NOVELTY - Graphene-rare earth compound fertilizer comprises a graphene-rare earth compound and a compound fertilizer. USE - The fertilizer is used for increasing yield, increasing nutrient absorption speed of crops and improving plant stress resistance and used for grain crops, fruits, vegetables, cash crops. ADVANTAGE - The fertilizer reduces the loss of the rare earth elements and improves the utilization rate of the rare earth elements. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation method of the graphene-rare earth compound fertilizer involving (S1) stirring, mixing and crushing 0.1-5 pts. wt. graphene-rare earth compound and 95-99.9 pts. wt. compound fertilizer raw materials to obtain a fertilizer mixture, (S2) granulating the fertilizer mixture in a rotary drum granulator through humidification and heating to obtain granules, and (S3) drying, screening and cooling the granulated substance to obtain the graphene-rare earth compound fertilizer, crushing with rotating speed of 800-1500 rpm, and the particle size of the mixture after crushing is 0.5-5 mm, the rotating speed of the rotary drum granulator is 9-12 rpm, and heating at 60-100℃ and drying at 80-100℃ to obtain the product.
