Abstract Background Intercropping, especially with legumes, as a productive and sustainable system, can promote plants growth improves the soil quality than sole crop, is an essential cultivation pattern in modern agricultural systems. However, metabolic changes of secondary metabolites tea during processing intercropping soybean have not been fully analyzed. Results The metabolomic were significant influence different stages. Especially profuse flowering stage soybean, biosynthesis amino acids was significantly impacted, flavonoid biosynthesis, flavone flavonol also changed. And expression associated metabolism, particularly glutamate, glutamine, lysine arginine up-regulated, while sucrose D-Glucose-6P down-regulated. Furthermore, chlorophyll photosynthetic parameters activity higher plants-soybean system. Conclusions These results strengthen our understanding mechanisms plant’s under system demonstrate that leguminous crops greatly potential to improve quality. may provide basis for reducing application nitrogen fertilizer ecosystem plantations.
