1项目区现状扶沟县规模化节水灌溉增效示范项目项目区主要农作物为小麦、玉米、大豆等,经济作物主要为瓜、蔬菜、棉花,灌溉主要采用井灌,灌溉规模较小。随着工农业发展,地下水需求量加大,地下水得不到有效补给,超采现象相当严重,致使地下水位连年下降。但是,农民水危机意识不强,作物灌溉为大水漫灌,水资源浪费严重,形成恶性循环,机井报废率高,提水设备更新频繁,灌溉成本增加农民负担加重,严重影响当地粮食增产、农民增收。2节水灌溉增效示范项目建设的必要性
1 Status of the Project Area Large-scale Water-saving Irrigation and Efficiency-enhancing Demonstration Project in Fugou County The main crops in the project area are wheat, corn and soybean. The main cash crops are melons, vegetables and cotton. The main irrigation is small-scale irrigation. With the development of industry and agriculture, the demand of groundwater is increased, groundwater can not be effectively replenished, and the phenomenon of over-mining is rather serious. As a result, the groundwater table has been declining year after year. However, the awareness of peasants in water crisis is not strong, irrigation of crops is flood irrigation, serious waste of water resources leads to a vicious cycle, high reject rate of wells, frequent updating of water supply equipment, increased irrigation costs and increased peasants’ burden, seriously affecting the increase of local grain output. Peasants Income. 2 water-saving irrigation efficiency demonstration project construction necessity
