Keshan County is located in the western part of Heilongjiang Province and northeast of Qiqihar. Keshan has a land area of ​​about 3,320 square kilometers and a cultivated area of ​​about 3.02 million mu. Keshan Materialized Tianbao, with fertile soil and unique agricultural advantages, is the national key commodity grain base county, soybean export base county and potato base county. It is known as the “Northern Granary” and “Soybean Town”. Keshan County is located in the hinterland of the Songnen Plain in the world's three major black soil belts. It is located in the world soybean soybean production area at 47 degrees north latitude and enjoys the reputation of “China's high-protein soybean town”. The Ministry of Agriculture listed Keshan County as a non-GM soybean production protection zone in China. A large part of the reason is due to its superior natural conditions, excellent ecological environment, high mechanization level and strict standard of green organic food production.

Fertile and safe soil, rare underground mineral springs, moderate fertilizer, gas and heat conditions have made Keshan natural high-quality “granary warehouse”, and Keshan is a crop cultivation area, which produces high and balanced nutrient content. The data show that the soybean grains in Keshan County are full and firm, and the crude fat content of the main varieties is 22.1%~25.4%, and the crude protein content is 42.1%~46%, which exceeds the national standard. According to reports, all the soybeans grown in Keshan are non-transgenic high-protein and high-oil special varieties, and the area is kept above 1 million mu per year. It is called “hardcore” crops by Keshan farmers. The large-scale land and advanced large-scale agricultural machinery have made the agricultural production process of Keshan precise, ensuring the uniformity of Keshan soybean quality. In addition, the Keshan Branch of the Heilongjiang Academy of Agricultural Sciences and other units have successively cultivated a number of excellent soybean varieties suitable for planting in Keshan and surrounding areas. The production is strictly in accordance with the green and organic production rules, soil testing and formula fertilization, mechanical farming, integrated pest control, and the standardized planting rate is as high as 98%. Excellent quality has earned a good reputation for Keshan soybean. At present, there are 11 soybean green food labels in Keshan County. Keshan has also become the main raw material base of many domestic well-known soybean processing leading enterprises such as Laoganma, Haitian Soy Sauce and Jiu San Grease, and exported to Japan, South Korea, Taiwan, etc. The “Guangshi” brand red soybeans and green soybeans, which are independently cultivated by the state and the region, are in short supply in the market. The person in charge of the Plantation Management Department of the Ministry of Agriculture introduced that the purpose of developing the soybean industry in China is not to pursue the level of soybean self-sufficiency, nor to compete with imported soybeans, but to form a pattern of competition between domestic soybeans and imported soybeans. Imported soybeans mainly supplement the gap between edible vegetable oil and feed protein; domestic soybeans are mainly used to make traditional soy products and seasonings. The most stringent seed management was implemented, and one genetically modified soybean seed was not allowed to enter Keshan to ensure the purity of non-GM soybeans. Implement the most stringent production management system, organize production in strict accordance with the regulations of green organic soybeans, vigorously promote the “three reductions, two increase and one increase” project, reduce pesticides, reduce fertilizers, reduce herbicides, increase organic fertilizers, increase mechanical operations, and adopt Biotechnology kills insects, ensuring that Keshan non-GMO soybeans are green, organic, safe, safe, delicious and nutritious. In addition, accelerate the implementation of advanced soybean eco-efficient production and assembly technology and improve the quality and safety supervision and traceability system. It is understood that starting from 2015, Keshan County invested 19 million yuan to introduce "Internet of Things +" and "Internet +" technology. This year, 67,000 mu of "Internet of Things +" high-standard model base was established, and e-commerce entrepreneurship was established. The park has developed e-commerce products such as Renfa Green Manor Soybean Bean, which allows Keshan non-GMO soybeans to receive consumer experience supervision from planting to processing and sales.
