Analysis on the present situation and problems of potash feldspar soil conditioner in China

以钾长石为代表的非水溶性钾矿资源开发,对于补充我国钾肥供需缺口,降低对外依存度,保障农业用肥安全具有重要意义。近些年来,随着我国耕地质量问题日益凸显,以钾长石为主要原料生产制备矿物源土壤调理剂,逐渐探索出一种较好的资源开发利用模式。本文总结了目前我国市场上登记有效的钾长石土壤调理剂产品发展现状,梳理分析了该类产品的主要原料、生产工艺、技术指标及其农用效果,探讨了与行业发展相关的政策支持、产品和技术创新、标准体系建设等问题,并提出了有关建议。

The development of insoluble potash feldspar mineral resources,represented by potash feldspar,is of great significance to supplement the gap between supply and demand of potash fertilizer in China,and it can reduce the dependence on foreign countries and ensure safety fertilizer amount in agriculture. In recent years,with the increasing question on quality of cultivated land in China,the preparation of mineral soil conditioner by potash feldspar has gradually formed a better resource development and utilization pattern. This paper summarized the current status of the development of potash feldspar soil conditioner products registered in China＇s market and the main raw materials,production technology,technical indexes and agricultural effects of these products,and discussed the policy support related to the development of the industry,product and technological innovation,standard system construction and other issues,put forwarded the relevant suggestions.
