Compound bio-organic fertilizer for cherries and preparation method of fertilizer

The invention provides a compound bio-organic fertilizer for cherries. The compound bio-organic fertilizer is prepared from, by mass, 25-35 parts of livestock manure, 10-15 parts of plant ash, 15-25 parts of plant enzymes, 15-20 parts of sulphate-potassium magnesium, 10-15 parts of urea iron fertilizer, 10-15 parts of Zinpro, 15-20 parts of fish bone meal, 5-15 parts of edible fungus dregs, 2-8 parts of starter culture for an organic fertilizer, 2-6 parts of DA-6 and 2-8 parts of wood vinegar. The compound bio-organic fertilizer is prepared by compound-mixing farm manure and conventional fertilizer and adding the plant enzymes, the nutrition is sufficient, requirements of the cherries in all growing periods on nutrient substances are met, and the fertilizer efficiency balance of the cherries is promoted; meanwhile, damage of chemical fertilizers to a soil structure can be effectively reduced, and growth of roots of fruit trees and absorption of nutritional components are promoted; cherry trees applied with th
