▎ 摘　　要

NOVELTY - Carbon-based mica fertilizer comprises carbon-based two-dimensional nano-materials and mica powder. The carbon-based two-dimensional nanomaterial is one or a combination of two or more selected from graphene, nanographite, graphene oxide, and reduced graphene oxide. USE - Carbon-based mica fertilizer used for agricultural soil (claimed). ADVANTAGE - The carbon-based mica fertilizer is easy to dissociate, absorb and utilizes potassium ions by plants on the surface, and has a synergistic effect in promoting the absorption of nutrients by plant. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing carbon-based mica fertilizer, which involves: (A) mixing carbon-based two-dimensional nanomaterials, mica and water, and rolling to obtain a mixed slurry; (B) crushing hydraulically the obtained mixed slurry; and (C) sieving, settling and drying the solid-liquid separation and the solid materials to obtain a finished product of carbon-based mica fertilizer.
