The invention discloses a method for quickly rooting in the ormosia hosie cuttage process. The method includes the steps of cutting selection, cutting band girdle treatment, seedling culturing matrix matching, seedling culturing bed building, and cuttage temperature preservation management and protection, wherein the cuttage temperature preservation management and protection is achieved through a method that cuttings are cut on the position 2 cm to 3 cm below the cutting band girdle position where callus is formed, the cutting blades and lateral branches are removed totally, three to six sprouts are left, the scissoring openings of the top ends of the cuttings are flushed with one another and are coated with Vaseline, the cutting roots are immersed in rooting power solutions or rooting agents, the matrix is inserted, a small plastic film arch shed is built, a shading net with the shading coefficient ranging from 60% to 75% covers the small plastic film arch shed, the temperature of the matrix is controlled within 23 DEG C to 28 DEG C, and the water content of the matrix is remained within 60% to 70%. Root systems are formed 15 days to 20 days after cuttage, counted from cuttage time, the cycle of seedling culturing is shortened by 35 days to 100 days, counted from band girdle pre-treatment, the cycle of seedling culturing is shortened by 20 days to 80 days, the actual survival rate after cuttage reaches 90%, the cycle of seedling culturing is shortened greatly, and production cost is saved.
