NOVELTY - Preparation of an adult oil tea organic-inorganic special fertilizer, involves taking camellia and tea powder, crushing, stirring and mixing, adding bio-active base material and water; fermenting the mixture at more than 60 degrees C for 30-35 days, drying to form biological organic fertilizer; and mixing the biological organic fertilizer with urea, monoammonium phosphate, calcium-magnesia phosphate, potassium sulfate, potassium oxide, zinc sulfate and borax, and adding water and stirring, to form organic-inorganic special fertilizer.    USE - For the preparation of an adult oil tea organic-inorganic special fertilizer (claimed).    ADVANTAGE - The fertilizer solves the problem of organic fertilizer survival rate and fertilizer supply intensity; improves the yield of tea seed oil; and provides oil of high quality.    DETAILED DESCRIPTION - Preparation of an adult oil tea organic-inorganic special fertilizer, involves taking camellia (69-71 wt.%), and tea powder (24-25%), crushing into 50-80 meshes, stirring and mixing the raw materials, and then adding bio-active base material (4.5-5.5 wt.%), adding water for uniformly stirring, controlling moisture of the material at 50-55 degrees C; fermenting the mixture at more than 60 degrees C for 30-35 days, keeping the water content of the 50-55%, finally naturally drying to form biological organic fertilizer, where the obtained biological organic fertilizer has organic matter content of 55-60%, nitrogen content of 3.5-4.5%, P2O5 content of 1.5-2.5%, K2O content of 1.5-2.5%; and mixing the biological organic fertilizer with urea (41.5-42.5 wt.%), monoammonium phosphate (23.5-24.5 wt.%) (containing 50% of phosphorus pentoxide, and 10% of nitrogen), calcium-magnesia phosphate (3.5-4 wt.%) (containing 18% of phosphorus pentoxide, 25% of calcium oxide, and 14% magnesium oxide), potassium sulfate (12.5-13.5 wt.%), 50% of potassium oxide (14-15 wt.%), zinc sulfate (0.75-0.85%), and borax (1.1-1.3 wt.%), and adding water and stirring uniformly, to form organic-inorganic special fertilizer having organic matter content of 24-26%, nitrogen content of 12.5-13.5%, P2O5 content of 4.5-5.5%, K2O content of 7.5-8.5%, zinc sulfate (0.75-0.85%), borax (1.1-1.3%), calcium oxide (3.1-3.5%), and magnesium oxide (1.65-1.75%).
