土钵培养法筛选硅酸盐细菌

30种硅酸盐细菌菌株用土钵培养法进行筛选，分别在培养30、60、90、180d用火焰光度计测定土壤中钾离子含量；在所有研究的30种菌株中，菌株新6在土钵培养60d后检测出最高的土壤有效钾净增率22．1％；菌株F1具有最高的总土壤有效钾净增率20％；对土壤总有效钾含量进行统计学分析，筛选出14种菌株具有显著的解钾能力。

Screening silicate bacteria by the cultivation of earthen bowl

Abstract: Screening 30 strains of silicate bacteria by cultivation of earthen bowlwas conducted, after cultiva2 ting 30 days, 60 days, 90 days and 180 days respectively, potassium ion concentration was measured by flame spectrometry. In all 30 strains, effective potassium ion concentration in soil reaches 22. 1% in the cultivation of strain Xin 6, the total effective potassium ion concentration in soil reaches 20% in the cultivation of strain F1. Sta2 tistics analysiswas conducted on total effective potassium ion concentration of the soil, 14 strainswhich had obvious potassium melting ability were screened.
