Abstract: 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.
