Abstract:: Based on the analysis of low-pressure capillary irrigation infiltration simulation test in sandy soil water,the results showed that infiltration rate and the infiltration of time showed the power function relationship,and the accumulated volume of infiltration and infiltration time was a function of the number.Moist body similar to ellipsoid,and the spread of the level of infiltration radius is greater than the vertical depth,ellipsoid level of proliferation in the long axis direction was symmetrical,in the short axis vertical infiltration direction,from top to bottom asymmetry,and short on the next chief.
