我国钾资源贫乏，目前使用的钾肥主要靠国外进口．通过物理、化学和生物的方法，对云母类矿石进行活化而制成云母类矿物钾肥，不失为解决我国南方土壤钾素缺乏问题的一条有效途径．本文对中科院地化所提供的通过活化处理制取的云母类矿物钾肥进行了肥效试验．结果表明，施用云母类矿物钾肥与施用等钾量的氯化钾相比，无论是作物的吸钾能力，还是土壤的供钾能力．前者都比后者显著提高．因此，开发云母类矿物钾肥资源具有广阔的前景．
China’s poor potassium resources, the current use of potash mainly by foreign imports. It is an effective way to solve the problem of potassium deficiency in the southern soil of our country through physical, chemical and biological methods to activate the micaceous ore to make mica mineral potassium fertilizer. In this paper, the fertilization effect test of mica mineral potash prepared by activation treatment provided by the Institute of Geochemistry, Chinese Academy of Sciences was conducted. The results showed that the application of mica mineral potassium fertilizer potassium and potassium than the application of potassium compared to both potassium absorption capacity of crops or soil potassium supply capacity. The former is significantly higher than the latter. Therefore, the development of mineral resources of mineral mica has broad prospects.
