摘　　要：大豆玉米带状复合种植技术在提升我国大豆产能和缓解粮油争地矛盾中发挥着重要作用。通过评估带状复合种植体系中大豆玉米行比配置变化(4S2M、4S4M、6S2M、6S4M 4种模式)对玉米植株形态、作物产量和整体经济收益的影响,以期为江苏地区大豆玉米带状复合种植模式和玉米品种选择提供理论支持。结果表明:种植模式的改变不会显著影响玉米植株形态特征,但会通过改变玉米果穗相关性状参数来影响单穗产量;4S4M模式能够产生最高的平均经济毛收益,6S2M模式产生的经济毛效益最低,玉米品种迁玉180能够更加突出4S4M模式的优势,使其经济毛收益达到2144元/667 m^(2)。因此,在苏北地区选用玉米品种迁玉180与4S4M模式配套使用能够产生更高的经济效益。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 2144 yuan/667 m^(2)).Therefore,the combination of corn variety Qianyu 180 and 4S4M model in northern Jiangsu Province can produce higher economic benefits.
