Determining of Irrigation Amount of Spring Corn and Drought-resistant Strategy

The mathematical model of water consumption of spring corn was grven (?)sumption in each developmental stage was calculated.Forthermore,the dynamic model,estimatingirrigating amount of spring corn in different stages,was designed based on water balance equationof farmland so as to judge the developing trend of drought in the future through synthetical con-sideration of weather trend and soil character.Finally,the drought-resistent strategy was made.
