摘　　要：研究了硅酸盐细菌在实验室及盆栽条件下的解钾活性,并在扫描电镜下观察了硅酸盐细菌对钾长石结构的改变。结果表明:硅酸盐细菌对含钾矿物确有溶解作用,能使固定钾转化为可溶性钾,对植物的生长及产量提高有明显促进作用。The potassium-dissolving ability of silicate bacteria was studied through experimental method and pot planting, and the change of the structure of powered rock potassium was observed by the SEM. The results showed that the silicate bacteria can change the structure of the rock, release K and increase the yield of some crops.
