| 摘 要： | 以燃煤电厂脱硫石膏为试材,采用土柱模拟试验方法,研究不同灌水量下脱硫石膏对盐碱土壤盐分运移的影响,以期探究脱硫石膏最佳淋洗灌水量。结果表明:不同灌水量下0～20cm土层Na^+含量均呈降低的趋势,灌水量为田间持水量85%(T85%)在各层土壤pH、碱化度、电导率、Na^+含量均最低。施加脱硫石膏后0～20cm土层Ca2+增加,不同灌水量下Ca2+含量整体表现为T85%

| Abstract: | The effect of desulphurized gypsum from coal-fired power plant on salt transport in salinealkali soil under different irrigation amount were researched by soil column simulation test,in order to explore desulphurization gypsum best rinse irrigation water.The results showed that the content of Na^+ in 0-20 cm soil layer decreased under different irrigation amount,and the pH,alkalinity,conductivity and Na+ content in each layer were the lowest when the irrigation amount was 85% of field capacity(T85%).Ca^2+ content in 0-20 cm soil layer increased after applying desulfurization gypsum,and the overall Ca^2+ content was T85%
