The invention relates to a preparation method of a carbon-sequestration and emission-reduction bio-organic fertilizer. The preparation method comprises the following steps: crushing straws to 30-50 meshes; taking the following raw materials in parts by weight for anaerobic fermentation: 60-150 parts of livestock and poultry manure, 2-3 parts of white-rot fungi, 1-2 parts of saccharomycetes, 2-5 parts of phosphoric acid, 0.2-0.6 part of aspergillus niger and 1-10 parts of biogas residues; uniformly mixing the biogas residue compound, biochar, diammonium phosphate, urea, potassium sulfate, protease, bacillus subtilis, distillers' grains, a dispersing agent and a coating material to obtain a composite material, and crushing the composite material to obtain the biogas residue fermentation compound fertilizer. The organic compound fertilizer fully utilizes residual straws and biogas residues, and has the advantages of slow release of the fertilizer, soil improvement, carbon sequestration, emission reduction and th
