NOVELTY - Graphene rare earth synergistic organic fertilizer comprises graphene rare earth composite and organic fertilizer. USE - Graphene rare earth synergistic organic fertilizer used for increasing the yield of plant. ADVANTAGE - The graphene rare earth synergistic organic fertilizer can increase production and increase nutrient absorption; it can make beneficial carbon-eating microorganisms and small organisms multiply in the soil, promote the land ecological cycle, and gradually improve the soil condition; the antibacterial effect helps to suppress pests and diseases and harmful bacteria, reducing the use of pesticides, and it can reduce the loss of rare earth elements and improve the utilization rate of rare earth elements. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing of the graphene rare earth synergistic organic fertilizer which involves: (1) mixing graphene rare earth composite and organic fertilizer raw material, stirring and crushing to obtain the fertilizer mixture; (2) granulating the fertilizer mixture in the organic fertilizer granulator, screening the qualified fertilizer with grain diameter of 1-5 mm by primary vibration, sending the unqualified fertilizer to the granulator for secondary granulation to obtain the granulated material; and (3) drying the granules, cooling to obtain the graphene rare earth synergistic organic fertilizer, the crushing speed is 800-1500 r/minutes, the grain diameter after crushing the mixture is 0.5-3 mm, and the drying temperature is 80-80 °C.
