摘　　要：钾是保证农作物生长的必须营养元素,钾盐资源主要用于钾肥生产。作为钾肥消费大国,中国钾资源匮乏,钾盐已经被列入战略性矿产目录,钾盐资源供应安全对国家安全保障具有重要意义。列举了全球和国内钾盐资源的基本情况,分析了全球和国内钾肥的生产和消费情况,介绍了中国钾盐资源制备钾肥的主要生产技术,并结合中国钾盐生产现状,对未来中国钾盐行业提出了一些建议,包括持续加快接续资源选区评价、持续关注盐湖卤水品位变化、加强工艺技术研究等。Potassium is an essential nutrient for crop growth.Potassium salt resources are mainly used for potassium fertilizer production.As a major consumer of potassium fertilizer,China is short of potassium resources.Potassium salt has been listed in the strategic mineral catalog,and the supply security of potassium salt resources is of great significance to the national security.The basic situation of global and domestic potassium resources were listed,the production and consumption situation of global and domestic potassium resources were analyzed,and the main production technology for preparing potash fertilizer from Chinese potash salt resources were introduced.Moreover,combined with the current situation of potassium salt production in China,some suggestions for the future potash salt industry in China were put forward,which included evaluation of the selected areas of continuous resources,continuous attention to the change of brine grade in salt lakes,and strengthening the research on technology.
