全国300个节水重点县节水灌溉技术推广应用

Extension of water-saving irrigation technologies in 300 national key water-saving counties

"九·五"期间,全国300个节水重点县建设取得了显著的经济、社会、环境效益,并有力地推动了节水技术的全面推广应用。本文总结了推广应用的12项节水灌溉技术及应用实绩,包括水土资源优化配置技术、多水源优化和联合调度技术、渠道及管道高效输配水技术、高效喷灌及微灌技术、集雨节灌技术、管理技术及农艺技术等。

Significant economic, social and ecological benefits were obtained by means of constructions of 300 national key water-saving countries during the period of the Ninth Five-Year Plan. The constructions promoted a nation-wide extension of water-saving technologies. This paper summarized 12 water-saving technologies used in the construction, including optimal deployment of water and land sources, optimal and unified uses of various water sources, efficient water conveying technology through pipes and canals, sprinkler and micro-irrigation technology, rainwater harvest technology, management technology and agronomic technology, etc.
