NOVELTY - Composting method of organic-inorganic compound fertilizer specific for vegetable, involves uniformly mixing fresh, shard and cut taro straw, adjusting carbon and nitrogen ratio, piling mixture into cone, turning the cone once for every seven days, obtaining organic fertilizer, drying organic fertilizer, pre-drying calcium superphosphate, crushing calcium superphosphate, mixing crushed product with organic fertilizer, granulating the obtained product, and obtaining the organic-inorganic compound fertilizer.    USE - The method is useful for composting organic-inorganic compound fertilizer specific for vegetable.    ADVANTAGE - The composite fertilizer is economic, scientifically adjusts nitrogen, phosphorus and potassium ratio, increases vegetables yield, and improves vegetable quality.    DETAILED DESCRIPTION - Composting method of organic-inorganic compound fertilizer specific for vegetable, involves uniformly mixing fresh, shard and cut taro straw in the weight ratio of 2-3:1, adjusting carbon and nitrogen ratio to 25, maintaining the moisture content of the mixture to 60%, piling the obtained mixture into cone shape having 1.5 m height, supplying oxygen to the obtained product, maintaining the stack central temperature at 55 degrees C, turning the cone once for every seven days, using the seed germination index to indicate the rotten degree, obtaining the organic fertilizer, drying the organic fertilizer, pre-drying calcium superphosphate, crushing the calcium superphosphate, mixing the crushed product with organic fertilizer, where the weight ratio of the organic fertilizer is 40%, urea is 13.37%, calcium superphosphate is 34.72%, potassium chloride is 11.91%, pelletizing the obtained mixture, granulating the obtained product, where the particle diameter of the granulated product is 100 meshes or less, adding bentonite to the obtained granules to improve physical performance of the surface of the granules, and obtaining the organic-inorganic compound fertilizer.
