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;可提高水分利用率及土壤的生物活性,明显地调节作物生长的水、肥、气、热等生态条件,促进小麦的生长发育,明显提高小麦的产量,增产可达到28.23%.The main test studies the influence of the mulching straw on growth and yield of winter wheat in the east of China where harvested twice in a year. Experiments show that： straw mulch improves the soil physical and chemical properties, increase soil nutrient availability and water use efficiency,enhances the biological activity of soil, significantly adjusts the water, fertilizer, gas, heat and other ecological conditions for crop growth, promotes the growth of wheat and increaes wheat yields, increased for 28.23 percent can be achieved.

关 键 词：秸秆覆盖 土壤温度 水分含量 小麦产量
