摘要(Abstract)：

为了探究灌水频率与生物炭施用对滨海盐渍土水盐运移特征的调控效应，采用室内土柱模拟试验，以滨海盐渍土为供试土壤，在土壤表层(深度为0～20 cm)设置不同的生物炭施用量和灌水频率，组合成9个处理方案，研究灌水频率对生物炭改良盐渍土水盐运移的影响。结果表明：生物炭能提高单次灌水入渗速率，有效缩短累积水分入渗时间，提高表层土壤含水率，并能使土壤容重减小，表层土壤pH有所增加；当灌水频率为中频时，表层土壤含水率增加14.17～18.87个百分点，表层土壤脱盐率为66.39%～86.31%,脱盐深度相对更深；当灌水频率为低频、中频时，施用一定量的生物炭有利于土壤盐分淋洗，表层土壤脱盐率提高9.99～15.62个百分点；每8 d灌水1次的灌水频率和生物炭施用量为5 g/kg的处理方案能够显著改善滨海盐渍土的水盐分布。
