机井节能改造与管道输水灌溉是一种综合性节水节能的新型灌溉技术,具有节水、节能、节地、省工、提高灌溉效率和灌水质量,便于机耕和交通等特点。国内虽早在五十年代就有应用,但由于多种技术问题没能解决,加之井灌较少,因此,发展较慢。近 The well energy saving and pipeline water diversion irrigation is a new type of integrated water saving and energy saving irrigation technology. It has the characteristics of saving water, saving energy, saving land, saving labor, improving irrigation efficiency and irrigation quality, and facilitating tillage and traffic. Although the country as early as the fifties there are applications, but due to a variety of technical problems can not be solved, coupled with less well irrigation, therefore, the development is slow. near
