The implementation of composite planting of maize-soybean strip intercropping is an important approach for the structural adjustment of crop in the main grain producing areas of northeast China.The characteristics of light energy utilization,yield and economic output of four models of maize single（M）,soybean single（S）,maizesoybean 2∶2（M₂S₂） and 4∶4（M₄S₄） intercropping systems were compared in this study.The results showed that the photosynthetic rate,stomatal conductance,intercellular CO₂concentration and transpiration rate of intercropping maize were significantly higher than M,while those of soybean were lower than S.Corn strip intercroppingΦPSII qP,NPQ were significantly greater than M,and soybean intercropping strips were significantly lowerΦPSII,qP NPQ in S.Stripe intercropping significantly increased corn yield and decreased soybean yield in the seeding zone The compound crop yield of stripe intercropping was significantly higher than S and lower than M,but the compound economic output value was significantly higher than M and S,with the highest economic output value of M₄S₄.Both M₂S₂and M₄S₄treatment LER were greater than 1,and had intercropping advantage.
