NOVELTY - Method for preparing a foliar fertilizer suitable for tea trees involves (a) first compounding and reducing graphitic carbon nitride and graphene oxide, mixing the potassium permanganate solution, the acetic acid aqueous solution, the potassium chloride aqueous solution, and the graphite phase carbon nitride/graphene composite, transferring to the reaction kettle I, and heating the reaction, (b) adding the graphitic carbon nitride/graphene/manganese dioxide nanowire composites together with ethylene glycol and potassium hydroxide into the reactor II, mixing and stirring evenly, vacuuming, heating, feeding ethylene oxide, polymerization reaction occurs, and obtaining a modified compound, (c) using shrimp waste, banana peel, and spirulina as raw materials, and fermenting, and (d) adding the modified compound to the fermentation broth, dipping, and homogenizing to obtain the product. USE - The method is used for preparing a foliar fertilizer for tea trees. ADVANTAGE - The foliar fertilizer prepared by the method promotes the growth of tea leaves and greatly improves the yield and quality of tea leaves. DETAILED DESCRIPTION - Method for preparing a foliar fertilizer suitable for tea trees involves (a) first compounding and reducing graphitic carbon nitride and graphene oxide to obtain a graphitic carbon nitride/graphene composite, mixing the potassium permanganate solution, the acetic acid aqueous solution, the potassium chloride aqueous solution, and the graphite phase carbon nitride/graphene composite to obtain a premix, transferring to the reaction kettle I, and heating the reaction to obtain the graphite phase carbon nitride/graphene/manganese dioxide nanowire composite, (b) adding the graphitic carbon nitride/graphene/manganese dioxide nanowire composites together with ethylene glycol and potassium hydroxide into the reactor II, mixing and stirring evenly, vacuuming, heating, feeding ethylene oxide, polymerization reaction occurs, and obtaining a modified compound, (c) using shrimp waste, banana peel, and spirulina as raw materials, and fermenting to obtain fermentation liquid, and (d) adding the modified compound to the fermentation broth, dipping, and homogenizing to obtain the product.
