摘要
在加入含钾矿粉、土壤,缺钾营养液培养条件下,硅酸盐细菌SB121和SB138从矿粉和土壤中活化的钾分别比对照增加2.7%～40.5%和1.6%～21.6%。两种硅酸盐细菌活化的钾素全部来自矿物结构钾。
The availability of K in three silicate minerals and a soil is promoted by silicate bacteria SB121 from 2.7%～40.5%, and SB138 is 1.6%～21.6%. Further research indicates that all the K released by silicate bacteria are from mineral K.
