【目的】探究微塑料对滴灌条件下不同盐分盐渍土水盐分布的影响。【方法】采用长方体（长×宽×高为30 cm×30 cm×40 cm）土槽以马氏瓶作为稳压滴灌水源，采用转子流量计设置流量为0.36 L/h进行室内土槽入渗模拟的方法，阐明了2%丰度聚丙烯（Polypropylene, PP）微塑料对不同含盐量盐渍土（0.5%、4%、7%）水平及垂直方向水分入渗后土壤水分、盐分运移及pH值的影响。【结果】入渗后土壤含水率与初始含盐量正相关，含盐量为7.0%的盐渍土处理较4.0%和0.5%的盐渍土处理平均含水率分别增加9.4%和11.2%（P<0.05）；在含盐量为0.5%、4.0%和7.0%条件下，赋存PP微塑料处理较未赋存微塑料处理在垂直距入渗点源16.6 cm位置含水率分别增加7.8%、9.4%和...
