摘要
用压力排水法对氯化钠、氯化钙和碳酸氢钠盐渍土的持水特性进行了测定,结果表明,无论是氯盐土还是碳酸盐土其土水势绝对值都随含液量的减少而增大,同类盐渍土在含液量相同的情况下,土水势绝对值是随土壤溶液摩尔浓度增大而增大,并有很好的线性关系。
Saline-alkaline'soil water retention curves were measured by a pressure drainage method. The results showed that the saline- alkaline soil water potential absolute value will be increased with the content of soil liquid decrease; the same kind soil Of water potential absolute value will be increased with the increase of concentration of soil liquid.
