    摘要:

    根据田间排水地段实测的土壤含盐量与地下水埋深和矿化度,分析了土壤盐分组成变化特征以及覆膜种植对抑制土壤积盐的效应.根据潜水蒸发特点,确定了建立地下水埋深与土壤含盐量间单一函数关系的方法,为根据土壤含盐量确定地下水临界深度提供指导.

    Abstract:

    According to measured soil salt content, groundwater table and degree of mineralization features of component of soil salt was analyzed and effect of the film laid on soil surface on salt transport from groundwater to soil surface was studied. A simple function relationship between groundwater table and soil salt content was established to provide a method of determining groundwater critical depth, considering the effect of mineralization deeree of eroundwater
