| 摘 要： | 通过室内试验,建立了3种膜孔肥液自由入渗数学模型,并对各种肥液自由入渗数学模型做了比较分析后得出:Ph ilip模型能够较好的反映膜孔肥液自由入渗过程;通过膜孔肥液自由入渗湿润锋的运移规律,总结了水平方向和垂直方向湿润锋推移表达式;结合水量平衡原理推求了湿润体内平均重量含水率。以上成果为进一步研究膜孔肥液自由入渗湿润体内重量含水率和肥料的分布奠定基础。

| Abstract: | Based on the indoor experiment of the single film hole fertile solution infiltration,three mathematic models were established.The Philip model could reflect the course of film hole fertilizer solution infiltration better through comparing them.The expression of the wetting front in the level and erect direction were concluded from the transferring law of the film hole fertile solution infiltration,and the average water ratio in wetter body according to the water balance method.These researches have laid a foundation for further study of the water ratio and fertilizer distribution. |
