The shading of maize and self-shading are the key factors affecting stem lignin biosynthesis lodging resistance soybean at middle later growth stages in strip intercropping system. A study was designed to explore regulation mechanism metabolism different planting densities; PD1, PD2, PD3 were used having a total number 17 plants m−2, 20 25 respectively, on intercropped stem. Our results depicted that lower density (PD1) appropriately promoted leaf photosynthesis activities (Pn), increase activity lignin-related enzymes accumulation carbohydrates stems, eventually enhanced Correlation analysis also showed index significantly correlated with available light for canopy Pn characteristics related synthesis among densities. findings our research will be useful future studies understand relationship between environment, densities, guide optimum maize–soybean
