摘　　要：研究经不同方式处理的秸秆还田后对玉米生育期及生长性状的影响情况。结果表明:秸秆深施还田能够缩短玉米生长发育周期、提高玉米出苗率及促进玉米生长发育。在玉米生长前期,秸秆粉碎程度越大,对作物生长发育的促进作用越明显;到中后期,其他处理也显示出明显的作用。The article expounds the research on the influence to maize breeding period and growth properties after using different treat-ments to straw and returning to the field. The result shows that straw deep buried can shorten maize growth period, increasing emergence rate of maize and promoting the growth of maize. In prophase of maize growth, the more crushing to straw, the better promoting growth function to crops;in middle and late period, other treatments also show obvious helpful functions.
