摘　　要：探讨了免耕秸秆覆盖机械化栽培对夏玉米外部性状、环境状况和产量性状的影响,并与6种栽培模式进行了田间对比试验.结果表明,免耕秸秆覆盖机械化种植模式有助于作物生长,土壤蓄水保墒,提高水分利用率,改善作物生长环境条件,提高玉米产量.Studies were carried out on the effect of the mechanization cultivating technology of notillage driling with mulching on the external properties,environmental conditions,and yield propertyies of summer corn.Field experiments were conducted to compare it with 6 cultiuating models.The results show that the mechanization cultivating model of notillage drilling with mulching can promote the robust growth of plants,conserve soil moisture,raise water use efficiency,improve the environmental aonditions for plant growth,and increase the yield of corn.
