AbstractMaize intercropping mode was recognized asan important technical measure to address arable land constraints and enhance the land utilization.Theregulatory effects of maize intercropping with other crops including soybean on farmland ecologyand agricultural production were summarized，and key considerations for intercropping were analyzed.Through spatiotemporal niche complementarity to enhance landuse eficiency.The structure of soil microbialcommunities wasimproved （increased bacterial diversityandregulated fungal communities），thereby strengthening soil fertilityand ecological functions.Thetall maize stalks provided natural shadingforshade-preferring crops （Polygonatum sibiricum，Amorphophallus konjac），regulating micro environmental humidityand light conditions. Nutrient accumulation in crops was promoted （increased crude protein in soybeans，enhanced heavymetal enrichment in Sedum alfredii），leading to improvedquality.Suitable crop varieties were selected based on their characteristics，and field management was optimized，including rational planting density （adjusting row spacing to reduce shading effects）， improved waterand fertilizer management，and pestcontrol （utilizing crop interactions to suppress pests）.This study provided a reference for promoting the application of maize intercropping with other crops.
