NOVELTY - Processing and applying agricultural solid waste by aerobic high-temperature hydrolysis fermentation, comprises: (i) mixing crop straw after cutting and shearing with poultry and animal feces, separating liquid and solid components in mixture by pressing; (ii) mixing pressed liquids, adjusting pH value, vaccinating activated sludge, performing hydrolysis fermentation on mixed sludge, fermenting, vacuum concentrating and cooling to obtain composite microbial agents product; and (iii) performing hydrolysis fermentation on pressed residue of step (i), fermenting, drying, cooling and packaging.    USE - The method is useful for processing and applying agricultural solid waste by aerobic high-temperature hydrolysis fermentation.    ADVANTAGE - The method: completely utilizes large amount of agricultural crop straw, and poultry and animal feces for industrial production, thus recycling many agricultural organic wastes; and is environment-friendly.    DETAILED DESCRIPTION - Processing and applying agricultural solid waste by aerobic high-temperature hydrolysis fermentation, comprises: (i) mixing crop straw after cutting and shearing with the poultry and animal feces in a weight ratio of 1:6-5:2, then separating the liquid and solid components in the mixture by pressing, soaking the solid residue for 12-72 hours after pressing and then pressing again for separating the liquid and solid; (ii) mixing the pressed liquids of the above step, adjusting the pH value with acetic acid or lime water, where the pH value is 4.5-8.5, vaccinating activated sludge having a weight of 0.1-0.3% of pressed mixture, performing hydrolysis fermentation on the mixed sludge in presence of hot air at 40-70 degrees C, controlling the inner temperature of the fermenting liquid at 30-60 degrees C, fermenting for 1-10 days as a cycle, vacuum concentrating and cooling to obtain composite microbial agents product; and (iii) adjusting the pH value of the residue obtained in step (i) with acetic acid or lime water to 4.5-8.5, where the water content is 50-60 wt.%, performing hydrolysis fermentation on the pressed residue in presence of hot air at 40-70 degrees C, controlling the inner temperature of the pile at 30-60 degrees C, fermenting for 1-10 days, then drying with hot air at 50-60 degrees C till the water content is 40-60 wt.% and cooling, and packaging to obtain the low humus carbon source organic product in stable state.
