The invention discloses a microbial carbon-based fertilizer as well as a preparation method and application thereof. Wheat straw biochar and rice hull biochar are screened as optimal biochar with the influence of biochar on the growth of bacillus amyloliquefaciens as an index, and the physicochemical properties of the biochar are measured. It is discovered through further condition optimization that the optimal particle size of adsorption of the two kinds of biochar to bacillus amyloliquefaciens B1408 (CGMCC No.15110) is 180-200 meshes, the optimal adsorption time is 48 hours, the optimal oscillation speed is 170 rpm/min, and the optimal ratio of the bacterial suspension to the biochar is 20: 1. Then, two technological processes of adsorption and blending are adopted for exploration, and four bacillus amyloliquefaciens B1408 microbial carbon-based fertilizers including wheat charcoal adsorption B1408 (WSBX), wheat charcoal blending (WSBC), rice charcoal adsorption (RSBX) and rice charcoal blending (RSBC) are
