Ensuring the safety of seed sources and national food security


The report of the 20th National Congress of the Communist Party of China proposed that "the seed industry revitalization action should be implemented in depth". Seed is the foundation of agricultural modernization. In recent years, various regions and departments have continued to strengthen their strengths and weaknesses, complement their weaknesses, aim at the links such as variety selection and promotion, accelerate the revitalization of the seed industry, and firmly hold the seeds in their own hands. With the increase of varieties, farmers have more choices in Tuyuan Town, Sucheng District, Suqian City, Jiangsu Province. The fields are covered with green wheat seedlings. "The wheat we selected this year is a new variety. It is estimated that the number of ears per mu will increase by 100000 ears and the yield per mu will increase by more than 100 kg." Zhuang Yunfei, a grain farmer in Tuyuan Town, said. Zhuang Yunfei started to cooperate with Jiangsu Ruihua Agricultural Technology Co., Ltd. in 2015 to breed new wheat varieties in the form of order entrustment. "The seeds of Ruihua Company are very secure in disease resistance and high yield." Laozhuang said, "With good use of seeds, the benefits of farming are getting better and better." Not far from Laozhuang's wheat fields, it is the comprehensive demonstration base of modern agriculture (rice and wheat) science and technology in Jiangsu (Suzhou). The experimental fields were arranged orderly, with "ID cards" indicating varieties stuck in the fields. "The demonstration base is conducting screening tests for new wheat varieties with high quality, high yield and disease resistance. The company invests more than 10 million yuan in R&D every year, accounting for about 8% of the sales revenue." Xia Zhonghua, general manager of Jiangsu Ruihua Agricultural Science and Technology Co., Ltd., introduced that the newly selected "Ruihua Mai 549" is expected to have a yield of 750 kg per mu. The company cooperates with more than 30 local large grain growers to increase their income by more than 100 yuan per mu. In recent years, Sucheng District has vigorously promoted the construction of the "Sucheng of seed sources", invested about 50 million yuan in breeding innovation research and development every year, built a germplasm resource bank of 2000 cubic meters, collected more than 30000 germplasm resources, and achieved self-sufficiency of major crop varieties. "Golden Seed" enables farmers to produce more food with less money, and the rich new varieties also give more choices to farmers. In the middle of winter, the wheat field outside Laoyazhang Village, Juqiao Town, Qibin District, Hebi City, Henan Province is full of green. Wang Guoxiang, a grain farmer, is squatting in the wheat field, fiddling with the wheat seedlings to check the wheat growth. More than 200 mu of land contracted by Wang Guoxiang is planted with wheat "Bainong 4199" this year. Wang Guoxiang is familiar with the characteristics of this variety: "It has high photosynthetic efficiency, high light saturation point and low compensation point. It can not only resist strong light and weak light, but also resist disease, lodging and high temperature." He introduced to the reporter in detail, "Although the yield of this variety is not the highest, after several years of trial, it has the characteristics of stable yield and early maturity, which is most suitable for large-scale planting." Wang Guoxiang, who has spent more than 20 years in the farmland, has a deep understanding of the importance of seeds: "Although more than 300 mu of land I transferred is in continuous blocks, the cultivated land itself is quite different. Some plots are a little dry, some are not fertile enough, and some are far from the water source. Previously, all plots could only grow the same variety, and the yield could not be guaranteed." Now, with the development of seed industry, more than ten new varieties will appear in the market every year. Wang Guoxiang can choose different varieties to plant according to the actual situation of the land,
