摘 要:以夏玉米登海605及冬小麦良星66为试验材料,研究冬小麦不同秸秆还田方式对夏玉米产量的影响。结果表明,冬小麦不同秸秆还田方式均可提高土壤肥力,增加土壤有机质、磷、钾及微量元素的含量。不同秸秆还田方式的夏玉米产量为过腹还田>粉碎还田>堆沤还田>留茬还田;夏玉米的穗数为过腹还田>粉碎还田>堆沤还田>留茬还田;夏玉米的穗粒数为过腹还田>堆沤还田>粉碎还田>留茬还田;夏玉米的千粒重为堆沤还田>过腹还田>粉碎还田>留茬还田。因此,较好的秸秆还田方式为过腹还田和粉碎还田。Taking summer maize variety Denghai 605 ,winter wheat variety Liangxing66 as test material,effect on yield of summer maize of different winter wheat straw returning method were studied.The results showed that d/fferent winter wheat straw returning method could improve soil fertility ,increase the content of organic and trace elements in soil. The order of yield on summer maize in different winter wheat straw returning method was the treatment of through the intestinal tract〉the treatment of crushing straw〉the treatment of composting〉the treatment of stubble ;The order of spike number on summer maize in different winter wheat straw returning method was the treatment of through the intestinal tract 〉the treatment of crushing straw〉the treatment of composting〉the treatment of stubble ;The order of grain number on summer maize in different winter wheat straw returning method was the intestinal tract〉the treatment of composting〉the treatment of crushing straw〉the treatment of stubble ;The order of 1000-grain weight on summer maize in different winter wheat straw returning method was composting〉the treatment of through the intestinal tract〉the treatment of crushing straw〉the treatment of stubble. Therefore, suitable winter wheat straw returning method were the treatment of through the intestinal tract and the treatment of crushing straw.
