摘　　要：研究了"黄淮海"一年两熟地区秸秆覆盖对冬小麦的生长发育和产量性状及其构成要素的影响。试验表明:秸秆覆盖可以改善土壤的理化性状,增加土壤养分有效性,可提高水分利用率,提高土壤的生物活性,明显地调节作物生长的水、肥、气、热等生态条件,促进了小麦的生长发育,可以明显提高小麦的产量。未进行秸秆覆盖的处理产量为4617.93kg/hm2;进行秸秆覆盖的处理,小麦平均产量最高可达到5360.00kg/hm2,提高了1303.67kg/hm2,增产可达到28.23%。The main test studies that the influence of the mulching straw on growth yield of winter wheat in the east of china where harvested twice in a year. Experiments show that：straw mulch to improve the soil physical and chemical properties Increased soil nutrient availability,water use efficiency can be improved to enhance the biological activity of soil,crop growth significantly adjust the water,fertilizer,gas,heat and other ecological conditions,and promote the growth of wheat,wheat could increase yields No straw mulch processing output 4617.93 kg/hm2,straw covered with the highest average yield of wheat can be reached 5360.00 kg/hm2,raising 1303.67 kg/hm2,an increase of 28.23 percent can be achieved. Significantly increase production results.
