摘　　要：简要介绍了我国和世界钾盐资源的分布及钾的供需状况,以及缓解我国缺钾局面的主要途径;着重论述了钾长石制钾肥的研究进展;最后阐述了钾长石提钾中存在的问题及发展前景。The distribution of the potash salt resources is unbalanced in the world. It is very poor in China, but the potash feldspar ores are considerably rich. Extracting potash from those ores is an effectual way to solve the problem of potash fertilizer shortage. The develop-ments in extracting potash from potash feldspar are reviewed in this paper.and the technical difficulties and industrial prospects are discussed briefly.
