关于宁夏枸杞实行节水灌溉的思考

On Water-saving Irrigation to Lycium Barbarum L.in Ningxia

针对宁夏引黄灌区黄河引水量逐年降低和宁夏枸杞在宁夏经济发展中的重要地位,结合宁夏枸杞抗旱抗盐生理基础和当前先进的作物节水灌溉原理和方法,提出开展控制性交替灌溉节水栽培技术的必要性和可行性,对于改变当前宁夏引黄灌区水资源紧张、农业灌溉水分利用效率低的现状以及加速宁夏枸杞的进一步发展具有重要的现实意义。

The situations of gradually decreasing of irrigation water volume from yellow river per year in Ningxia irrigation area and the important position of Lycium bararum L. in economy development of Ningxia were analyzed, According to the salt tolerance and drought resistance of Lycium bararum L. and the advanced theories and methods of water-saving irrigation on some crops, the necessity and feasibility of applying controlled alternative irrigation technology on Lycium bararum L, were put forward. It had realistic meaning to solve the situation of shortage of water resource, the lower agricultural irrigation water efficiency in Ningxia irrigation area and to deeply develop Lycium bararum L. in the future,
