The invention discloses a fertilizer for grapes. The fertilizer for grapes is characterized in that a formula of the fertilizer comprises the following ingredients (by weight): 130 parts of urea, 60 parts of diammonium phosphate, 100 parts of calcium superphosphate, 10 parts of a calcium magnesium phosphate fertilizer, 180 parts of potassium sulphate, 15 parts of borax, 5 parts of copper amino acid chelate, 5 parts of iron amino acid chelate, 5 parts of zinc amino acid chelate, 80-120 parts of grass carbon, 210-280 parts of oil cake, 55-100 parts of humic acid, 20-30 parts of amino acid, 32-48 parts of a biological synergist and 200-300 parts of a bio-organic fertilizer. As the fertilizer for grapes is composed of elements (nitrogen, phosphor, potassium), organic matter, microbes, trace elements, amino acid and a conditioner, soil permeability can be effectively enhanced, soil hardening and acidification can be solved, basic fertility of cultivated lands can be raised, internal nutrients of cultivated lands replace external chemical fertilizer nutrient input, land utilization and land cultivation are combined, and production and income increase of grapes is promoted.
