云母矿物中的钾是土壤钾素的主要来源。研究云母的释钾过程，不仅对阐明云母的风化机理，钾在土壤中迁移与富集，钾循环等过程有重要意义，而且还可以指导利用这类含钾资源。 云母中钾主要存在于其晶格中，部分可经风化或人工活化释放出来。土壤学中，把土壤或岩石经１ｍｏｌ／
Potassium in mica minerals is the main source of soil potassium. Studying the process of potassium release from mica is not only important for elucidating the weathering mechanism of mica, the process of potassium migration and enrichment in soil, and potassium recycling, but also can guide the utilization of such potassium-containing resources. Mica mainly exists in the lattice of mica, some can be released by weathering or artificial activation. Soil science, the soil or rock by 1mol /
