This article summarized the strip intercropping technology of soybeans and corn from the aspects of pre-sowing preparation, sowing management, and field management. In production, fields with deep soil layers and convenient irrigation and drainage should be selected, with wheat or potatoes as the preferred preceding crops. Base fertilizers were primarily organic, accounting for 70% of the total fertilizer application. For maize, varieties such as Longping 206, characterized by high density tolerance and lodging resistance, were chosen. For soybean, shade-tolerant and highly adaptable varieties such as Zhonghuang 37 were selected to ensure matched growth periods and adaptation to local light and heat resources. Regarding sowing, the optimal time was determined to be from mid-April to early May when the ground temperature had stably reached 10 ℃. A compound pattern of 4 rows of soybean and 2 rows of maize was adopted, and mechanical or manual sowing was used to ensure proper depth and spacing. After sowing, timely seedling checks and replanting were conducted, and water management and pre-emergence herbicide application were carefully performed to ensure uniform seedling emergence. Field management was carried out with stage-specific precision operations. During the seedling stage, attention was paid to thinning and fixing seedlings, intertillage weeding, and targeted fertilization to ensure root development. In the mid-growth stage, heavy applications of panicle fertilizer for maize and flowering fertilizer for soybean were emphasized, along with enhanced water supply. Integrated pest management was implemented using appropriate pesticides to control pests such as corn borers and pod borers, while chemical control techniques were used to prevent excessive growth and lodging. In the late growth stage, timely foliar fertilization and moisture retention and drainage prevention were carried out, and harvesting was done promptly based on the maturity characteristics of the grains. This paper provides a reference for the extension of the soybean and maize strip intercropping model.
