摘　　要：针对我国钾肥资源短缺问题,分析了土壤钾资源的开发潜力,概述了土壤矿物钾的存在状态及其释放特点,综述了硅酸盐细菌、富钾植物和有机酸活化土壤矿物钾的能力与机理,并展望了活化土壤矿物钾的三种途径在生产中的应用前景。Focus on the problem of a deficiency of potassic fertilizer resources, the development potential of the soil potassium resource was analyzed, and forms and releasing features of the mineral potassium in soils were generally discussed. The mechanism and capability of mobilization of mineral potassium in soils by silicate bacteria, K-enriched plants, and organic acids were reviewed. The prospects for three ways of mobilization and utilization of mineral potassium in soils, applied in practice, were looked ahead.
