| 摘要: |
| 盆栽试验结果表明，玉米、油菜和黑麦草等植物能够直接利用片麻岩中的矿物结构钾。不同种类的植物对矿物结构钾的利用能力有显著差异，而且矿物粒径的变化对钾的植物有效性影响很大。 |

| Comparison of Structural K Mobilization and Utilization Among Plant Species |

| Abstract: |
| Structural K in gneiss could be mobilized and utilized by maize (Zea mays L.ND60), pak-choi (Brassica campestris L. ssp. chinensis (L.) Mokina. var. cammunis Tsen et Lee, cv Wuyueman chnensis L.) and ryegrass (Lolium multiflorum Lam. ). Among the plant species tested, more profound release of structural K was observed with maize and ryegrass. Besides, the mobilization of structural K negetively correlated with the particle sizes of gneiss. |
