交口抽渭灌溉工程投入运行以来,为灌区农业的稳产和经济发展发挥了巨大的作用,粮食亩产最高达664公斤,是开灌前86公斤的7.7倍多,棉花亩产最高达67公斤,比开灌前增加55公斤。据统计,开灌以来,累计增产粮食43.68亿公斤,棉花1.39亿公斤,加上其它经济作显产值累计增收24.4亿元(按国家收购价格计),相当干国家投入的15.5倍,社会效益也十分显著。由于交口抽渭灌区始建干60年代困难时期,当时属三门峡水库淹没区,整个工程按十年临时工程设计,二期扩大工程建于“十年动乱”时期,设计标准低,施工质量差,属于典型的“干打垒”和“三边工程”,一开始就存在着先天不足。同时在长期运用过程中一直实行低水价格政策,靠国家补贴赔本供水。因此,使工程改造、设备更新缺乏资金,已形成机组老化,设备陈旧,渠道破烂,工程效益明显下降;抽水机姐定额出力不足,灌溉面积减少,输水渠道不能达到设计能力,决口跑水经常发生,工程管理难以为继。为此,改革水费价格已是爽口灌区迫在眉睫的问题。否则灌区效益没有保证,将影响灌区农业经济的发展。
Since the project was put into operation, the irrigation and drainage of Wei River has played a tremendous role in stabilizing agriculture and economic development in the irrigated area. Grain yield per mu is up to 664 kilograms, 7.7 times as much as 86 kilos before open irrigation and up to 67 kilograms per mu for cotton. 55 kg more than before irrigation. According to statistics, a total of 4.368 billion kilograms of grain and 139 million kilograms of cotton have been added since the start of irrigation. In addition, the total output value of other economies has increased by 2.44 billion yuan (15% of the national purchase price) Very significant. Due to the difficult period of construction of the cross-over irrigation and weir irrigation area in the early 1960s, it was a submerged area of Sanmenxia Reservoir at that time. According to the ten-year temporary project design, the second phase of expansion project was built during the “ten-year turmoil” period with low design standards, poor construction quality, Belongs to the typical “dry base” and “three-side project”, there is inherent deficiencies from the very beginning. At the same time in the long-term use of the process has been implemented low water price policy, relying on state subsidies for loss of water supply. As a result, engineering reconstruction and equipment renewal lack of funds have resulted in the aging of units, outdated equipment and the dilapidation of channels, and the obvious decrease of engineering benefits. The output of pumping units is insufficient, the irrigated area is reduced, and the water supply channels can not reach the designed capacity. , Project management unsustainable. To this end, the reform of water price is refreshing irrigation area imminent problem. Otherwise, there is no guarantee of efficiency of irrigated areas, which will affect the development of irrigated agricultural economy.
