灌区调度的目的在于将适时、适量的水分分配给各种作物,使有限的水资源能产生最大的经济效益。当水量不足时,可以采用非充分灌溉,使水资源发挥最大效益。灌溉水量影响因素较多,应该与水价、降雨量预测相结合,适当分配水量。 The purpose of irrigation scheduling is to allocate timely and proper amount of water to various crops so that the limited water resources can produce the most economic benefits. When the amount of water is insufficient, insufficient irrigation can be used to maximize the benefits of water resources. Irrigation water more influencing factors, should be combined with the price of water, rainfall forecast, the appropriate allocation of water.
