暗管排水是一项正在蓬勃发展的先进的排水技术。1985年以来在新疆生产建设兵团农二师29团农场已埋设暗管13000余亩,并开展了暗管排水改良盐碱地试验,经3～5年的观测已取得了初步成果。1987年经农牧渔业部批准立项,与荷兰欧洲咨询公司签订了由荷兰王国提供854万荷兰盾长期低息贷款,引进全套暗管排水机械设备和PVC原料,建设15万亩暗管排水工程的合同。1989年在荷兰专家指导下进行了全农场16.5万亩土地的暗管排水规划设计。采取了埋设田间管、集水管两级暗管,在集水管末端设小泵站提水入现有明沟(支、斗排)的规划方案。田间管采用内径7cm、9cm和11.5cm的波纹塑料管,外填7cm厚砂石滤料
Vascular drainage is a booming advanced drainage technology. Since 1985, 29 farms of Nongfu division of Xinjiang Production and Construction Corps have buried more than 13,000 mu of underground pipes and carried out experiments on the improvement of saline drainage by concealed pipe drainage. Preliminary observations have been made after 3 to 5 years of observation. In 1987, the Ministry of Agriculture, Animal Husbandry and Fisheries approved the project, and the Netherlands signed a consulting firm in the Netherlands to provide 8.54 million long-term low-interest loans Guodian, the introduction of a full set of aqueduct drainage machinery and equipment and PVC raw materials, construction of 150,000 mu of underground pipe drainage project contract. In 1989 under the guidance of Dutch experts under the guidance of the entire farm 165000 acres of underground pipe drainage planning and design. Take the planted field pipe, two sets of underground pipe, set at the end of the water collection station to pump into the existing open ditch (branch, bucket row) planning program. Field pipe with corrugated plastic pipe with inner diameter of 7cm, 9cm and 11.5cm, filled with sandstone filter 7cm thick
