| 摘 要： | 本文对土壤钾的形态、矿物钾释放的影响因素及钾的固定、土壤含钾矿物与土壤供钾能力间关系、矿物钾的植物有效性进行了综述 ,表明土壤钾素从有效性的角度进行划分时 ,不能仅把速效性钾和1mol/L热硝酸提取的缓效性钾列为作物吸钾的主要来源 ,而忽视矿物钾的作用 .

| Abstract: | Forms of soil potassium, factors of mineral K-release, fixation of soil potassium, relationship between K-containing minerals and K supplying potential of soils and availability of mineral K for plants were summarized. Results showed that available potassium and slowly available potassium are important for potassium nutrition of plant but we should also pay attention to mineral-K. |
