地处渭北黄土高原的富平县,是陕西省的主产粮县之一。这里水利资源贫乏,90％是地下水。为了抗旱保收,解放以来全县打灌溉机井5,300多眼,配套机井4,800多眼。但由于井深水小,效益较差。往往夏灌用水季节供电不足,使灌溉无法进行。为了提高井灌效益,1976年起在井边修建蓄水池,采取闲蓄忙用、小蓄大用、开源节流、调节用水的办法,保证了全县36.6万亩耕地井灌,同时利用井边池发展了养鱼生产。井边池养鱼有很多优点:(1)对水资源二次利用,一般不要增加劳力和投资,就能多一项生产和收益。(2)井边池面积多在半亩左右,水深3—4米,
Fuping County, located in Weibei Loess Plateau, is one of the main grain-producing counties in Shaanxi Province. Water resources here are poor, 90% of groundwater. In order to maintain the drought relief, the county since the liberation of irrigated wells more than 5,300 eye, supporting more than 4,800 well drilled eye. However, due to the small depth of water, the benefit is poor. Often the summer irrigation water supply season is not enough, so irrigation can not be carried out. In order to improve the benefit of well irrigation, a reservoir was constructed at the well side in 1976, taking busy storage, small storage and large-scale use, increasing revenue and reducing expenditure, and regulating water use to ensure that 366,000 mu of cultivated land and well were irrigated in the entire county while utilizing the wellbore development Fish production. Wellbore fish culture has many advantages: (1) The secondary use of water resources, generally do not increase labor and investment, we can produce more than one production and revenue. (2) Weitai pool area more than half an acre, water depth 3-4 meters,
