摘要
中国的土壤存在既富含钾又缺钾的现象,钾肥大量依赖于进口。硅酸盐细菌能分解土壤中的云母、长石等硅酸盐矿物,释放出钾、磷等元素,将难溶性钾转化为可被植物直接利用的可溶性钾,促进植物吸收和生长,此外,还能促进植物根部有益微生物繁殖,增强作物抗病能力。文中从硅酸盐细菌解钾效果及最适条件研究、解钾作用机理研究和问题与展望三个方面进行综述,提出进一步研究和应用的方向。
Potassium fertilizer relies on import in China which has＂rich＂and＂poor＂potassium soil. Silicate bacteria can release potassium and phosphorus to the plants by decomposing Mica,feldspar and other silicate minerals in the soil,so plants can grow better by absorbing potassium,more useful bacteria and higher disease resistance. This paper reviews the potassium releasing effect by silicate bacteria and the optimal culturing conditions of the silicate bacteria,the potassium releasing mechanisms and the silicate bacteria application prospect to direct the future studying.
