This invention discloses a high-temperature aerobic fermentation fertilizer made from livestock and poultry manure and straw suitable for saline-alkali land, and its preparation method, relating to the field of mixed fertilizer technology. The apparatus for preparing this high-temperature aerobic fermentation fertilizer made from livestock and poultry manure and straw suitable for saline-alkali land includes a fermentation drum. A feed cover is movably connected inside the fermentation drum, and a discharge cover is movably connected to the outer wall of the fermentation drum. A feed cover is fixedly connected to the right side of the fermentation drum. The method for preparing this high-temperature aerobic fermentation fertilizer made from livestock and poultry manure and straw suitable for saline-alkali land involves rotating the fermentation drum around a fixed axis, turning over the internal pile. An inner convex plate scoops up the bottom pile material and then throws the corresponding pile material downwards, dispersing the bottom pile material onto the top. This allows the pile to maintain a more even temperature during fermentation, resulting in higher microbial activity and significantly improved fermentation efficiency.
