| Abstract: | Based on the theories of soil water dynamics, field trials and theoretical analyses had been carried through in this paper and the mathematical model was founded. According to the experiment result and other reference data, the parameters of soil water movement were established. The mathematical models were solved by finite difference method. The results of the trials showed that the data of numerical simulation of the models was in good agreement with the data of trials in the rice-field. The models were reliable and had practical values. |
