风能是一种永不枯竭、无污染的巨大的能源。合理地利用风能对节约常规能源具有深远的意义。利用风能提水灌溉农田,在我国已有悠久的历史。目前常规能源越来越紧张,利用风能提水灌溉农田就更有必要,因此进行经济效益的预测十分重要。风能在农田灌溉中经济效益的预测内容包括;风能资源的计算、节油量和灌溉能力。
Wind energy is a huge source of energy that is never depleted and pollution-free. The rational use of wind energy has far-reaching significance for saving conventional energy. The use of wind to raise water to irrigate farmland in our country has a long history. At present, conventional energy is getting more and more tense. It is even more necessary to use wind energy to raise water to irrigate farmland. Therefore, it is very important to forecast the economic benefits. Wind energy in farmland irrigation in the forecast of economic benefits include; calculation of wind energy resources, fuel-efficient and irrigation capacity.
