摘要

通过模拟降雨对定西苜蓿-春小麦轮作土壤的水蚀过程进行了研究，试验结果表明：苜蓿翻耕（T1）处理的地面积水产生时间最长，苜蓿不翻耕处理（T2）径流产生时间最长，显著高于其它3个处理。在整个模拟降雨过程中，不翻耕处理的径流产生速率总是低于翻耕处理的径流产生速率，其中以苜蓿不翻耕处理（T2）的径流速率最小，而两个翻耕处理的径流速率之间无显著性差异。T2处理的入渗速率始终高于其他3个处理；秸秆覆盖可有效地降低累积径流量和总侵蚀量，增加累积入渗量；在不同处理中，以苜蓿不翻耕处理加100％秸秆覆盖抗水蚀的效果比较明显。

Abstract

In this paper

soil water erosion of lucerne-spring wheat rotation soil in Dingxi under has been studied.The results showed that Pounding time of lucerne field with till(T1) is the longest.Runoff time of lucerne field with no till(T2) was the longest

which was significantly higher than three treatments.In the whole process of rainfall simulation

the runoff velocity of no till was lower than that of tilled.In four treatments

the runoff velocity of lucerne field with no till(T2) was the lowest

but between two tilled treatments had not significant difference.The infiltration velocity of lucerne field with no till(T2) was higher than that of other three treatments.Straw covering could decreased cumulated runoff and sediment and increased infiltration in the same time.In the different treatments

the result of resist water erosion of lucerne field with no till(T2) and 100% straw cover was obvious.
