【目的】采取浅埋秸秆隔层方式，抑制江苏滨海盐碱土急剧返盐，促进作物生长及增产，实现盐碱土改良、秸秆资源化利用和农业高效生产。【方法】利用番茄盆栽试验，在土表以下17 cm处布设秸秆隔层，设置不同上下层土壤含盐量（1∶1、2∶4、1∶5、3∶3），研究浅埋秸秆隔层对江苏滨海盐碱土水盐运移的影响，探究浅埋秸秆隔层条件下番茄的生长情况及生理响应特征。【结果】①浅埋秸秆隔层显著减少土壤水分消耗5.7%~15.0%；增强上层土壤灌溉淋洗作用，上层土壤含盐量的降幅较无隔层处理高出9.6%~24.5%；抑制下层土壤返盐，下层土壤含盐量的涨幅较无隔层处理低于36.1%~155.0%。②浅埋秸秆隔层处理的上层根系分布数量明显增加，根质量密度分别显著升高了31.7%~40.0%，根长密度大幅升高了20.6%~3...
