中卫市南山台扬水灌区应对缺水调整作物种植结构的措施与成效

摘要

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.
