1·The increase in initial soil salt content would decrease the desalinization coefficient.
土壤初始含盐量的增加使得达标脱盐系数减小。
2·With the massive groundwater pumped for irrigation, there was an apparent decrease of groundwater depth and desalinization in soil layers that led to a substantial increase of crop production.
井灌井排技术有效地降低了地下水位，土壤明显脱盐，作物产量不断提高。
3·Moreover, the soil salinization can be controlled by combining the engineering with biological measures, the desalinization rate can be up to 42.8% by pumping groundwater to replace drainage;
同时，基于水资源合理利用的土壤盐渍化防治可采取工程和生物相结合的措施，采用竖井以灌代排可使区域内平均脱盐率达4 2 .8% ；
