上层土壤 meaning in Chinese
upper layer of soil
Examples
- Clay has large soil moisture because of it ' s strong capacity
而粘土有较强持水力，上层土壤湿度大。 - The results were as follows : 1 . on the basis of saline water infiltration , the characteristics of movement of soil water and salt under different cumulative infiltration were studied . the results indicated that when the salinity of the infiltration water was 3g / l , the top soil was desalinized and salt accumulated at the wetting front
通过对不同入渗水量下土壤水盐运移规律的室内模拟试验研究，结果表明利用矿化度为3g l水入渗后，土壤从上至下逐渐脱盐，上层土壤含盐量略低于土壤初始含盐量，中间土层基本保持土壤初始含盐量值，但湿润锋附近发生突变，含盐量达最大值。
