The invention relates to the technical field of fertilizers, especially to an apple-specific rice husk charcoal base fertilizer. Rice husk charcoal contains 30-35% of carbon. Effective contents of N, P and K are respectively 10%, 1% and 7% of the weight of the rice husk charcoal. The rice husk charcoal can also contain a solid waste which is obtained after furfural is prepared from cottonseed hull, and the weight ratio of the solid waste to the rice husk charcoal is 1:4. A preparation method of the apple-specific rice husk charcoal base fertilizer comprises the following steps: milling; adding a fertilizer containing N, P and K, adding bentonite and a binder, and uniformly mixing; granulating; and screening. By the adoption of the rice husk charcoal base fertilizer, the weight of one hundred leaves of Fuji apple leaves can be significantly increased, contents of chlorophyll b and carotenoid and total chlorophyll in the leaves are increased, and photosynthetic performance of Fuji apple leaves is improved; growth of the annual branch of Fuji apples is controlled, nutrient waste is reduced, and it is beneficial to fruit growth and flower bud differentiation for the coming year; Fuji apple hardness and soluble solid and vitamin C contents are raised, titratable acidity is decreased, and sugar-acid ratio of the fruit is raised; and aroma types of Fuji apple are increased, and local flavor of Fuji apple is improved.
