Embodiment 1
[0033] The preparation of embodiment 1 fermentation bacterial agent
[0034] The strains used in this example are all listed in the public strain catalog of China General Microorganism Strain Collection and Management Center (Beijing), and can be purchased. The catalog numbers of each microorganism and its strains in the China Common Microorganism Culture Collection and Management Center are: Cellulomonas flavigena (No. 1.1002), Lactobacillus casei (No. 1.62), Vineland Azotobacter vinelandii (No. 1.1649), Rhizobium leguminosarum (No. 1.888), Aspergillus niger (No. 3.6193), Aspergillus oryzae (No. 3.481), Humicola insolens (Humicola insolens) (No. 3.4393), and Rhizopus oligosporus var. tuberosus (No. 3.1145). The above 8 strains were entrusted to Guangxi Yiduoshou Biotechnology Co., Ltd. through commercial channels to carry out liquid culture respectively according to the conventional strain culture method, and after centrifugation, the cells were preserved at 4°C and delivere...
Embodiment 2
[0038] The fermentation of embodiment 2 fulvic acid fertilizers
[0039] Pass the molasses alcohol fermentation waste liquid discharged from the sugar factory into the sedimentation tank, add NaOH solid to adjust the pH to 5.8, let it stand for 2 hours, and take the supernatant and sediment separately for use. Get 700kg cow dung and 300kg after pulverizing the sugarcane residue and 1kg embodiment 1 preparation of sugarcane residue and 1kg embodiment 1 and mix (do not add fermentation bacterium in the production of contrast fertilizer), then pass into above-mentioned stand-by supernatant 500L ( about 500kg), stirred evenly, piled into the fermenter and left to stand for 3 days, then added 300kg of sediment, and continued to stand for 12 days. During the standing period, the compost heap will naturally heat up. Measure the temperature inside the compost heap. When it exceeds 60°C, stir the compost heap to ventilate and cool down the compost heap. Stop stirring when the compost h...
