NOVELTY - Preparation of peanut organic fertilizer includes mixing animal manure, corn straw charcoal and water into reactor to obtain first mixture; mixing oil shale ash, ferrous sulfate, citric acid, manganese sulfate, potassium magnesium fertilizer, ammonium molybdate and borax into mixer to obtain second mixture; dissolving second mixture in water, adding first mixture, mixing with rapeseed, fermenting, adding bacteria, and fermenting; mixing with burned honeycomb, air-drying, and crushing; and adding dicyandiamide powder, polyvinyl alcohol, urea and remaining second mixture, and mixing.    USE - Method for preparation of peanut organic fertilizer (claimed).    ADVANTAGE - The fertilizer satisfies peanut nutrient requirement for growing period, and it has easy to obtain raw material, low cost, high utilization rate of nitrogen, phosphorus and potassium element, and good slow release ability.    DETAILED DESCRIPTION - Preparation of peanut organic fertilizer comprises:    (A) mixing 20-40 pts. wt. animal manure, 15-30 pts. wt. corn straw charcoal and 15-20 pts. wt. water into reactor at 85-95 degrees C, and cooling to obtain first mixture;    (B) mixing 1-2 pts. wt. oil shale ash, 1.5-3 pts. wt. ferrous sulfate, 2-4 pts. wt. citric acid, 1-2 pts. wt. manganese sulfate, 1.2-1.7 pts. wt. potassium magnesium fertilizer, 0.25-0.5 pts. wt. ammonium molybdate and 1-3 pts. wt. borax into mixer at 65-75 degrees C to obtain second mixture;    (C) dissolving 15-20 wt.% second mixture in water to obtain 0.35-0.47 wt.% mixed solution, adding first mixture, mixing with 80-120 wt.% rapeseed, fermenting to 30-35 degrees C for 1-2 days, adding bacteria, and continuously fermenting for 2-4 days to obtain third mixture;    (D) mixing with 15-20 wt.% burned honeycomb, air-drying to room temperature under dark environment condition for 7-8 days, and crushing to obtain fourth mixture; and    (E) adding 6-8 pts. wt. dicyandiamide powder, 1-4 pts. wt. polyvinyl alcohol, 18-20 pts. wt. urea and remaining second mixture, mixing, crushing, and sieving.
