中文摘要：
基于田间试验，分析了持续微咸水膜下滴灌下棉田土壤盐分的累积规律。结果表明，土壤盐分随湿润锋而移动，以宽行（滴头下）表现最明显，但水分的再分布对盐分分布影响相对较小；浅层盐分分布状态实质上是水分入渗和蒸发相互竞争的结果。为使积盐层面不停留在棉花根系最发育范围，应根据不同时期棉花根系的分布，对土壤水盐进行调控。
英文摘要：
Field experiments were conducted to analyze the accumulation characteristic of soil salt in cotton field under mulched drip irrigation with brackish water. The results showed that soil salinity moved with wetting front, especially the wide row below the drip emitter, but the effects of soil moisture redistribution on soil salt distribution were relatively smaller; moisture infiltration and evapotranspiration affected the shallow salt distribution together in essence. To avoid the salt accumulation in the range of cotton root development, soil water and salt should be regulated according to the root distribution during different stages of cotton.
