Shuitu Baochi Xuebao, 2021 为探究土壤残膜量对膜孔灌肥液入渗土壤水氮运移特性的影响，通过室内土箱模拟试验设置0，90，180，360，720 kg/hm2的5个残膜量水平，分析不同残膜量下膜孔灌肥液入渗累积入渗量、湿润锋运移距离、湿润体特征和水氮分布规律。结果表明：残膜对膜孔灌肥液入渗具有阻渗作用，残膜土累积入渗量较无残膜土减少10.63%~30.77%，Kostiakov模型对残膜土单位膜孔面积累积入渗量与入渗时间有较好地拟合效果；入渗前30 min，不同残膜量的垂直湿润锋运移距离差异不显著，随着入渗时间推进 ...

Shuitu Baochi Xuebao, 2007 通过肥液间歇和连续入渗实验,分析了肥液间歇入渗土壤湿润特性。结果表明,肥液间歇入渗湿润锋运移速度较连续入渗慢,并随周期数的增加而减小;分析了肥液间歇入渗湿润锋运移的分段模型,提出了由连续入渗湿润锋运移参数计算间歇入渗湿润锋运移距离的简化模型,实例计算表明该方法简单有效;对比了肥液间歇入渗和连续入渗土壤含水量的分布,肥液间歇入渗土壤含水量分布较连续入渗均匀,相同深度土层中入渗水量占总入渗量的比例较大。
