Abstract:
Microorganism impacts greatly on the translation and the availability of phosphorus in the soil. Inoculating the medium with Ca3(PO4)2 and lecithin as the only P source respectively with the strains of bacterial fertilizer in our laboratory, 9 strains of phosphorus-dissolving bacteria were selected. The contents of available phosphorus increased from 33.082 mg·kg-1 to 344.820 mg·kg-1 in the medium withCa3(PO4)2 and increased from 0.870 mg·kg-1 to 43.123 mg·kg-1 in the medium with lecithin. The pH of all cultures of the medium with Ca3(PO4)2 were lower than that of CK. While in cultures of the medium with lecithin, the pH values of 7 strain cultures were lower than that of CK and the other 2 strains were higher. The pH varied in 5.0~7.5.
Key words: bacterial manure, inorganic phosphorus, organic phosphorus, phosphorus-dissolving bacteria, available phosphate, P-release
