| This thesis is armed at the technique of film hole irrigation which need solved immediately in Ningxia Diversion Yellow River irrigation Area , and the paper depends on water-saving irrigation experiment filed at the measure the pit of Ningxia Univercity , adopts orthogonal test design and infliltration experimental , takes technique of water-saving irrigation , computer and mathematical statistics , soil water movement as research measures . The infiltration, behaviors of surface water flow motion data of film hole irrigation were analysed. The best fitting of the irrigation system of film hole irrigation and the deepness of water table were systematically research on in this thesis. The research results were as followed:1. The research situation of film hole irrigation technique and the research situation of soil water, caloric and salt movement were summed up.2. Through the infiltration filed experimental data , the formula of film hole irrigation are found , h=57. 676t0.6691, v=38. 591t-0.3309.3 Under the same condition, the irrigation, times of irrigate, the deepness of water table are select ax experiment factor , the different system of irrigation which effected the yield and physiological indexes on maize were systematically analyzed . And last the best fitting of water irrigation system and the table were found Irrigation requirement is 55m3/667m2, irrigation times is 3, the deepness of water is 0.9m.4. This paper, based on theory of soil water dynamics, established soil hydraulic properties with lever of pillar, one-dimension condition soil water movement model were established. Programs were made to get the numerical solution by Matlab software.showed that of numerical simulation of model were in good agreement with the measured filed data of experiment. According to the above research, the infiltration models were reliable and provided a reliable foundation for the evaluation of water resource in the area of Ningxia.
