Grafting method of Magnolia wufengensis

The invention discloses a grafting method of Magnolia wufengensis. A Magnolia denudate nursery-grown plant is taken as a rootstock, a current-growth branch of the Magnolia wufengensis is taken as a scion, and when the branch has a lignifying tendency in autumn, grafting can be started. The grafting method has the following steps: cutting an angular cut reaching xylem closely at the inner side of a phloem portion, then, performing longitudinal vertical sliding cutting downwards from right above the angular cut to the angular cut so as to cut a flat and smooth long tangent plane and ensure that the exposition position of the long tangent plane is mainly disposed on a cambium layer; performing sliding peeling downwards at the opposite side of a scion axillary bud to form a flat and smooth long-horse-ear-shaped tangent plane, wherein the tangent plane bridges over the diameter of the whole branch, a heart center is seen below the middle of the long-horse-ear-shaped tangent plane, and the axillary bud is sheared at a position 0.8 to 1cm away from the upper portion of the axillary bud; and carrying out scion colligation. According to the grafting method provided by the invention, the grafting butt joint surface is enlarged, the more callus a wound generates, healing can be speeded up, through such a means, the technical difficulty of rapid breeding of the Magnolia denudate is solved, and the technical defect is detected that the survival rate by use of a conventional Magnolia denudate grating method is low.
