The invention discloses oriental cherry fertilizer which is prepared from sheep manure, silkworm feces, wormcast, plant straw, egg shells, tea residues, Chinese honeylocust fruits, pine needle meal, beet roots, oriental cherry flowers, orange peel, urea, fulvic acid potassium, zinc sulfate, ammonium dihydrogen phosphate, calcium sulfate, chitosan, brassinolide, starch, bentonite and EM bacteria liquid. A large amount of organic nutritive matter can be provided by the thoroughly-decomposed feces and the plant straw, and the soil fertility is increased; by means of the filtrate obtained by boiling the tea residues, the Chinese honeylocust fruits, the pine needle meal and the like, the soil environment is improved, the morbidity is lowered, and stress resistance is improved; by adding the starch and the bentonite, the water and nutrient retention property of soil is improved, and the fertilizer has the good slow-release effect; by comprehensively using the chitosan and the brassinolide, the aging of plant tissue is delayed, and the flower output is increased. According to the oriental cherry fertilizer, the growth speed of oriental cherry seedlings is increased, the morbidity is lowered, the soil environment is improved, the flower output in the flower season is increased, the flower season is prolonged by 6-8 days, and the using effect is good.
