摘要
通过大量膜孔多向交汇入渗试验资料,分析了膜孔多向交汇入渗特性和影响因素,研究了膜孔直径、膜孔间距、土壤质地、土壤容重和土壤初始含水率等因素对膜孔多向交汇入渗的影响,提出了各影响因素与膜孔交汇入渗量之间的关系,并分析了膜孔多向交汇入渗机理,该研究成果可为进一步研究膜孔交汇入渗规律和膜孔灌技术提供参考。
Through test, characteristic and influential factors of film hole bilateral interference infiltration are analyzed. The main influential factors such as size of film hole, soil texture, soil bulk density and initial soil moisture content were researched. The relationships between each influential factor and infiltration volume were put forward respectively. The mechanisms of film hole interference infiltration were analyzed. The research results may offer reference for further research of film hole interference infiltration law and film hole irrigation.
