Study on Intelligent Irrigation System of Winter Wheat Based on Fuzzy Decision Theory

In order to irrigate crops at the right time and appropriate amount,an intelligent irrigation system considering soil-plantatmosphere continuum(SPAC) was studied in this article.First of all,the most appropriate soil moisture is set at different stage of wheat growth.Then,the evapotranspiration of wheat crop is predicted by meteorological parameters.Finally,the irrigation water is decided by using fuzzy decision theory considering the effects of soil moisture,crop evapotranspiration and growing stage.Result shows that fuzzy intelligent decision for irrigation considering multi-factors is much more reasonable than those considering only one factor.
