| 摘 要： | 为了探究客土改良方法对碱土理化性质的改善作用,采用室内模拟实验分析了沙土和黑土添加量对碱土饱和导水率和盐分淋洗的影响。结果表明：碱土饱和导水率与沙土或黑土添加量间存在极显著的线性关系,饱和导水率随沙土或黑土添加量逐渐增加而不断升高;碱土盐分淋洗效果随沙土或黑土用量的增加而增强,淋洗液电导率和pH随客土添加量的增加而降低;碱土淋洗液的电导率和pH随饱和导水率的升高而降低,淋洗液电导率和pH与饱和导水率间分别呈线性和幂函数关系。

| Abstract: | Bases on simulation experiments in laboratory,the effects of the amount of additional soil on saturated hydraulic conductivity(K10) of sodic soil,electrical conductivity(EC) and pH of leachates were investigated,and relationships between K10 and EC of leachates,K10 and pH of leachates were established.Results showed that K10 increases with the increments of additional soil amounts,and the relationships between them follow linear functions significantly;values of EC and pH of leachates decrease with the incr... |
