NOVELTY - A cage egg henhouse ferment pad material utilizing method involves mixing dry sawdust and dry rice hull. The mixture is fermented and added with chicken manure. Water dissolved with Bacillus subtilis is added in the material. Stacking fermentation process is performed. The fermented pad material is transported to a cage egg henhouse for groove type oxygen fermentation. Scarifying process is performed for the material. The material is oxygen fermented, and fully cured. The fermented material is repeatedly processed for stacking fermentation. The material is dried to obtain fertilizer.    USE - Method for utilizing a cage egg henhouse ferment pad material to manufacture organic fertilizer.    ADVANTAGE - The method enables obtaining high-efficient organic fertilizer, improving environment in the henhouse, cleaning and transporting the chicken manure in a harmless way, utilizing the pad material in an environmental-friendly manner, and satisfying poultry sustainable development requirement.    DETAILED DESCRIPTION - A cage egg henhouse ferment pad material utilizing method involves uniformly mixing 8-10% water content of dry sawdust, and 8-10% water content of dry rice hull according to weight ratio of 1:1. The mixture is fermented, and 60-75% water content of fresh chicken manure is added to the mixture, where composition contains (in weight parts) dry sawdust (42-45), dry rice hull (42-45) and fresh chicken manure (10-15). A ferment strain Bacillus subtilis is dissolved in the water, where adding amount of the Bacillus subtilis is 0.08-0.2% of the water content. The water dissolved with the Bacillus subtilis is added in the material composition, where mass ratio of the water to the material composition is 1:1. The material and the water are uniformly mixed and stacked together. Stacking fermentation process is performed, where the fermentation process is finished when stacking fermentation temperature is naturally warmed to 70 degrees C. The temperature is maintained over than 70 degrees C for 2 days. The fermented pad material is transported to a cage egg henhouse to proceed groove type oxygen fermentation, where thickness of the fermentation pad material is 30-50 cm, and chicken density on the fermentation pad material is 32 chickens on each square meter ferment slot. The water content is controlled at 40-50% during the fermentation process. Scarifying process is performed for the ferment pad material to make chicken manure to fall on the pad material. The ferment pad material in the cage henhouse is oxygen fermented for 1.5-3 months. The oxygen fermentation is completed, and the ferment pad material is fully cured. The fermented material is cleaned out of the henhouse to process stacking fermentation again. The stacking fermentation process is finished when stacking fermentation temperature is naturally warmed to 70 degrees C, and the temperature is maintained over than 70 degrees C for 2 days. The material is dried until the moisture content becomes less than or equal to 20% to obtain the organic fertilizer.
