Preparation method and application method of grape special fertilizer

Abstract

The invention relates to preparation method and application method of a grape special fertilizer, wherein the preparation method comprises the following steps: preparing an I-type fertilizer by taking the following ingredients in parts by weight: 30-40 parts of urea, 20-30 parts ammonium phosphate, 15-30 parts of potassium sulphate, 1-3 parts of humic acid, 1-3 parts of excrement, 1-5 parts of synergist, 0.1-1.0 part of ferrous sulphate, 0.1-0.8 part of zinc sulfate, 0.1-0.6 part of manganese sulphate, 0.1-0.6 part of borax, 0.1-0.4 part of copper sulfate, 3-7 parts of plaster and 3-13 parts of bentonite; preparing an II-type fertilizer by taking the following ingredients in parts by weight: 7-15 parts of urea, 25-35 parts ammonium phosphate, 35-45 parts of potassium sulphate, 1-3 parts of humic acid, 1-5 parts of excrement, 2-5 parts of synergist, 0.1-1.0 part of ferrous sulphate, 0.1-0.8 part of zinc sulfate, 0.1-0.6 part of manganese sulphate, 0.1-0.6 part of borax, 0.1-0.4 part of copper sulfate, 3-7 parts of plaster and 3-13 parts of bentonite; and blending, spraying, pelleting and drying at lower temperature to obtain the product. The application method of the fertilizer comprises the following steps: taking an organic fertilizer and the II-type fertilizer as a base fertilizer; applying the I-type fertilizer before blossom, applying the II-type fertilizer in the young fruit development period, and meanwhile, respectively spraying monopotassium phosphate and rare earth mixed liquid once on the leaf surfaces; and spraying calcium nitrate or calcium acetate to enhance the storage resistance property before picking.
