节水灌溉技术是比传统的灌溉技术明显节约用水和高效用水的灌水方法,措施和制度等的总称。是否节约灌溉用水,用水是否高效是以单位作物产量总耗水量(从水源算起直到田间)多少来衡量。因为节水与否和高效与否,都是相对的概念,所以节水灌溉技术也是不断发展,其效率也是不断提高的。主要针对我国现行的一些节水灌溉技术进行了研究探讨。 Water-saving irrigation technology is a general term for irrigation methods, measures and systems that obviously save water and water more efficiently than traditional irrigation techniques. Whether irrigation water is saved or not, the efficiency of water use is measured by the total amount of water consumed per unit of crop (from the water source to the field). Because water conservation is not efficient or not, are relative concepts, so water-saving irrigation technology is also continuous development, its efficiency is also rising. This paper mainly studies some current water-saving irrigation technologies in our country.
