NOVELTY - Slow release fertilizer comprises component A comprising urea, cellulose, tea seed cake, carbon black, polyvinyl alcohol, diammonium phosphate, potassium sulfate, potassium chloride, modified plant ash, sweet potato leaf, mushroom residue, distillers grains, water-soluble phenolic resin, zinc sulfate, and ferrous sulfate, and component B comprising pond sludge, acrylic emulsion, ethyl acetate, acrylic acid, amino acid, calcium powder, alpha -naphthalene, gluconolactone, trace element fertilizers, montmorillonite, and potassium silicate.    USE - Used as a slow release fertilizer.    ADVANTAGE - The slow release fertilizer has high plant lodging resistance, drought resistance and plant absorbing rate, and increased dispersibility and fertility.    DETAILED DESCRIPTION - Slow release fertilizer comprises (in pts. wt.): component A comprising urea (20-30); cellulose (5-10); tea seed cake (15-25); carbon black (10-15); polyvinyl alcohol (3-5); diammonium phosphate (3-5); potassium sulfate (2-5); potassium chloride (2-5); modified plant ash (5-10); sweet potato leaf (3-8); mushroom residue (8-12); distillers grains (3-5); water-soluble phenolic resin (2-4); zinc sulfate (5-10); and ferrous sulfate (3-8); and component B comprising pond sludge (10-20); acrylic emulsion (5-10); ethyl acetate (3-5); acrylic acid (3-5); amino acid (3-5); calcium powder (3-5); alpha -naphthalene (0.8-1.2); gluconolactone (0.3-0.5); trace element fertilizers (0.2-0.4); montmorillonite (5-10); and potassium silicate (3-5). An INDEPENDENT CLAIM is included for preparing slow release fertilizer comprising (1) weighing the raw material, adding the component A and B into a stirrer and then fully mixing, (2) primary fermenting the components A for 8-10 days and then controlling the fermentation temperature to 50-60 degrees C, where the component A has a water content of 45-55%, and a pH value of 5-6, and (3) mixing the component A and B and then secondarily fermenting for 7-9 days and then controlling the fermentation temperature to 65-75 degrees C and then granulating.
