In order to verify the effect of different adsorption carriers and dosage forms of solubilizing phosphobacteria on the improvement of phosphorus status,low and high phosphorus soil were selected in this indoor culture experiments. The results showed that for low phosphorus tested soil,the better dosage forms and formulations to improve the effect of soil available phosphorus content were formulation 4 ＞ formulation 3 ＞ formulation 2 ＞ liquid dosage form ＞ formulation 1 ＞ formulation 2. Compared with the control,the average content of soil available phosphorus increased 11.22 mg/kg,9.43 mg/kg,7.34 mg/kg,4.36 mg/kg and 3.38 mg/kg in the soil cultivation process of 30 days,60 days,90 days,and 120 days. While for high phosphorus tested soil,the result was formulation 3 ＞ formulation 1 ＞ formulation 2 ＞formulation 4. Compared with the control,the average content of soil available phosphorus increased 10.37 mg/kg,7.83 mg/kg,3.99 mg/kg and 3.08 mg/kg. The effect of the liquid dosage form was not significant. For two soils of different fertility,there were some differences in the effect of dissolved phosphorus among different adsorption carrier formulations and dosage forms. And soil phosphorus nutritional status has a certain impact for the dissolved phosphorus effect of the bacterial agent. The higher soil available phosphorus background value,the worse effect of the dissolved phosphorus.
