Based on the theory for water movement in non-saturated soil, the mathematical model of film hole irrigation was developed to describe soil water movement of the film hole irrigation. The SWMS—3D software was used to solve the model and the results were testified with laboratory experiments. The numerical simulation values are coincided with the experimental values, which show that the model is credible. Finally, the affects of irrigation water technologies elements on the soil wetting pattern, film hole infiltration volume of film hole irrigation were simulated and analyzed. The results indicate that the soil character, bulk density, initial water content, film hole diameter and irrigation water depth have slight effects on the wetting pattern, and the film hole space have obvious effects on the soil water contribution near the film hole when the film hole space is large. The soil character and bulk density have obvious effects on water infiltration characters. Meanwhile, initial water content and irrigated water depth have slight effects on water infiltration characters. The average infiltration water depth of film hole control zone with infiltration time is mainly affected by open hole ratio and film hole diameter.
