The invention relates to a biological composite bacterium fertilizer and belongs to the field of bio-fertilizer. A special biological composite bacterium fertilizer for platycodon grandiflorum is composed of the following components in percentage by weight: 5-10% of bactericide, 55-60% of macromolecule natural organic matter, 10-13% of large granular urea, 10-12% of controlled-release sulfur coated urea, and 5-15% of nitrogen-phosphorus-potassium compound fertilizer. The biological composite bacterium fertilizer provided by the invention has the advantages that the quantity and activity of the beneficial microorganism are improved, the harmful microorganism is inhibited, the physical and chemical properties of soil are improved, the nutrients of soil are increased and balanced, and the residues of farm chemicals and fertilizer and other harmful matters in the soil are degraded. After the biological composite bacterium fertilizer is applied, platycodon grandiflorum can be repeatedly planted in non continuous c
