In this experiment, the ability of 38 rhizosphere bacteria strains of Curcuma wenyujin to dissolve phosphorus, synthesize IAA, and inhibit pathogens were tested. Twenty five strains secreted >1 mg·L^-1 IAA, 23 strains produced >10 siderophores, 10 strains dissolved > 2 mg·L^-1 phosphorus, and 3 strains showed inhibitory effect on four plant fungal pathogens. Finally, three strains were selected for a pot experiment. Strain WP0702 secreted a high siderophore concentration and inhibited the growth of pathogens. Strain WK0101 secreted high concentrations of both siderophore and IAA, dissolved a large amount of phosphorus, but showed no bacteriostatic?ability. The two strains clearly promoted the yield of Curcuma wenyujin. It indicated that the strains that have the ability to dissolve phosphorus, secret IAA, and inhibit fungal pathogens have potential to be used as biological fertilizers. Strain WP0702 labeled with the marker gene LuxAB could survive in different soils. Both WP0702 and WK0101 have potential to be a specific biological fertilizer for Curcuma wenyujin.
