NOVELTY - Fermenting animal manure includes preparing additive material and chicken manure, separating additive material, and dividing the chicken manure into five equal parts; selecting flat and high platform; uniformly composting the mixture of strain, stirring uniformly, and stirring the chicken manure; after the ferment compost is finished, putting the chicken manure into the first fermentation stage, fermenting, adding mixture strain, and stirring uniformly; and drying the fermented finished product, crushing and sieving, the screen coarse repeated crushing, sieving, and packaging.    USE - Method for fermenting animal manure used for organic fertilizer (claimed).    ADVANTAGE - The method can improve crop quality.    DETAILED DESCRIPTION - Fermenting animal manure comprises:    (A) preparing additive material and chicken manure, separating additive material, and dividing the chicken manure into five equal parts;    (B) selecting flat and high platform, digging parallel ventilation channel, where furrow is 30 cm, the depth is 30 cm, and the beam width is 20 cm, paving straw on the crossbeam upper groove to form one bottom ventilating fermentation platform which is convenient for ventilating oxygen supply;    (C) uniformly composting the mixture of strain, stirring uniformly, stirring the chicken manure water content adjusted to 50%;    (D) after the ferment compost is finished, putting the chicken manure into the first fermentation stage, automatically raising to more than 55 degrees C, keeping for 5-7 days, and fermenting for 7-10 days, naturally reducing to less than 50 degrees C, adding mixture strain, stirring uniformly, controlling the water to below 50 degrees C, after 10-20 days, reducing the compost temperature to less than 40 degrees C and the second time ferment temperature to 40 degrees C, which reaches the standard decomposed; and    (E) drying the fermented finished product, crushing and sieving, the screen coarse repeated crushing, sieving, and packaging.
