NOVELTY - Method for chicken manure deodorization and in-advance composting in off-ground stable breeding house, involves mixing pine sawdust and crushed straw, mixing the liquid containing effective microorganisms (EM) and water to obtain microbial solution, paving a layer of obtained mixture on the ground of the breeding house, spraying a layer of microbial solution to the layer paved with mixture, adding chicken manure, piling and completely sealing with thick plastic film, adding the next batch of the chicken manure, processing, and composting the manure.    USE - The method is useful for chicken manure deodorization and in-advance composting in off-ground stable breeding house (claimed).    ADVANTAGE - The method is suitable for small and medium-scale chicken house, fully utilizes the chicken house, saves space and the time required by composting manure outside the house, shortens the forming period of the manure, reduces the manure cleaning times of breeders, and influence on the health of chicken and the breeders caused by odor volatilization in the house, and is environmentally-friendly and capable of meeting the requirements of deodorization in the chicken house and composting in advance.    DETAILED DESCRIPTION - Method for chicken manure deodorization and in-advance composting in off-ground stable breeding house, involves (a) controlling water content of dry maize straw or wheat straw to less than 10 wt.%., crushing the straw using machine or cutter to a length of less than 3 cm, controlling the water content of the pine sawdust to 7 wt.% or less, and mixing the pine sawdust and crushed straw in a weight ratio of 7:2-3, (b) mixing the liquid containing effective microorganisms (EM) and water in a volume ratio of 1:15-20 to obtain microbial solution, where the viable count of microbial cell in the solution is more than 3 billion colony-forming unit (CFU)/ml and the cells are counted using microscope, (c) paving a layer of mixture obtained in the step (a) on the ground of the chicken breeding house to a thickness 2-3 cm, spraying a layer of microbial solution to the upper portion of the layer paved with mixture for 2 days, uniformly covering the layer with the mixture to thickness of 2-3 cm, continuously spraying the solution for 2 days, and covering the layer with the mixture, repeating covering and spraying steps for first 6 days, finally spraying the microbial solution on the mixture, adding chicken manure at the same side of the stack ground, piling such that the bottom width is 1-2 m, the top width is 0.5-1 m and the height of the pile from the rack or cage is 10 cm, and completely sealing with thick plastic film, (d) adding the next batch of the chicken manure, processing the manure, at the same time maintaining humidity and ventilation, housing all the ground pile and the scattered chicken manure, and uniformly cleaning, and (e) remixing different pile and manure, newly piling and maintaining the temperature, water content and pH of the new pile at 45-50 degrees C, 50-60% and 6-8, respectively, sealing with plastic film, and composting the chicken manure for 30-40 days.
