Soybean is a ternary crop of grain, economy and feed. It is an important raw material for the development of animal husbandry and food industry. It is of great significance for increasing grain production, increasing farmers' income, improving food structure, and improving living standards. The winter soybean has a long growth period, strong resistance at the seedling stage, sowing in early summer, and a prosperous growing season in the months of corn harvesting in August, September and October. The symbiosis with corn is not prominent. Intercropping winter soybeans in corn fields does not occupy cultivated land and there is no conflict between soybean production and other crops. Without affecting corn production, 30-50 kilograms of soybean production can be increased per acre. At the same time, soybean rhizobium and a large number of vine leaves are also beneficial to improve soil fertility, with significant economic and social benefits. The technical points are as follows: 1. Popularize thoroughbreds and plant them properly. The preferred vertical growth, resistance to lodging, shade resistance, resistance to fertilization are good tribute to the No. 1; followed by the choice of semi-simple Weiyuan small winter beans. Intercropping spring maize for winter soybeans was best sown around April 20. 2, rational close planting, increase phosphate fertilizer. The type of spring “Jade, wolfberry, and bean†was used to make three crops of spring, one nest of soybeans was used to make one nest of winter soybeans between two litters, and two crops of corn were used to make one litter of winter soybeans between two litters, and two to three seeds were planted in each litter to make them intercropping. 1100 litters of winter soybeans, about 3000 seedlings. The planting method is that the winter soybean seed is better in the narrow inner row of the corn, and the 15 kg of the phosphoric fertilizer is mixed with the grass ash, and covered with the mature fertilizer. 3, according to local conditions, reasonable layout. Winter soybeans are generally planted in low-level drylands and troughs in order to avoid harm to rabbits. 4. Strengthen field management to ensure strong seedlings. (1) 1 to 2 true leaves of winter soybeans are spread out. Timely seedling reseeding to ensure full seedlings; (2) Using paclobutrazol and chlorhexidine to control winter soybeans in the compound leaves stage of 5-8; (3) From flowering to crusting stage, aphids, bean beetles, and soybean meal are more harmful and can be controlled by organic phosphorus insecticides.
