Abstract:
The experiment was conducted to study the phosphoru bacterial strains from the rhizosphere soil of the single sunflower,wheat and leguminosae planting areas by plate P-solubilizing circle method.Three phosphate-solubilizing bacterial strains including JLX-1,JLX-2 and JLX-3 were obtained from all kinds of corps soil to investigate the effects of different and JLX3 were abtained from all kinds of crops soil to investigate the effects of different conditions on Psolubilizing capacity.The results showed that the JLX-3 strains showed strong ability of dissolving phosphate with a ratio of dissolving phosphate zone diameter to culture community zone diameter (D/d) 2.09.When the carbon source was glucose,nitrogen source was (NH4)2SO4,the phosphate-solubilizing capacity were 5.572 mg?g-1 and 5.520 mg?g-1,respectively.The JLX-3 displayed a better phosphate solubilizing capability when NaCl concentration was 0.3 g?L-1 and pH was 7.The based on the morphological physiological and biochemical properties JLX-3 was identified as Bacillus.
