【目的】探讨积水入渗条件下矿化度对酸性红壤水盐运移特征的影响,为我国南方非常规水合理利用提供参考。【方法】采取土柱入渗试验,以蒸馏水灌溉(CK)为对照,探究不同矿化度水(1、2、3、5、10 g/L)入渗下南方红壤水分动态运移、水盐分布及土壤pH值变化,并量化矿化度与入渗模型参数关系。【结果】与CK相比,1~10 g/L处理抑制红壤水分入渗,同一时刻累积入渗量表现为CK>1 g/L处理>5 g/L处理>2 g/L处理>3 g/L处理>10 g/L处理。5 g/L处理持水能力显著高于其他处理(p<0.05),单位时间湿润锋运移距离小于CK和1、2 g/L处理。Kostiakov公式较Philip方程能更精确描述1~3 g/L处理红壤累积入渗量随时间变化,矿化度大于3 g/L时则相反。红壤累积入...
