Preparation method of kitchen organic liquid fertilizer and application of kitchen organic liquid fertilizer in agriculture and forestry production

The invention relates to the technical field of kitchen waste recycling, and provides a preparation method of a kitchen organic liquid fertilizer and application of the kitchen organic liquid fertilizer in agriculture and forestry products.The preparation method of the kitchen organic liquid fertilizer comprises the following steps that S1, after kitchen waste is subjected to oil-water separation, the kitchen waste is subjected to bacterial degradation, and bacterial degradation liquid is obtained; s2, filtering and washing the bacterial hydrolysate to obtain a bacterial hydrolysate diluent; s3, adding compound amino acid and/or compound strains into the bacterial degradation diluent for aeration treatment to obtain the kitchen organic liquid fertilizer, the composite strain comprises bacillus subtilis GN19. By means of the technical scheme, the problems that in the prior art, kitchen waste is not prone to being recycled into water-soluble fertilizer, and the plant growth promoting effect is poor are solved.
