Embodiment 1

[0056] Prepare the strain fermentation broth as follows:

[0057] a preparation of Bacillus cereus, Bacillus megaterium and Bacillus subtilis fermentation broth: Bacillus cereus CMCC63305, Bacillus cereus BS8641, Bacillus cereus AS2015, Bacillus megaterium ATCC10011 (B.megaterium), and Bacillus subtilis K-M (Bacillus subtilis) seed solution was inserted in the sterilized culture medium containing 5% bean sprouts juice, 0.5% glucose, 1.5% peptone, and the balance was water after 32 days in the ratio of 1:1:1:2:2. After 16 hours of aerobic fermentation at °C, the fermentation broths of Bacillus cereus, Bacillus megaterium and Bacillus subtilis were prepared.

[0058] b prepare Pantoea agglomerans fermented liquid: insert Pantoea agglomerans WLL (Pantoea agglomerans) seed liquid into the sterilized weight ratio of soybean flour 1%; corn flour 2%; yeast extract 0.5%; sugar 1%, monosodium glutamate 0.3%; Potassium dihydrogen phosphate 0.1%, Calcium carbonate 1%; Sodium chloride 0....

Embodiment 2

[0062] Prepare the strain fermentation broth as follows:

[0063] a prepare Bacillus cereus, Bacillus megaterium and Bacillus subtilis fermentation broth: Bacillus cereus CMCC63305, Bacillus cereus BS8641, Bacillus cereus AS2015, Bacillus megaterium ATCC10011 (B.megaterium), and Bacillus subtilis K-M (Bacillus subtilis) seed liquids were independently inserted into the sterilized culture medium of 8% bean sprouts juice, 0.3% glucose, 1.05% peptone, and the balance was water, and passed the conditions of pH7.8 at 34°C. After 20 hours of aerobic fermentation, the fermentation broths of Bacillus cereus, Bacillus megaterium and Bacillus subtilis were independently prepared;

[0064] B prepare Pantoea agglomerans fermented liquid: insert Pantoea agglomerans WLL (Pantoea agglomerans) seed liquid into the sterilized weight ratio of soybean flour 2%; corn flour 1.5%; yeast extract 0.3%; white sugar 2%, monosodium glutamate 0.2%; Potassium dihydrogen phosphate 0.2%, Calcium carbonate ...

Embodiment 3

[0068] The fermented liquid of Bacillus cereus prepared in Example 1, Bacillus megaterium, Bacillus subtilis, Bacillus jelly-like, Pantoea agglomerans is mixed according to the following weight ratio:

[0069] Bacillus cereus ATCC63305 5%

[0070] Bacillus cereus BS8641 5%

[0071] Bacillus cereus AS2015 5%

[0072] Bacillus megaterium ATCC10011 10%

[0073] Bacillus subtilis K-M 10%

[0074] Bacillus jelly-like ATCC10013 20%

[0075] Pantoea agglomerans WLL 20%

[0076] Azotobacter rotundum ATCC10003 25%

[0077] Then pack and make microbial fertilizer of the present invention.

Abstract

The invention relates to a microbial fertilizer and a preparation method thereof. The preparation method is as follows: bacillus cereus, bacillus megaterium and bacillus subtillis are mixed and fermented; bacillus mucilaginosus, pantoea agglomerans and azotobacter chroococcum are fermented respectively; the four fermented cultures are mixed and filled according to a certain proportion so as to produce a microbial blend which is used by the methods of seed soaking, root irrigation and spraying. The microbial fertilizer can promote plant rhizosphere growth and propagation, improve soil, eliminate soil hardening, enhance soil permeability and promote the development of the root system; the microbial fertilizer has the advantages of releasing potassium and phosphorus, fixing nitrogen, improving fertilizer efficiency and reducing the amount of chemical fertilizer used, inhibiting the propagation of harmful bacteria in the soil, preventing the diseases such as soil-borne diseases, replant disease and the like; thus realizing the functions of increasing income and improving the quality of agricultural products.

Description

technical field [0001] The invention relates to a microbial fertilizer and a preparation method thereof. Background technique [0002] The source of modern human food depends on agricultural production as the primary industry. Due to the explosive growth of the world's population, it is impossible to produce enough food to meet human needs only by relying on the basic fertility of the soil to provide nutrients. Therefore, we must use a lot of fertilizers in agricultural production. In addition to the limited organic fertilizers that nature can provide, it is more important to rely on chemical fertilizers at present. my country's current chemical fertilizer use per unit area is more than three times the average level of the United States and the world. The total annual use exceeds 120 million tons, and the loss rate of nitrogen fertilizers is as high as 45%, which means an annual loss of more than 100 billion yuan and a large amount of Energy is destroyed and the environmen...
