This invention belongs to the field of soil conditioner technology, and relates to a method for preparing a soil conditioner, the resulting soil conditioner, and its application method. The preparation method includes the following steps: mixing brewing sludge and biogas residue with sorghum straw particles to obtain a mixture; adjusting the carbon-to-nitrogen ratio to 20:1 to 40:1; adding an organic material composting agent; aerobic fermentation at 55℃ for ≥15 days; turning and cooling the pile at temperatures >65℃; and fermenting for 15-30 days after cooling to below 50℃ to obtain the soil conditioner. By utilizing the nitrogen source of the biogas residue to neutralize the high-carbon characteristics of the straw, and further enhancing the synergistic decomposition of the two by the organic material composting agent, this invention promotes rapid aerobic fermentation and stable high-temperature fermentation for over 15 days. This ensures harmlessness while avoiding the high-temperature burning of beneficial bacteria in the composting agent and the disruption of the synergistic decomposition of the biogas residue and straw, achieving complementary advantages between the biogas residue and straw, and producing a loose, breathable, nutrient-balanced, and safely composted soil conditioner.
