摘要

干旱缺水是元谋干热河谷旱坡地粮食产量提高的主要制约因素。为了充分利用雨季旱坡地的壤中流

缓解季节性干旱。 1999年

在元谋县的旱坡耕地上进行了“地下地膜隔水墙”试验

试验结果表明

布设地下地膜隔水墙的旱地比对照小区增产7.1%～20.2%。

Abstract

Dry and water shortage are the main restrict factor for grain output increasment of non-irrigated slope field in Yuanmou dry and hot valley. In order to utilize soil through-flow moisture fully and reduce seasonal drought

the underg round plastic sheet wall experiment in the non-irrigated slope field in Yuanmou county was carried out in 1999. The result indicates

that the output of the non-irrigated slope field with underground plastic sheet wall is increased by 7. 1%～ 20. 2% compared with the cont rast area.
