我省几年来兴建了几座灌排結合的抽水站,使用一套动力机水泵,輔以一定的控制建筑物,使它能发揮灌溉、排涝兩种作用。它的好处主要是:提高机械利用率,减少动力設备裝置,扩大受益面积,节省工程投資,减少經常管理养护費用。通过实踐証明,今后 In recent years, our province has built several pumping stations that combine irrigation and drainage with a power pump, supplemented by a certain number of control buildings to make it play two roles of irrigation and drainage. Its main advantages are: to improve the utilization of machinery, reduce power plant equipment, expand the benefit area, save engineering investment, reduce the cost of regular management and maintenance. Through practice, in the future
