摘要

通过分析6种不同耕作措施对定西半干旱地区春小麦土壤水分年变化和垂直变化的影响

结合春小麦产量分析了不同耕作措施的水分利用率。结果表明

免耕秸秆覆盖和传统耕作秸秆覆盖两个处理土壤贮水量少

但水分利用效率高。而免耕不覆盖和免耕覆膜2个处理土壤贮水量最多

但作物的水分利用率最低。从不同耕作措施对土壤贮水量的影响看

表现为TW6>TW3>TW1>TW5>TW2>TW4

而水分利用率则为TW2>TW4>TW1>TW5>TW3>TW6。

Abstract

According to analysis six tillage methods how to effect Dingxi semi-arid area spring wheat soil water annual change and vertical change and water use efficiency.Result shown no-tillage and traditional tillage treatments had little water storage but higher water use efficiency.No-tillage with out mulch and no-tillage mulch treatments had more water storage but lower water use efficiency.From the effects of different tillage methods to soil water storage

TW_6>TW_3>TW_1>TW_5>TW_2>TW_4

water use efficiency TW_2>TW_4>TW_1>TW_5>TW_3>TW_6.
