近年来,衡水地区利用集资方式进行田间防渗工程建设,经济效益显著。据统计,仅1984年一年,冀、枣、衡,武四县就建成防渗渠道22.75万米,扩大灌溉面积1.5万亩。衡水地区,长期以来沿用传统的上垄沟进行田间灌溉,因沟水渗漏严重,致使能源大量浪费,浇地成本高,经济效益低。 In recent years, Hengshui region using fund-raising methods for field seepage control construction, significant economic benefits. According to statistics, in 1984 alone, Hebei, Zao, Heng and Wusi counties built 227,500 meters of seepage prevention channels and expanded irrigated area of ​​15,000 mu. Hengshui has long been using traditional furrow irrigation for field irrigation. Due to the serious seepage of ditch water, a lot of energy wasted, the cost of irrigating land was high, and the economic benefits were low.
