在不同的盐浓度下，测定了沿着填充有蒙脱石、蛭石和高岭石土壤的土柱的水力电导率和梯度，这些土壤调整为不同的交换性Na水平。分散的粘土颗粒堵塞孔隙显然是用钠离子水灌溉的表层土壤导水率降低的主要原因。
The hydraulic conductivities and gradients along soil columns packed with montmorillonitic, vermiculitic and kaolinitic soils adjusted to different levels of exchangeable Na were determined at different salt concentrations. Plugging of pores by dispersed clay particles apparently is a major cause of reduced soil hydraulic conductivity for surface soils irrigated with sodic waters.
