Total-element compound microorganism organic fertilizer comprises, by weight, 40-60 parts of bacillus, 4-6 parts of actinomycetes and 30-50 parts of chemical fertilizer. The bacillus is composed of bacillus subtilis, bacillus licheniformis, bacillus mucilaginosus, bacillus pumilus and bacillus megatherium. The chemical fertilizer contains oxygen, phosphorus and potassium. The invention further provides a preparing technology of the organic fertilizer. The preparing technology is simple, feasible, scientific, reasonable and suitable for industrial production. The prepared organic fertilizer integrates efficiency increasing of bio-fertilizer, long acting of organic fertilizer and quick acting of chemical fertilizer, the disease resistance, drought resistance and the low-temperature resistance of crops can be enhanced, the soil is loosened, and the hardening is removed; acid bases are conditioned, and the soil is repaired; residues are degraded, and the field is purified; the fertilizer efficiency is improved, and cost is reduced; the disaster is resisted, and stable yields despite drought or excessive rain are ensured; early maturing, quality upgrading and other metabolism mechanisms are promoted, the high yield of crops is increased, the quality of the crops is improved, and the economic income and social benefits of farmers are increased.
