Method for preparing fungus pack waste organic fertilizer

The invention discloses a method for preparing fungus pack waste organic fertilizer. The method comprises the steps that 1, 100-300 parts of fungus pack waste, 20-30 parts of biogas slurry, 50-80 parts of cow dung and 10-15 parts of waste vegetables are mixed, an appropriate amount of water is added, and the mixture is stacked and fermented for 20-30 days; 2, 1-3 parts of maize flour, 0.1-0.2 partof brown sugar and 0.1-0.2 part of fresh ginger are added into the preliminarily-fermented stack and mixed to be uniform, and the mixture continues to be stacked and fermented for 5-8 days; 3, finally, 5-10 parts of calcium oxide is scattered on the surface of the surface of the fermented stack, the mixture is stacked for 3 days, mixed to be uniform, dried and prepared to be powder, and thereforethe fungus pack waste organic fertilizer is obtained. The fungus pack waste is adopted as the main raw material to produce the organic fertilizer, biogas slurry, cow dung, maize flour, calcium oxide,brown sugar, waste vegetab
