In response to the problems of fragmented mountainous farmland and low light energy utilization rate, this paper conducted field experiments using the soybean-maize strip intercropping method as the research object. It compared the yield differences among different planting patterns, density configurations, and variety combinations, analyzed the mechanism of increasing yield through appropriate variety combinations adapted to mountainous environments, and selected the optimal variety combination scheme and field configuration system suitable for the mountainous areas of Southwest China. This provided theoretical support and practical basis for the selection of superior varieties, improvement of quality and efficiency, and the large-scale promotion of technology for strip intercropping in mountainous areas.
