The invention discloses a special ecological water flush fertilizer for grapes, and belongs to the technical field of fertilizer preparation. The water flush fertilizer comprises, by weight, 1.5 parts of trichoderma, 1.8 parts of nitrogen-fixing bacteria, 0.9 part of phosphate solubilizing bacteria, 0.5 part of potassium solubilizing bacteria, 1.6 parts of bacillus subtilis, 0.9 part of Bacillus thermophilus, 0.5 part of Aspergillus niger, 0.3 part of photosynthetic bacteria, 485 parts of Chinese medicine residues, 660 parts of plant ash, 28 parts of humic acid, 0.1 part of rare earth, 0.5 part of gibberellin, 20 parts of polypeptide fluids and 25 parts of medium trace elements. The water flush fertilizer contains elements such as nitrogen, phosphorus, potassium, zinc, copper, manganese, boron, molybdenum, rare earth and peptide needed for growth of the grapes and can be rapidly absorbed and used by grape root systems, growth and development of grape trees are promoted, more tips are germinated, branches are thick, chlorophyll content is increased, flower bud differentiation is promoted, and yield is improved by 57% or more.
