Abstract

The invention discloses a fermentation medium for improving phosphate-dissolving ability of bacillus cereus and a fermentation method thereof. The medium comprises 25-35g / L saccharose, 0.8-1.2g / L NH4Cl, 0.3g of NaCl, 0.3g of KCl, 0.03g of FeSO4.7H2O, 0.03g of MnSO4.H2O, 0.3g of MgSO4.7H2O, 2.0g of KH2PO4, and 1,000mL of distilled water, and the pH is 7.0-7.5. The invention also provides a fermentation method of the fermentation medium for improving phosphate-dissolving ability of bacillus cereus. By adopting the fermentation medium and the fermentation method, the bacillus cereus is in the optimal growth state, the preparation efficiency and the phosphate-dissolving effect of the phosphate-solubilizing bacteria inoculant can be effectively improved, the production cost of the bactericide is reduced, and plant growth is facilitated.

Description

technical field [0001] The invention belongs to the technical field of exploring the phosphorus-dissolving ability of bacillus cereus, and relates to a fermentation medium and a fermentation method for improving the phosphorus-dissolving ability of bacillus cereus. Background technique [0002] Phosphorus is an essential nutrient element for plant growth and development. Phosphorus deficiency can lead to a significant decrease in crop yields. Although the total phosphorus content in the soil is relatively high, it mostly exists in an insoluble state and is difficult to be absorbed and utilized by plants. In order to obtain high yield, a large amount of phosphorus fertilizers are repeatedly applied in production, about 70% of which are converted into insoluble compounds such as Ca-P, Fe-P and Al-P and stored in the soil, which not only depletes the limited phosphorus resources, but also causes Environmental pollution will also affect food safety and human health.
