【目的】探讨不同矿化度咸水滴灌荒漠植物梭梭对土壤水盐运移特性的影响。【方法】采用测坑进行咸水滴灌梭梭试验，运用舒卡列夫和Piper三线图等方法，分析不同矿化度对梭梭土壤水分、盐分、土壤离子量和水化学特征变化。【结果】①不同矿化度咸水滴灌后，不同深度土壤盐分累积量不同，结果发现在60~80 cm深度处积盐，最高积盐量可达6.2 g/kg；且咸水滴灌梭梭土壤含盐量与灌水矿化度呈正相关关系；②咸水滴灌梭梭后，土壤中SO2- 4、Cl-、K+和Na+离子量的变化随矿化度显著增加，土壤水溶液阳离子由Ca2+逐渐向Na+变化，阴离子由SO2- 4逐渐向Cl-变化，水化学类型由SO2- 4-Ca2+?Mg2+型逐渐向SO2- 4?Cl--Na+型演化。【结论】不同矿化度滴灌梭梭条件下，分析土壤含水率、含盐...
