The invention provides an environment-friendly bio-fertilizer and a preparation method thereof. The environment-friendly bio-fertilizer comprises the following components in percentage by weight: 0.01-0.02% of a deodorization decomposition agent, 4-6% of humic acid, 0.1-0.2% of composite EM (Effective Microorganism) bacterium agent, 0.1-0.2% of sugar, 0.005-0.01% of microelement and the balance of a bio-fertilizer backing material, wherein the humic acid is used for increasing the organic content of biologic fermented manure, and adjusting the pH value; the composite EM bacterium agent is microbial flora containing photosynthetic bacteria flora, lactic acid bacteria flora, saccharomycetes flora and gram flora which are beneficial for soil and crops. The invention further discloses the preparation method of the environment-friendly bio-fertilizer. The environment-friendly bio-fertilizer has the benefits that the pollution is reduced, wastes can be reused, the environment is protected, and the efficiency is high. |
