摘要:

通过对世界钾盐资源储量及生产利用特征分析,指出中国钾盐行业亟待解决的问题以及杂卤石的应用前景。研究发现世界钾盐储量的56.98%高度集中于加拿大、俄罗斯和白俄罗斯,中国钾矿总储量丰富,但是可利用的钾不足20%,需要长期依靠进口满足内需;中国钾盐行业发展中存在可利用钾量少、国外找钾项目多处于建设阶段、钾肥生产能耗大、钾盐种类受限等问题。近年随着钾矿资源的消耗、传统化肥价格的攀升、硫肥需求量的增加,杂卤石作为一种成本低廉的缓释性多元素钾肥受到人们的关注,中国对优质杂卤石的需求量也将大幅度增加。因此,有必要进一步了解杂卤石的结构特点,加大杂卤石在农业上的应用分析并指出现有研究的不足,以实现杂卤石在中国的推广应用,缓解中国钾肥短缺的压力,实现农业的绿色发展。

Abstract:

Based on the analysis of the world′s potash reserves and production and utilization characteristics,some urgent problems in the development of China′s potash industry and application prospect of polyhalide were pointed out.It was found that 56.98% of the world′s potash reserves were highly concentrated in Canada,Russia and Belarus.China′s total potash reserves were rich,but less than 20% of the available potash deposits were available,which required long?term dependence on imported potash fertilizer to meet domestic demand.There were some problems in the development of China′s potash industry,such as the small amount of available potassium,most foreign potassium exploration projects in the construction stage,high energy consumption of potash fertilizer production,and limited types of potash salts.In recent years,with the increase of potassium resource consumption and traditional chemical fertilizer price,and the demand for sulfur fertilizer,as a low?cost slow?release multi?element potassium fertilizer,polyhalite had attracted people′s attention,and China′s demand for high?quality polyhalite would also increase significantly.Therefore,it is imperative to further understand the structural characteristics of polyhalite,analyze the application of polyhalite in agriculture and point out the shortcomings of the existing research,so as to realize the promotion and application of polyhalite in China to alleviate the pressure of potash fertilizer shortage and the green development of agriculture.

Key words: potassium salt, reserves, resource situation, polyhalite, development and application
