鸭河口灌区既是河南省最大的自流灌区,也是南阳市农业发展的重要保障。但是由于灌区始建于1966年,处于非常年代,工程存在着较多的问题:一是基建任务遗留大;二是灌区多年来带病带残运行;三是建筑物老化失修;四是输水能力低;五是排水河道大多未予治理,洪涝面积较大等,一定程度上影响着工程效益的发挥,制约了灌区的发展。 The duck mouth estuary irrigation area is not only the largest gravity irrigation area in Henan Province, but also an important guarantee for agricultural development in Nanyang City. However, since the irrigation area was built in 1966 and was in its infancy, there are many problems in the project. One is the large legacy of infrastructure projects. The other is that the irrigated areas have been in operation for a long time. Thirdly, aging buildings are disrepair. Fourth, Low capacity; Fifth, most of the drainage channels have not been treated, floods larger, etc., to a certain extent, affect the performance of the project, has restricted the development of irrigated areas.
