| 摘 要： | 通过对试验地覆盖不同量的玉米秸秆,采用TRIME土壤水分仪,分别研究不同覆盖条件下麦地土壤水分变化特征和不同处理条件下腾发量随时间的变化特征。结果表明,秸秆覆盖是减少棵间无效水分蒸发,提高根层土壤含水量及水分利用效率的有效途径,具有明显的保水保墒效果,因此,在半干旱地区采用秸秆覆盖技术是促进农业可持续发展的有效措施之一。

| Abstract: | By using TRIME soil moisture meter,the change feature on soil moisture of the grain field under different mulching conditions and quatity of Tengfa with the changes of time characteristics under different processing conditions is studied.The test results show that：Straw mulching is an effective way to reduce the invalid evaporation of water between straws and to improve the soil water content of the roots and water use efficiency;The water has obvious effect on moisture,so straw mulching is one of the effective measures to promote sustainable development of agricultural technology in the semi-arid areas. |
