摘要
根据试验资料,建立春玉米耗水量的数学模式,计算不同生育阶段的耗水量。在此基础上,借助农田水分平衡方程,设计出计算春玉米不同生育阶段灌溉量的动态变化方程,综合考虑未来天气趋势和土壤性质的作用,判断未来旱象的发生发展,科学地决策抗旱措施。
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.
