Zusammenfassung:The invention discloses a soil conditioner using glucosamine hydrochloride waste liquid and a preparation method and application thereof, and the preparation method comprises the following steps: adding CaO into the glucosamine hydrochloride waste liquid, stirring, pressurizing and heating to obtain slurry and mixed steam; concentrated sulfuric acid is added into the mixed steam, and the concentrated sulfuric acid falls back to slurry; and adding water into the slurry, stirring, naturally settling, and taking supernate to obtain the soil conditioner. The soil conditioner prepared by the invention aims at saline-alkali soil, can reduce the pH value of the soil, and can supplement nutrient elements and active substances beneficial to crops for the soil. 本发明公开了一种利用氨基葡萄糖盐酸盐废液的土壤调理剂及其制备方法和应用,包括以下步骤:向氨基葡萄糖盐酸盐废液中加入CaO,搅拌,加压加热,得到浆体和混合蒸汽;向混合蒸汽中加入浓硫酸,浓硫酸回落至浆体;向浆体中加水搅拌,自然沉降后取其上清液即得土壤调理剂。本发明制备的土壤调理剂针对盐碱化土壤,既能降低土壤pH,又能为土壤补充养分元素及对农作物有益的活性物质。
