地处南阳盆地的鸭河口灌区,自2970年开灌以来,仅灌溉因素增产粮食248万 t,棉花495万担,增加农业产值47亿元。以占南阳市1/6的耕地,生产了全市1/4的粮食和1/2的棉花,对南阳经济社会的发展产生了巨大促进作用。但足,从目前来看,灌区的潜力并未充分发挥。一是水资源开发利用不够。鸭河口灌区设计灌溉面积15.87万 hm~2,现有有效灌溉面积8.84万 hm~2。近几年,国家把鸭河口灌区列为节水改造重点灌区,进行持续投资建设,产生了巨大的节水效
Located in the Yalu River Irrigation District of Nanyang Basin, since the irrigation was started in 2970, only the irrigation factor has increased the output of 2.48 million tons of grain and 4.95 million tons of cotton, increasing the agricultural output value by 4.7 billion yuan. Accounting for 1/6 of the cultivated land in Nanyang City, producing 1/4 of the city’s grain and 1/2 cotton, which has greatly promoted the economic and social development of Nanyang. But enough, from the current point of view, the potential of irrigated areas has not been brought into full play. First, water resources development and utilization is not enough. Irrigation area of Yakoukou Irrigation Area is 158,700 hm ~ 2, and the existing effective irrigation area is 88,400 hm ~ 2. In recent years, the state has listed Yahekou Irrigation District as a key irrigation area for water-saving reform and has continued to invest in it, resulting in a huge water-saving effect
