The measurement and effect of crop growing adjustment according water supply shortage in Nanshantai irrigation area of Zhongwei city

中卫市南山台扬水灌区位于宁夏中部干旱带,现有灌溉面积1.31万hm2,灌区曾经以粮食作物为主,灌溉需水量大,导致灌区严重缺水;调整作物种植结构后,大面积种植果树,推行节水灌溉,灌区缺水的局面逐步扭转.

Nanshantai pumping irrigation area in ZhongweiCity lies in the middle arid area of Ningxia with 13,067 hm2 of irrigation area, which once lived on grain crop. Then a lot of water was needed, causing great water shortage in irrigation area. After adjusting crop planting structure, a large area of fruit trees have been planted and water-saving irrigation has been pushed forward. In this way, the situation of water shortage in irrigation area has been gradually improved.
