It can be used for improving sodic soils , at the same time the content of salt in the soil is increased because of exerting bfgd .

可以用来改良碱化土壤，但施加脱硫石膏同时也增加了土壤中的盐分含量。

The experimental results indicated that the lateral movement of saline and sodic groundwater and its evaporation resulted in a significant difference of salt and sodicity distribution between the north and south parts of the experimental plot .

试验结果显示，高盐碱地下水的侧向运动和蒸发形成了试验田南半部和北半部土壤中盐碱度分布的巨大差异。
