NOVELTY - Organic fertilizer comprises 12-16 pts. wt. sawdust, 8-10 pts. wt. borax, 5-8 pts. wt. plant ash, 1-12 pts. wt. rice husk, 8-12 pts. wt. peanut cake powder, 14-18 pts. wt. nano-iron ore tailing, 1-2 pts. wt. gelatin powder, 2-3 pts. wt. bio-fermentation agent, 3-5 pts. wt. magnesium sulfate, 4-6 pts. wt. ferrous sulfate, 4-5 pts. wt. monoammonium phosphate, 2-4 pts. wt. zinc chloride, 8-10 pts. wt. calcium-magnesium-phosphorus fertilizer, 4-5 pts. wt. auxiliary agent and water (suitable quantity).    USE - The organic fertilizer is useful for growing perennial climbers, preferably Polygonum multiflorum (claimed).    ADVANTAGE - The organic fertilizer reduces usage of chemical component, exhibits slow release effect, prevents soil compaction and is environmentally-friendly.    DETAILED DESCRIPTION - Organic fertilizer comprises 12-16 pts. wt. sawdust, 8-10 pts. wt. borax, 5-8 pts. wt. plant ash, 1-12 pts. wt. rice husk, 8-12 pts. wt. peanut cake powder, 14-18 pts. wt. nano-iron ore tailing, 1-2 pts. wt. gelatin powder, 2-3 pts. wt. bio-fermentation agent, 3-5 pts. wt. magnesium sulfate, 4-6 pts. wt. ferrous sulfate, 4-5 pts. wt. monoammonium phosphate, 2-4 pts. wt. zinc chloride, 8-10 pts. wt. calcium-magnesium-phosphorus fertilizer, 4-5 pts. wt. auxiliary agent and water (suitable quantity). The auxiliary agent comprises 1-2 pts. wt. zinc gluconate, 0.5-1.5 pts. wt. nanocarbon powder, 0.8-1.4 pts. wt. wintergreen oil, 2-3 pts. wt. medical stone powder, 0.5-1 pt. wt. ammonium persulfate, 1-5 pts. wt. nano-iron ore tailing, 3-5 pts. wt. methyl methacrylate, 4-6 pts. wt. borax, 2-3 pts. wt. glycerol and water (suitable quantity). The auxiliary agent is prepared by mixing the glycerol and water in a ratio of 1:8-10, adding zinc gluconate, nanocarbon powder, wintergreen oil, methyl methacrylate and ammonium persulfate, heating at 80-90 degrees C for 10-30 minutes, stirring, adding remaining raw materials, mixing to obtain paste, drying and crushing to obtain product. An INDEPENDENT CLAIM is included for method for preparing the organic fertilizer, which involves mixing the gelatin and water in a ratio of 1:150 under condition of heating and stirring, adding crushed borax to the water, heating at room temperature for 30-40 minutes under condition of stirring, cooling to room temperature, filtering to obtain a powder, mixing the sawdust, plant ash, rice husk, peanut cake powder and nano-iron ore tailing, adding the water until water content reaches to 30%, adding the bio-fermentation agent in a ratio of 1:10, spraying water to dissolve, mixing uniformly, fermenting at 35-40 degrees C for 10-15 days to obtain organic material, adding 1-14 times water to the remaining raw materials, stirring, heating, adding obtained powder and organic material, mixing, stirring, spraying water on obtained mixture, drying until water content reaches less than 18%, ultra-micro crushing, granulating granules with particle diameter of 3-5 mm, and bagging product.
