[Objective]Research in the process of the drip irrigation infiltration laws of soil water infiltration has important significance for reasonable drip irrigation and crop yield increase.[Methods]This text used Fluent software to simulate the drip irrigation planting patterns of 50 cm space to calculate the soil water infiltration.[Results]It got the contours of velocity distribution and moisture distribution.Simulation results and actual test results were in agreement.Infiltration velocity decreased with the...
