生产实践证明,玉米与小麦实行间套作,可以获得增产。目前,这种栽培方法已成为我省玉米、小麦产区的一种重要栽培形式。但是,有不少地块实行米麦间作后玉米比清种时减了产,总产量低于清种时的产量。 Production practice has proved that the intercropping of corn and wheat can be increased. At present, this cultivation method has become an important form of cultivation of corn and wheat producing areas in our province. However, after many plots of maize intercropping were conducted, the yield of maize was reduced compared with that of the purebreds and the total output was lower than that of the cleared ones.
