NOVELTY - A wine lees organic fertilizer comprises fermented material comprising 100 pts. wt. Lees, 3-5 pts. wt. knot rod, 1-2 pts. wt. wood, 2-2.5 pts. wt. quicklime and 0.2-0.3 strain. The strain is prepared by decomposing inoculant agent and dry weight for 2.5-3 times of chaff bran and uniform process activate and stirring, then adding decomposed inoculant agent comprising de-starch Bacillus and Bacillus mojavensis of dry weight of 4.5-5 times to saw wooden surface, stirring uniformly, and inoculanting valid viable count of more than 2x 108cfu/g.    USE - As organic fertilizer (claimed).    ADVANTAGE - The organic fertilizer made from lees production, short fermentation time, controllable degree of fermentation to obtain a product of organic matter, 76%, N, P2O5, K2O of 4%, 2.18%, and 1.29%, a total nutrient of 7.47%, pH of 6.2, water content of 29%, ascarid eggs and death rate and dung coliform flora number index of NY884.    DETAILED DESCRIPTION - A wine lees organic fertilizer comprises fermented material comprising 100 pts. wt. Lees, 3-5 pts. wt. knot rod, 1-2 pts. wt. wood, 2-2.5 pts. wt. quicklime and 0.2-0.3 strain. The strain is prepared by decomposing inoculant agent and dry weight for 2.5-3 times of chaff bran and uniform process activate and stirring, then adding decomposed inoculant agent of dry weight of 4.5-5 times to saw wooden surface, stirring uniformly, where decomposing inoculant agent mainly comprises de-starch Bacillus with preservation NO: of CGMCC No. 8143 and Bacillus mojavensis with preserving NO: of CGMCC No. 8268; and inoculanting valid viable count of more than 2x 108cfu/g. An INDEPENDENT CLAIM is included for preparation of the organic fertilizer involving: taking grain of one quantitative, uniform scattering a lees, 2-2.5% quicklime, 3-5% straw and 1-2% saw wooden surface, uniformly mixing to obtain fermented material; mixing bacteria strain according to mass 0.2-0.3% with uniform scattering ratio of fermenting material; regulating and mixing uniformly strain material, to build heaps; fermenting for 3-5 days, with heap temperature of up to 60-65 degrees C and growing stack with silk body, taking the first time, rear and after 2-3 days, heaps temperature again to 60-65 degrees C, grows a silk body, then turning process, fermenting for 8-10 days rear entering into ferment high temperature period, to maintain temperature heaps principle of not greater than 65 degrees C turning adjustment of a fermentation period for 20-25 days; rear ripe period of natural ventilation without turning to lasts for 1 to 2 months.
