摘要
本文对贵州有关含钾岩石（水云母粘土岩、页岩、粉砂岩和火山凝灰岩（绿豆岩））进行了释钾作用和供钾潜力的研究，结果表明，不同含钾岩石的释钾能力和供钾潜力有显著差别，讨论了影响含钾岩石供钾潜力的因素。据此，并根据土壤学的研究成果，指出寻找、勘查、研究开发供钾潜力高的含钾岩石直接应用于农业的重要意义。
K-release and K-supplying potential of K-rich rocks (hydromica clay rock, shale and silty rocks and volcanic tuff) in Guizhou province are studied in the paper. The results show that difference of Krelease and K-supplying potential in different K-contained rocks is very outstanding. Factors of influence on K-supplying potential are discussed. On the basis of those and research results of soil scince, significance of expolation, research and direct application of rocks of high supplying potential to agriculture is indicated.
