| Abstract: | The article describes the progress of study on soil water in one hundred years and the development at present.The use of soil water potential provides a standard for the study of water movement in SPAC.Based on the theory of energy equilibrium and water mass balance.The prediction of water mass balance,the prediction of water demand and irrigation schedule are made.A treat system that made up of monolithic-computer and tention meter will be helpful to realize the automatic control on field irrigation. |
