农田排水系统怎样适应农业现代化的需要?在重盐碱地区采用什么方式排水效果好?近几年,新疆生产建设兵团在农二师二十九团进行的暗管排水试验,取得了可喜的成果。农田暗管排水是我国80年代由欧洲引进的一项农田排水新技术,它以埋设在地下的管道代替明沟排水渠,地下水通过管道周围的滤料和管壁渗入管内,再由暗管流入排水支渠,达到排除盐碱,降低地下水位的目的。农牧渔业部把暗管排水列为“七五”计划期间的一项重点科研项目,由新疆生产建设兵团
In recent years, Xinjiang Production and Construction Corps in the Nongersi Tung 29 groups of underground pipe drainage test, and achieved gratifying results. Farmland tube drainage is a new technology of farmland drainage imported from Europe in the 1980s. It replaces the ditches and drainage channels with buried pipelines. The groundwater infiltrates into the pipe through the filter media and pipe wall around the pipe, and then flows into the drainage pipe Branch canal, to exclude salt, reduce the purpose of groundwater level. Ministry of Agriculture, Animal Husbandry and Fisheries classified duct drainage as a key scientific research project during the Seventh Five-Year Plan. The Xinjiang Production and Construction Corps
