (hereinafter referred to as "Hongxiang Seed Industry") in Gongzhuling City, the land has been turned over and the organic fertilizer has been piled up at the edge of the field. "This seed production base was transferred last year. We used the method of black land protection to produce seeds. After a year of practice, the seed quality is very good." He Wei, general manager of Hongxiang Seed Industry, said.

　　Walking into the seed cultivation room, a fresh new green brings ying ying spring. "This is our trial variety and we are testing the emergence rate." He Wei said, "The seedlings in this germination box grew the day before yesterday, and each leaf of them contains a lot of information, which is very important for us breeders." Here, enterprises invest about 50 million yuan in maize breeding every year. "We carefully selected the seeds and planted them in the experimental field. Through the growth and yield, we found those plants with less diseases, lodging resistance and high yield."

　　In addition to constantly researching and developing new varieties, how to make seeds more suitable for modern agricultural production methods is a problem that the Corn Research Institute of Jilin Academy of Agricultural Sciences is currently thinking about.

　　"At present, one of the main problems in corn production is that the level of mechanized harvesting of seeds is low. At present, the harvesting method is mechanical harvesting of ears or manual harvesting, which is not conducive to large-scale production." Zhang Zhijun, a researcher at the Corn Research Institute of Jilin Academy of Agricultural Sciences, said.

　　In recent years, the corn research institute of Jilin Academy of Agricultural Sciences has taken the research and development of new varieties suitable for modern production methods as its main research goal. "At present, we have cultivated Jidan 66, Jidan 436, and Jidan 81 and 82, which will be approved soon. It can be said that grain harvesting is a strong support for Jilin agriculture to take the lead in realizing agricultural modernization in the future." Lu Ming, deputy director of the Corn Research Institute of Jilin Academy of Agricultural Sciences, said.

　　Document No.1 of Jilin Provincial Party Committee issued this year made it clear that it is necessary to implement the project of improving corn yield per unit area. Screening and popularizing new maize varieties with density tolerance, high resistance and high yield.

　　"Every seed we develop must first ensure safety and good resistance. No matter what kind of environment, it can grow. The second is high yield, which allows farmers to increase their output after planting. " He Wei said. Hongxiang Seed Industry plans to reach the production capacity of all four design production lines as planned before 2025, meeting the production demand of 100,000 mu. "In the future, we can serve the whole park, let the seed industry in Jilin Province come back and build a spring corn processing base."

　　It is the wish of Jilin breeders to cultivate a good seed and plant a good field, and it is also the road they will always stick to.
