通过室内入渗试验，分析了膜孔肥液多向交汇入渗特性，在此基础上，提出了4个膜孔肥液多向交汇入渗模型。减渗量模型建立在膜孔肥液自由入渗参数和减渗量参数已知的条件下，分段函数模型建立在膜孔肥液多向交汇入渗各阶段入渗模型均为幂函数的条件下，增渗率模型建立在膜孔肥液多向交汇入渗相对膜孔清水多向交汇入渗增渗率和清水入渗参数已知的条件下，减渗率模型建立在膜孔肥液单向交汇入渗相对膜孔肥液自由入渗的减渗率、膜孔肥液多向交汇入渗相对膜孔肥液单向交汇入渗的减渗率和膜孔肥液自由入渗参数已知的条件下。经实测资料验证，所提出的4个模型计算精度均较高。

Based on the lab experiment,has analyzed the infiltration characteristics and put forward the four mathe-matical models for the fertilizer solution bilaterally flowing into the film hole .The reducing infiltration model was set up under the conditions that the free infiltration parameters and the reducing infiltration parameters of fertilizer solution flow-ing into film hole has been known .The piecewise function model was set up under the conditions that the infiltration model in each stage was total for the power function .The increasing infiltration ratio model was set up under the condi-tions of increasing infiltration rate that compared the fertilizer solution with the fresh water bilaterally flowing into film hole and the parameters of fresh water bilaterally flowing into film hole has been known .The reduction infiltration ratio model was set up under the condition of reducing infiltration rate compared the fertilizer solution single-line infiltrated into film hole with the fertilizer solution free infiltrated into film hole and the parameters of free infiltrationhas been known .These four models can be supplied rather accurate canculation results through the measured data .
