An aerobic composting method for wood ear mushroom residue

A method for aerobic composting of Auricularia auricula-judae mushroom residue, relating to the field of Auricularia auricula-judae mushroom residue treatment, is disclosed to address the problems of slow temperature rise, insufficient composting, and unstable product quality associated with existing methods. The method comprises: 1. Mixing Auricularia auricula-judae mushroom residue, cow dung, and chicken dung to obtain a mixture; 2. Inoculating the mixture with lignocellulose-degrading bacteria; 3. Performing aerobic composting fermentation on the mixture after inoculation with lignocellulose-degrading bacteria, employing a staged intermittent composting process. This method promotes the composting and lignocellulose degradation of Auricularia auricula-judae mushroom residue, significantly increasing the composting rate, promoting the biotransformation of Auricularia auricula-judae mushroom residue, improving composting efficiency, and resulting in higher product quality stability. This invention is for the aerobic composting of Auricularia auricula-judae mushroom residue.

Functional compost, its preparation methods, and its application in restoring degraded grazing grasslands

This invention discloses a method for preparing functional compost, belonging to the field of agricultural waste resource utilization and grassland ecological restoration technology. The key technical points include: mixing fresh sheep manure, wheat straw, and corn straw at a specific wet weight ratio and adding superphosphate to obtain a basic mixture; inoculating this mixture with a compound microbial fermentation agent composed of *Bacillus steatophilus*, *Bacillus subtilis*, and *Bacillus mucilaginosus* at a specific viable count ratio to obtain an inoculum; subjecting the inoculum to aerobic composting fermentation and implementing dynamic turning control based on dual temperature thresholds to maintain the compost within a specific high-temperature range for a sufficient number of days; and finally, aging the material until its seed germination index reaches a specific range to obtain functional compost. The functional compost prepared by this method is mainly used for restoring degraded grazing grasslands.

Animal waste composting apparatus

ActiveCN224411648UImprove composting efficiencywell mixedMicroorganismAnimal science
The utility model discloses an animal excrement composting device, including composting bucket, composting bucket is cylindrical structure, and the bottom of composting bucket is plane structure and is provided with four supporting legs, and the top of composting bucket is open type interface and is hinged with upper cover plate. The device improves the composting efficiency of animal excrement through the synergies of stirring mechanism, gas injection mechanism and heating plate. The spiral stirring blade ensures uniform mixing of materials, promotes full contact between aerobic microorganisms and excrement, the annular pipe design of the gas injection mechanism uniformly delivers oxygen through multiple exhaust ports, optimizes the aerobic fermentation environment, and the heating plate is attached to the inner wall to provide stable heat, maintain the appropriate fermentation temperature, and shorten the composting period. The temperature sensor monitors in real time and automatically adjusts the operating state of each component through the controller to avoid temperature fluctuations during the fermentation process. This multifunctional integrated design makes the composting process more efficient, especially suitable for small and medium-sized farms to quickly process excrement and produce high-quality organic fertilizer.
