[0021] Preparation of the microbial fermentation composition: first mix the combined enzyme agent, the microbial mixed inoculum and water in the required proportions to form a degradation liquid, then add organic raw materials to the degradation liquid and mix to obtain the mixture, and then adjust the mixture The C / N mass ratio is 25-35:1, the initial moisture content is 50-60%, and the mixture is placed in a composting reactor for aerobic fermentation for 7-10 days to obtain a microbial fermentation composition. The temperature of the aerobic fermentation is maintained at 25-50°C. During the entire aerobic fermentation process, air with an oxygen concentration of 10%-20% is continuously introduced from the bottom of the composting reactor;
[0022] Preparation of organic fertilizer: firstly crush the microbial fermentation composition, and then mix it with urea in the required ratio.
[0023] The main raw materials used in the present invention are described as follows:
[0024] B...
Embodiment 1
