The invention discloses a macroelement water-soluble fertilizer containing potassium fulvate. The water-soluble fertilizer is prepared by mixing and grinding the following raw materials, and is prepared by mixing the following components in parts by weight: 30-50 parts of urea, 20-30 parts of potassium nitrate, 10-20 parts of potassium dihydrogen phosphate, 3-7 parts of nitro phosphate, 4-8 partsof ammonium sulfate, 2-4 parts of potassium fulvate, 0.1-0.2 part of compound sodium nitrophenolate, 0.04-0.06 part of sodium naphthalene acetate, 0.3-0.5 part of sodium dodecyl benzene sulfonate, 0.08-0.12 part of a stabilizer, 2-4 parts of boric acid, 0.03-0.05 part of a fertilizer synergist, 3-7 parts of ethylene diamine tetraacetic acid (EDTA) chelated iron, 3-7 parts of EDTA chelated zinc and3-7 parts of EDTA chelated manganese. The preparation method comprises the following steps: putting the raw materials into a stirring device for mixing under a dry production environment according tothe proportions, then carr
