以含钾矿粉和土壤为材料，用硅酸盐细菌进行解钾试验。结果表明，硅酸盐细菌对不同类型矿粉的解钾能力不同：炭渣＞石骨子＞绿豆岩＞正长石。解钾量与矿粉粒径密切相关，随矿粉粉径的减小而增加：ｙ＝９．６７５ｘ－０．７２１，ｒ＝－０．９９２＊＊。硅酸盐细菌接到土壤后长期培养，可增加土壤中的速效钾，但其增加量不稳定。土壤的营养条件对硅酸盐细菌的解钾效果有一定影响。
To potassium-containing ore and soil as materials, with silicate bacteria for potassium test. The results showed that silicate bacteria had different ability to dissolve potassium for different types of mineral powders: cinder> rock bones> mungbean rock> orthoclase. The amount of potassium release is closely related to the particle size of the ore and increases with the decrease of the diameter of the ore powder: y = 9.675x-0.721, r = -0.992 **. Long-term culture of silicate bacteria after they have been soaked in soil increases the available potassium in the soil, but the increase is unstable. Soil nutrient conditions have some impact on the potassium-releasing effect of silicate bacteria.
