The invention provides a method for acidifying soil conditioner by using a vinasse production facility and application thereof, belonging to the technical field of agricultural solid waste resource utilization and soil remediation, and comprising the steps of mixing vinasse with water, and adjusting the pH value to obtain adjusted vinasse; mixing the adjusted vinasse with acid protease, and stirring and reacting for 22-26 h at 45-50 ℃ to obtain a protease catalytic substance; adjusting the pH value of the protease catalytic substance, mixing the protease catalytic substance with cellulase, and stirring and reacting at 40-45 ℃ for 34-38 hours to obtain a cellulase catalytic substance; filtering the cellulase catalytic substance to obtain a filtrate, mixing the filtrate with magnesium oxide, mixing with a calcium-containing substance, reacting to obtain a reactant, and mixing the reactant with potassium sorbate and sucrose to obtain the facility acidification soil conditioner. The facility acidized soil conditioner prepared by the method provided by the invention not only improves the pH value of the acid soil, but also improves the germination rate of the sowed plants. |
