| 摘 要： | 以钾长石粉为惟一钾源的硅酸盐细茵选择性培养基筛选能够降解土壤中钾元素的细菌.利用梯度稀释分离法和平板划线分离法对其中的细菌进行筛选,用火焰分光光度法测定培养液和细茵细胞内的钾含量,以筛选出高效菌株.结果表明:dk8、dk7、dk14在解钾培养基上生长状况良好,以dk8分解钾长石的能力最强,可作为制作微生物肥料备选用菌.

| Abstract: | In this paper,we separated and purificated the bacteria for releasing insoluble potassium from soil by the selective medium in which potash feldspar power was treated as the only source of potassium.We diluted the bacteria with gradient and lined on culture plate for separation and purification of the bacteria for release potassium,and used flame spectrophotometer for tests potassium content in nutrient solution and the cell of bacteria,and then selscted high-efficiency bacteria.The results show that dk7,dk... |
