摘　　要：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 comparison of the data and test the feasibility of growing cotton(Gossypium hirsutum L. )in the irrigated area of Ningdxia was studied.Results showed that the Ningxia irrigated area shouldbelong to critical zone of growing cotton and this area,as well as northern irrigated area of Xinjiang,Hexi irrigated area of Gansu ,Hetao irrigated area of Inner Mongolia,should belong to extremely ear-ly ripening subsuitable zone of growing cotton in northwestern of China, Although production condi-tions(e,g.sun radiation,convenient irrigation and good agricultural soil types etc.)were profitablefor cotton growing, the shorter growing period and lower cumulative temperature during growing peri-od of cotton were critical factors of growing cotton. Recently,a key technological breakthrough ofgrowing cotton has been made in this region. Growing cotton in this region will obtain great profit andthe cotton production will have a great development.
