The invention discloses high-efficiency biological organic fertilizer for organic crops. The high-efficiency biological organic fertilizer is characterized in that raw materials for preparation include strains and organic matter and minerals, the strains include enzyme bacterium, EM bacterium, photosynthetic bacterium, lactic acid bacterium and phosphorous-dissolving potassium-dissolving nitrogen-fixing composite bacterium, and the organic matter and minerals include chicken manure, soybean powder or blood powder, bone powder or phosphorite powder, palm ash or potassium feldspar, zeolite powder, medical stone powder, humic acid, rare earth, carbonized bacterium stick powder, crab shell, rice bran, fish meal and brown sugar. Nutrition facts of the high-efficiency biological organic fertilizer can meet needs of crop growing, the fertilizer can be applied once for all, and additional fertilizing is not needed. After soil environment is improved for two to three years, diseases and pests are reduced and disappear gradually, and insecticide application is not needed afterwards, so that organic planting is realized truly while processed agricultural products are organic products indeed.
