中牟县总土地面积1416.7km~2,引黄灌溉设计面积3.6万hm~2,水稻种植面积0.57万hm~2。县域内历史上多次受黄河频繁改道冲击的影响,在境内形成了沙丘、洼地、沙地、涝地并存的地貌。从60年代初开始,中牟县就发展引黄灌溉,淤改土地,相继建成了杨桥、三刘砦两个大、中型引黄灌区。经过30多年引黄水利建设,建成了比较完整的引黄灌溉体系,引黄灌溉控制了全县60%的耕地。但是由于渠系建筑物年久失修,有的已失去了对渠道运用的调控能力,加上灌水技术粗放,灌溉模式陈旧,造成灌区水资源浪费严
Zhongmu County has a total land area of 1416.7km ~ 2, designed irrigation area of 36,000 hm ~ 2 and irrigation area of 0.57 million hm ~ 2. In the history of the county, the impact of frequent diversions and diversions in the Yellow River has repeatedly led to the formation of coexistence of dunes, depressions, sandy land and flood-prone land in the territory. Since the early 1960s, Zhongmu County has been developing irrigated land and silting land for reforming the Yellow River. Two large and medium-sized irrigated areas have been built successively, namely Yangqiao and Three Liuzhai. After more than 30 years of construction of the Yellow River water conservancy project, a relatively complete system for dredging the Yellow River has been built and irrigated by the Yellow River has controlled 60% of the cultivated land in the county. However, due to the dilapidated buildings of the canal system, some of them have lost their ability to regulate and control the use of the channels. In addition, the extensive irrigation technology and outdated irrigation modes have caused the waste of water resources in irrigation districts
