- 摘要：以天津东郊污灌区(慢速渗滤系统)为试验点,总结了土壤盐分的变化规律,并以粮地、菜地、稻地为代表分析了土壤中盐分变化动态,用污灌区土壤盐分动态平衡公式CK-Ch=CB-CO测算,结果表明,只要灌区排水条件好,加上合理的科学灌溉,污灌区土壤盐分变化趋势是脱盐占主导地位,土壤中的钠吸附比(SAR)有所改善,土壤质量有所提高.
- Abstract：The study was carried out in east suburb at Tianjin during theperiod of 1988-1989. The variation in a slow rate infiltration system of sewage irrigation area was summed up. Meanwhile, according to the results of analysis, the dynamic variations of soil salinity in crop field (corn-wheat), vegetable field (eggplant-chinese cabbage) and rice field, and the continuous monitoring, the dynamic balanced formula of soil salinity in sewage irrigation area is CK-Ch = CB-Co. The eventual result is: if the condition of drainage is good and irrigation is reasonable, the variation trends of soil salinity would be desalted. Moreover, the SAR of soil and the soil quality are improved.
