The invention discloses a method for in-vitro quick propagation of styrax faberi. The method comprises the following steps of (1) seed germinating; (2) subculture; (3) seedling strengthing and rooting culture; (4) seedling exercising and transplanting. The method for in-vitro quick propagation of the styrax faberi has the advantages that seed husk of the styrax faberi is removed, so that the air ventilating property and water permeating property are improved; endosperm is removed, so that the influence to seeds by germinating inhibiting matters and seed browning causing matters is decreased, a germinating rate and a survival rate are increased, and germinating time is shortened; a hormone type and a concentration ratio of a multiplying culture medium are optimized, so that a multiplying coefficient is increased; a rooting method, a rooting basic culture medium, the hormone type and the concentration ratio are optimized, so that a rooting rate is increased, a rooting number is increased, and rooting time is shortened; the in-vitro culture and quick propagation are realized, and a foundation is laid for the seedling supply of the styrax faberi in the fields of garden greening, edge slope restoration, medicines, greases and the like.
