Abstract：The technology of soybean-maize strip intercropping plays an important role in improving soybean production and resolving the conflict between grain and oil for land.We examined the effects of changes in row ratio of soybean to maize(4S2M,4S4M,6S2M and 6S4M)on plant morphology,crop yield and overall economic benefits,aiming to provide theoretical support for strip intercropping pattern and maize variety selection in Jiangsu Province.The results showed that the changes of soybean and maize strip intercropping pattern did not significantly affect the maize morphological characteristics,but affected the yield per panicle by influencing the parameters of corn ears.The model of 4S4M had the highest gross economic benefits while the model of 6S2M had the lowest gross economic benefits,and the maize variety Qianyu 180 could highlight the advantages of the 4S4M model(for example,its gross economic income can reach 2 144 yuan/667 m2).Therefore,the combination of corn variety Qianyu 180 and 4S4M model in northern Jiangsu Province can produce higher economic benefits.
