The invention discloses a slow-release organic compound fertilizer special for grapes. The slow-release organic compound fertilizer special for grapes is prepared from, by weight, 16-22 parts of an organic matter combined slow-release agent, 4.0-6.5 parts of a silicon fertilizer combined sustained and controlled release preparation, 18-23 parts of urea, 18-22 parts of diammonium phosphate, 26-30 parts of potassium sulfate, 0.5-1.5 parts of ferrous sulfate, 1.0-1.5 parts of magnesium sulfate, 1.0-1.5 parts of zinc sulfate and 1.6-2.0 parts of boric acid. The slow-release organic compound fertilizer has the advantages of being low in cost, high in concentration, complete in nutrition, high in utilization rate and the like, and further has the advantages of being remarkable in yield increasing and quality improving effect and the like; the slow-release organic compound fertilizer can be applied one time after grapes sprout in spring, multiple times of top dressing is not needed, the fertilizing frequency is reduced, and the harm caused by fertilizing to root systems is relieved; meanwhile, nutrition balance in grapes can be coordinated, growth can be promoted, and a remarkable effect is achieved on increasing the yield and improving the quality.
