通过资料对比分析和试验研究，对宁夏引黄灌区植林的可行性分析结果表明，宁夏引黄灌区属于植棉临界区，与新疆北疆、甘肃河西走廊及内蒙河套灌区同属我国西北内陆棉区的特早熟干旱棉花次适宜区；宁夏引黄灌区光能资源、灌溉、土壤等农业生产条件对植棉十分有利，但热量资源略显不足，是该地区植林的限制因素。目前宁夏引黄灌区的植棉技术研究已取得突破性进展，在一定范围内植林条件已基本成熟。
Through the comparative analysis of data and experimental study, the feasibility analysis of afforestation in Yellow River Irrigation Area in Ningxia showed that the Yellow River Irrigation Area in Ningxia belonged to the critical area for cotton planting, and both Xinjiang and Xinjiang Inner Mongolia Hexi Corridor and Inner Mongolia Hetao Irrigation Area belonged to the inland cotton area of Northwest China. Of the premature arid cotton sub-suitable area; Ningxia Yellow River irrigation area of light energy resources, irrigation, soil and other agricultural conditions are very beneficial to cotton, but slightly less than the thermal resources, is the limiting factor for planting in the area. At present, the cotton planting technology in the irrigation area of Yellow River diversion in Ningxia has made breakthrough progress, and the planting conditions have been basically mature within a certain range.
