Multiple planting of soybeans after wheat harvest can fully utilize the remaining light, hot, and water resources after wheat harvest, achieve two crop intercropping in one year. The planting practice was combined of wheat and soybean in Shangluo, Shaanxi Province, the light, simple, and efficient cultivation techniques for winter wheat and high yield cultivation techniques for multiple cropping of soybeans were summarized and analyzed, at the same time, corresponding yield improvement strategies were proposed by focusing on the key aspects of intercropping soybeans after wheat. The cultivation techniques for light, simple, and efficient winter wheat include selecting high quality, high yielding, disease resistant, and early maturing wheat varieties; before sowing, rotary tiller and rake flat, and apply appropriate amount of base fertilizer; reasonably determine the broadcasting schedule and quantity; check and supplement seedlings, and timely carry out “one spray and three prevention” measures; timely harvest and clean up residual debris. The high yield cultivation techniques for multiple cropping of soybean varieties include selecting early maturing varieties with strong stress resistance and high and stable yield; plow and weed before sowing, and apply appropriate amount of base fertilizer; timely sowing of moisture and reasonable planting density; combining tillage weeding with chemical weeding, applying fertilizer while the soil is moist, and implementing rational control measures; seize the critical window period for disease and pest control and implement comprehensive prevention and control measures; remove from drying and store in the warehouse. The key points to focus on in the research area for wheat multiple cropping soybean include wheat harvest period, planting efficiency, soil preparation quality, and mechanization level. Therefore, reasonable crop rotation and good crop rotation connection were proposed; promote high yield cultivation techniques, and improve planting efficiency; strategies include fine soil preparation, improving soil fertility, introducing new machinery, and expanding the area of intercropping. This article provides a reference for achieving high yields by multiple cropping soybeans after wheat in Shangluo and related areas.
