[0026] Example 1
[0027] A biological bacterial fertilizer prepared by using waste diatomaceous earth from a brewery is prepared by a production method in the following steps:
[0028] 1. Pretreatment of waste diatomite
[0029] Dry the waste diatomaceous earth of the brewery, and the final moisture content is 50%-60%.
[0030] 2. Preparation of mixed bacterial liquid:
[0031] Cultivate the biocontrol bacteria Bacillus licheniformis ABTNL-1 and Bacillus subtilis ABTNL-2 with liquid medium, and mix them in equal proportions to prepare a mixed bacterial solution;
[0032] The liquid medium is prepared with 10.0g of sodium chloride, 10.0g of tryptone, and 5.0g of yeast powder dissolved in 1L of distilled water, sterilized at 121℃ for 20 minutes, and used; the concentration of bacteria in each biocontrol bacteria solution is 10 8 -10 9 CFU·ml -1 .
[0033] 3. Fermentation and condition control
[0034] Inoculate the mixed bacterial solution of biocontrol bacteria: inoculate the mixed bacter...
