农田暗管排水技术是土地排水、防止灌溉土地盐 碱化和改造中低产田的有效措施。与明沟排水相比具 有排水效果好,有效控制地下水位,节省土地,减少维 护费用等特点。 随着暗管铺设方法和排水材料的改进,该技术已 经取得了显著进展。由于挖沟铺管机械的发展,波纹 塑料排水管已得到广泛应用。我国自20世纪80年代 初研制应用波纹塑料排水管以来,应用面积逐渐扩 大。 Farmland tube drainage technology is an effective measure for drainage of land, prevention of salinization of irrigated land and transformation of middle and low yield fields. Compared with the ditches drainage has good drainage effect, effective control of groundwater level, save land, reduce maintenance costs and so on. With the concealed pipe laying method and the improvement of drainage materials, the technology has made significant progress. Due to the development of trenching pipe laying machinery, corrugated plastic drainage pipes have been widely used. Since our country developed and applied corrugated plastic drain pipe in the early 1980s, the area of ​​application has been gradually expanded.
