【摘要】 我国钾肥需求量逐年增加,80％需要进口,但同时又有大量的低品位非水溶性钾矿资源没有利用,利用非水溶性钾矿生产长效钾肥既能缓解钾肥短缺的矛盾,又可以解决普通钾肥对环境的污染和破坏。长效钾肥原料分布广,生产和施用技术简单,成本低,易于推广普及形成产业化,其对农业可持续发展将会产生重要的促进作用。更多还原

【Abstract】 In China, more and more the potash fertilizer is needed yearly, 80% of which are imported from overseas, and at the same time, a large amount of the potash mineral resources with the low-grade and not dissolving in water are not used. We can produce the potash fertilizer with the long-term effectiveness from the potash mineral not dissolving in water, in order to solve the problem of the potash fertilizer shortage and prevent its pollution and damage to the environment. The raw materials of the potash fertilizer with the long-term effectiveness are distributed broadly, the technique of its production and application is simple with the low production cost, therefore, it is easy to be popularized and realize its industrialization to promote the agricultural sustainable development.更多还原
