The invention discloses a double-cut surface high-low level joint grafting technology for Torreya grandis. The joint grafting technology is a new grafting method that the long cut surface of a stock is inwards cut bias from bottom to top to the truncation surface, and moreover, the root of the long cut surface of the stock is vertically cut downwards along the part between bark and xylem to form the short cut of the stock; the long cut surface of a scion and the long cut surface of the stock are grafted in a joint manner; the short cut surface of the scion is inserted into the short cut of the stock, and thus, not only is the conjunction degree of the scion and the stock high, are the scion and the stock high more tightly and is the healing power stronger but also the scion is basically vertical upwards, and crown inclination cannot occur after the scion survives; only branches, a terminal bud and 4-5 leaves of the scion are kept, so that the transpiration of the blades is reduced, and the moisture loss is reduced. According to the joint grafting technology disclosed by the invention, only the terminal bud, which is about 1cm, of the scion is kept, and thus, the distance from the stock to the terminal bud is shortened, the sprouting capability of the terminal bud is enhanced, and the grafting survival rate reaches up to 98 percent. A Torreya grandis grafted plant is upright; the crown does not incline; the grouting capability is strong; the crown can be rapidly formed.
