摘　　要：对小麦机械收获后残茬覆盖与不覆盖两种条件下免耕、翻耕和间隔深松三种土壤耕作方式夏玉米的营养生长及籽粒产量进行了研究。结果表明,残茬覆盖和深松耕作玉米播种后出苗率高,次生根条数多,株高增加而基部节间缩短,叶面积系数提高,最终产量显著高于其他处理。The growth and grain yield of summer maize in three kinds tillage management of no tillage, moldboard plowing and sub-soiling under two conditions of stubble mulch and no mulch have been conducted. The results show that in stubble mulch and sub-soiling treatments the rate of emergence is higher, the second root is more and the plant is higher while the basal internodes is shorter. And it could increase the leaf area index and the grain yield finally.
