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.

The utility model relates to the technical field of compost turners, and discloses a rake tooth type straw and cow dung compost turner which comprises a fermentation tank, the upper portion of the fermentation tank is connected with a fixed rail, the upper side of the fixed rail is provided with a moving wheel, the middle of the moving wheel is connected with a connecting shaft, and the curved surfaces of the two ends of the connecting shaft are each rotationally connected with a baffle through a bearing. The tops of the two baffles are fixedly provided with the same supporting plate, the driving structure is rotationally arranged between the two baffles and comprises a turning roller, a spiral blade, rake teeth and a cutter, the turning roller is rotationally arranged at the bottoms of the two baffles, the spiral blade is fixedly arranged on the curved surface of the turning roller, the rake teeth are fixedly arranged on the turning roller, and the cutter is fixedly arranged on the turning roller. The cutters are movably arranged between the turning and throwing roller and the rake teeth, centrifugal force generated when the turning and throwing roller rotates enables the cutters on the two sides to be thrown out to cut straw between the rake teeth, blockage caused by the fact that the straw winds the rake teeth is avoided, and then the composting efficiency is improved.

This invention provides a method and application for preparing bio-organic fertilizer through synergistic composting of biochar-containing biogas residue, belonging to the field of organic fertilizer preparation technology. The method includes: preparing biogas residue through anaerobic fermentation of livestock and poultry manure and crop straw; adding biochar and a compound microbial agent; conducting high-temperature aerobic composting; and obtaining bio-organic fertilizer through maturation and aging. The amount of biochar added is 5%-10% of the dry basis weight of the composting raw materials; the aerobic composting time is 35-45 days; and the high-temperature composting temperature is 55-65℃. The compound microbial agent includes *Bacillus steatophilus*, *Bacillus amyloliquefaciens*, and *Bacillus mucilaginosus*. The bio-organic fertilizer obtained by this invention can be used for crop soil improvement. This invention, through the synergistic effect of biogas residue, biochar, and compound microbial agent, effectively shortens the composting cycle, improves compost maturity, reduces nitrogen loss, passivates heavy metals, and significantly improves the quality of organic fertilizer.

The utility model is suitable for the technical field of treatment equipment, and provides a composting device. The composting device comprises a composting container which is provided with a composting space for accommodating composting materials and can rotate; the cutting piece is arranged in the composting space, can rotate relative to the composting container and is used for cutting the composting materials in the composting space; the spraying piece is arranged in the composting space and is used for spraying liquid into the composting space. The rotating composting container can enable composting materials in the composting space to be continuously turned over and mixed, the rotating cutting piece can cut and crush the composting materials, and under the combined action of the composting container and the cutting piece, the contact area of the composting materials, air and microorganisms can be remarkably increased, so that the composting materials can be effectively decomposed. Therefore, the decomposition effect of microorganisms in the composting process is effectively accelerated, the time consumed by composting is shortened, and the composting efficiency is improved.

The utility model relates to the technical field of fertilizer discloses a compost spraying device, including support leg, the inside sliding joint of support leg has support frame, the inner top of support frame is fixedly connected with the fender, the lateral wall of support frame is opened and is equipped with the adjusting groove, the top of support frame is provided with the water tank, the lateral wall of water tank is connected with the water pipe, the lateral wall fixedly connected with servo motor of support frame, the output fixedly connected with first belt pulley of servo motor, the outer surface of first belt pulley is provided with the mechanism of turning over, in the utility model, through the setting of servo motor, first belt pulley, belt, second belt pulley, turning over frame, spray pipe and spray head, satisfy the effect of turning over and spraying to compost, avoid the top humidity of compost in the process of spraying to reach the standard but the internal humidity is not enough, lead to the situation that the microbial activity drops, compost is difficult to rot, be favorable to the efficiency of compost and the quality of compost product of improvement.

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.
