| Summary: | Five bacterial strains with strong phosphate-solubilizing ability were mixed fermentation by C<sub>5</sub><sup>3</sup> composite design, and the co-fermentation systems consisted of the strains Bc, Bs, Ap<sub>1</sub> were obtained. The optimum inoculation in degradation of insoluble phosphate in soil was developed through orthogonal design, and the best inoculation ratio was Bc 2%, Bs 6%, Ap<sub>1</sub> 6%. It was a phosphate-dissolving bacteria agent that the three strains were inoculated in the phosphate-dissolving bacteria fermentation medium according to above-mentioned inoculation ratio and cultured at 30℃ and shaking speed 140 r·min<sup>-1</sup> for 28 h. Pot experiment results illustrated that the phosphate-solubilizing bacteria had a good advance on the plant height, root length and shoot fresh mass of Chinese cabbage. |
