The invention discloses a carbon-based compound
fertilizer containing
probiotic organisms. The carbon-based compound
fertilizer comprises
biomass carbon black and probiotics, wherein the
biomass carbon black is prepared by the following method: carrying out low-temperature
carbonization on agricultural wastes as
biomass raw materials to form porous
biomass carbon black. The probiotics are prepared by the following method: carrying out amplification culture on beneficial microorganisms and fermenting to form
probiotic liquid; and mixing and then carrying out
solid-liquid separation and expansion
drying to form the probiotics, wherein the beneficial microorganisms are selected from one or more of peanibacillus ploymyxa,
trichoderma,
nitrogen-fixing
bacteria,
root nodule bacteria,
phosphate-solubilizing
bacteria,
potassium bacteria,
cellulose decomposition bacteria, antibiotic-producing strain and
photosynthetic bacteria. The carbon-based compound
fertilizer disclosed by the invention is made of microporous
biomass carbon, and thus the carbon-based compound fertilizer has extremely-strong adsorption capacity and favorable light absorbing and temperature increasing effects; in addition, the probiotics of the carbon-based compound fertilizer are high in
cell viability; and the carbon-based compound fertilizer can be preserved at normal temperature for a long time, can be mixed, granulated and dried with other organic and inorganic fertilizers without being influenced and is remarkable in synergistic action.
