摘要
根据前人直接应用含钾岩石的成功经验；土壤中供钾矿物和含钾岩石中含钾矿物的相似性；土壤中含钾矿物的有效性和含钾岩石供钾潜力的研究结果，本文论述了组成矿物主要为云母类矿物（黑云母、白云母、海绿石、伊利石）的含钾岩石，农业直接应用可能具有良好效果。并根据笔者对贵州各类以白云母、伊利石（水云母）为主要矿物的水云母粘土岩、页岩、粉砂岩和火山凝灰岩（绿豆岩）的供钾潜力和释钾能力的研究结果，发现彼此供钾潜力相差悬殊，指出对含钾岩石进行农业地质开发研究，寻找勘探出供钾潜力大的含钾岩石，直接应用于农业，将对大农业的发展具有重要意义。
Based on successful experiences of our predecessors using directlyK-bearing rocks, similarity of K-supply minerals in soil to K-bearing mineral inK-bearing rocks, and studied results on efficience of K-bearing minerals of soiland K-supply potentiality of K-bearing rocks, the paper will expound possibleeffect of directly applied K-bearing rocks, composed mainly of mica minerals(biotite, muscovite, glauconite and illite), to agriculture. According to my studyon K-supply potentiality and K-release ability of hydromica claystone, shale,siltstone and tuff (so-called 'green gram rock' of Guizhou, i. e. clayizational vitrictuff) in Guizhou, which also consist mainly of muscovite and illite (hydromica),it is found out that these rocks are quite different in their K-supply potentiality.It is pointed out that studing furtherly K-bearing rocks and seaching for abundantK-supply rocks to be apllied to agriculture are very important for developingagriculture.
