| 摘 要： | 本文取用城市道路中央分隔带风干土壤,通过室内土柱试验,对在中水灌溉条件下不同灌水次数时土壤的水盐运移规律进行了试验研究,试验结果表明:随着灌水次数的增加,脱盐深度逐渐增加,含盐率锋值深度增加,且同一土层深度的含水率增大,累积的盐分减少。

| Abstract: | In this research, the soil water and salt transportation in the air- dried soil columns were investigated under different irrigation times on central strip of city road under middle water irrigation. The main results are:The increasing irrigation times will be increased the depth of desalinization, the depth of peak salt content. In the same soil layer, the increasing irrigation times increased the soil water, reduced the soil salt. |
