Abstract
To study the law of irrigation water infiltration in soil is the basis of putting forward reasonable irrigation system. This paper takes YaoBa Oasis in Alxa Zuoqi,Inner Mongolia, China as the research object, based on field investigations and data collection, and chooses three test sites at the field to obtain the parameters of the model. The change of soil water content in different depth was simulated by Hydrus-1D model in 30 days after irrigation. The results shows that under the local existing irrigation system, the groundwater recharge is limited, and loam is an ideal agricultural soil. The results of the simulation are in good agreement with the experimental results, so the research results can provide scientific basis for the development of a more reasonable irrigation scheme in YaoBa Oasis.
