NOVELTY - A method for preparing soil conditioner using graphene comprises (S1) mixing a composite microbial inoculum with organic matter to obtain a mixture (A), granulating the mixture (A) and heat treating to obtain the core of soil conditioner, (S2) mixing the graphene oxide composite material with expanded vermiculite powder and plant waste fertilizer to obtain a mixture (B), spraying the mixture (B) on the surface of the core and heat treating to obtain the soil conditioner covered by the graphene oxide composite layer and (S3) preparing organic acid salt solution, mixing with graphene oxide composite material and organic matter to obtain a mixture (C), spraying the mixture (C) on the surface of the soil conditioner covered by the graphene composite layer and heat treating to obtain the soil conditioner covered by the organic acid salt composite layer. USE - The method for preparing soil conditioner using graphene. ADVANTAGE - The soil conditioner prepared by the method is mainly aimed at the soil with high water content or large volume and solves the problems that the heavy metal adsorption effect and the microbial proliferation effect of the traditional conditioner are reduced in such soil.
