| 摘 要： | 玉米秸秆覆盖冬小麦田后，冬季和早春季节对土壤温度有明显的增温作用，有利于保护小麦安全越冬，春季则有降温作用，影响春季小麦的分蘖和生长，覆盖处理能有效地抑制土壤无效蒸发，提高麦田的水分利用率；覆盖量为3000kg/hm^2时，有增产作用，覆盖量为6000kg/hm^2，有一定的减产作用。

| Abstract: | The field experiments on soil temperature and soil water dynamics in the wheat field mulched with maize straw were conducted The results show that the soil temperature and humidity in wheat field would increase in winter and early spring By mulching with maize straw it could be safe for overwintering of winter wheat, and however, the growth and tillering of winter wheat in spring would be restrained Since the soil evaporation was restrained effectively, the water efficiency could increase The yields of winter wheat would increase when the fields were mulched with 3000kg/hm 2 maize straw; but the yields of winter wheat would decrease when the fields were mulched with 6000kg/hm 2 maize straw |
