To popularize the soybean and corn strip intercropping technology in Western Yunnan, the key points of soybean and corn strip intercropping technology were introduced from the aspects of preparation before sowing, key points of sowing technology, field water and fertilizer management, crop control and topple prevention, field weeding, disease and pest control, harvest and storage. Before sowing should choose the convenient transportation, gentle terrain, conducive to irrigation of fertile soil, select a good weather for ploughing and loosening, deep ploughing 20-40 cm is appropriate; varieties with similar maturity and more synchronized growth and development are selected for planting. Sowing should be carried out in the season when the soil moisture and temperature are suitable, such as on-demand sowing and drill sowing. According to the characteristics of soybean and corn varieties, reasonable planting patterns are adopted, including 2-row corn and 2-row soybean, 2-row corn and 3-row soybean, and 2-row corn and 4-row soybean. In field water and fertilizer management, nitrogen fertilizer is the main fertilizer and phosphate fertilizer is the auxiliary fertilizer. Chemical control method is adopted to control the growth of corn and soybean. Field weeding management is carried out by chemical weeding and artificial weeding. In view of common root rot, corn borer, cotton bollworm, red fire ant and other diseases and pests of soybean and corn, comprehensive control measures such as physical control, biological pesticide control and ecological regulation are adopted. Adopt artificial or mechanical harvesting, timely harvest soybeans and corn, and timely drying, threshing, when the seed water content is less than 13%, packaging storage. This paper provides a reference for the further popularization of soybean and corn strip intercropping technology in the study area and related areas.
