提出了一种利用作物对灌溉响应的数值模型和气象预报确定灌溉深度的方法。为了优化各灌水深度，引入了虚拟收益的概念，虚拟收益与灌水间隔内的蒸腾量增量成正比。在数值试验中使用了一个模拟水、溶质和热传输以及作物响应的数值模型。结果表明，最佳灌水深度可以小于获得最大产量的灌水深度。
A method of determination of irrigation depth using a numerical model of crop response to irrigation and weather forecast was presented. To optimize each irrigation depth, a concept of virtual income, which is proportional to an increment in transpiration amount during an irrigation interval, is introduced. A numerical model that simulates water, solute, and heat transport and crop response is used in a numerical experiment. Results indicated that the optimized irrigation depth can be smaller than the value which attains maximum yield.
