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。 1 999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 %～ 2 0 .2 %
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 underground 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 contrast area.
