【摘要】 文中对非充分灌溉条件下作物优化灌溉制度如何制定进行了研究。其特点是将作物产量模型、耗水规律模型和土壤水分变化动态模型相结合,以产量最高为目标函数,建立了计算机优化决策系统。该研究成果可使有限的水量在作物生育期内发挥最大的效率,对优化配置水资源,实现农业高效用水具有重要作用。实例研究结果说明,所建模型及求解方法是合理与可行的。更多还原

【Abstract】 In the paper ,the optimal irrigation schedule of crop under the condition of insufficient irrigation is studied.The characteristics of it are that it combines crop yield model,consumptive water regularity model and soil moisture regime model.The objective function of this model is to obtain the maximum yield by establishing the computer optimal decision system.This research result can make the limited water volume be used efficiently in the whole period of crop growing,and has important effects on the aspects of optimal allocation and effective use of water resources.An example of research indicates that the model and the solution methods are rational and feasible.更多还原
