摘　　要：利用适宜株型玉米和矮秆大豆进行玉米-大豆带状间作有利于农业的可持续发展。探索玉米不减产或减产5%以内,且额外增收大豆1 000kg/hm2的间作组合,选择适合间作的玉米品种是构建优异玉米-大豆间作复合群体技术的核心之一。对2∶2玉米-大豆带状间作的玉米产量和农艺性状进行初探,初步了解了间作模式对玉米产量和农艺性状的影响规律,初步筛选出适宜本地区间作的玉米品种,为本地区示范、推广该模式提供理论依据。Maize and soybean strip intercropping with suitable plant type of maize and dwarf soybean is conducive to agricultural sustainable development. One of the key techniques of building excellent composite populations of maize and soybean intercropping is to select maize varieties suitable for intercropping, keeping yield no reduction or decrease less than 5 % , and having an extra soybean intercropping combination of 1 000kg/hm2. The result indicated the changes of the yield and agronomic characters of maize in 2：2 intercropping. This research provided theoretical and practical basis for choosing the suitable planting patterns and cultivars.
