Example Embodiment
[0018] The present invention will be described in detail below in conjunction with 6 examples, but the present invention is not limited to the given examples.
[0019]
[0020] In the example, the EM stock solution, honey and water are mixed first, and then 10% calcium sulfate suspension is added to the mixed solution, and placed in a rotary shaker with a speed of 120r / min~180r / min under airtight conditions. It is made by anaerobic fermentation for 3-5 days, standing and filtering, and concentrating the filtrate. Measured by the method provided by the NY / T789-2004 (Composite Microbial Fertilizer) standard, the pH of the concentrated solution of the composite microbial calcium preparation prepared in each example is 6.0-7.5, and the effective viable cell count (CFU) is greater than 100 million / ml. The calcium content is 0.5%-1.0%.
[0021] In the process of compound microbial fermentation, the role of honey is to provide C source and energy for the rejuvenation and metabolism of mi...
