Abstract：The proportion and phosphate-dissolving effect of compound microorganisms which were composed of Aspergillus niger ,lactic acid bacteria and acetic acid bacteria and Bacillus megaterium were studied .The results showed that the optimal proportion of compound microor-ganisms was as follows :Aspergillus niger 5% ,lactic acid bacteria 4% ,acetic acid bacteria 3% and Bacillus megaterium 5% .Under this condition ,the content of dissolved phosphorus was 2 442 .50 mg/kg ,and the phosphorus conversion rate reached 78 .7% ,which was better than the single strain .
