摘要
通过大量膜孔多点源交汇入渗试验资料 ,分析了膜孔多点源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多点源膜孔交汇入渗的影响 ,提出了各影响因素与膜孔交汇入渗量和交汇时间的关系 ,并分析了膜孔交汇入渗机理。
Through test, characteristic and influential factors of multiple point sources interference infiltration are analyzed. The main influential factors such as size of film hole, space of film hole, soil texture, soil bulk density and initial soil moisture content were researched. The relationships between each influential factor and film hole interference infiltration volume and interference time were put forward respectively. Mechanisms of film hole interference infiltration were analyzed. The research results may offer reference for further research of multiple point sources interference infiltration law and film hole irrigation.
