Abstract

在南方低山丘陵区,旱坡地部分土壤水以壤中流形式侧向运移,而季节性干旱发生时,往往消失。地下地膜截水墙技术即是将地膜等高垂直过去时设至下伏不透水岩层,阻断壤中流而形成土壤微型水库。在三峡库区的应用试验表明,地下地膜截水墙可有效地提高旱坡地土壤水含量,减缓季节性干旱的发生和减轻干旱造成的损失,增产效益显著(9.38%-22.40%)。

Other Abstract

In the southern hill region of China, soil moisture laterally moves downslope mostly as throughflow on dry sloping field. In order to interrupt throughflow an underground plastic sheer wall, namely a micro-underground reservoir, was built up across slope in a dry sloping field. An experiment in Wanxian, Chongqing Municipality showed that he technique was effective for reducing soil moisture losses and preventing seasonal droughts for the dry sloping field water-saving agriculture and increased crop production by 9.38%~22.40%.
