Embodiment Construction

[0011] The invention relates to a skin-grafting and bud grafting method of walnut trees. The method is to select old walnut trees planted for more than two years and implement grafting in spring. Such as figure 1 , figure 2 As shown, the trunk is cut off as a rootstock 1, and a piece of rectangular bark 2 is cut on one or both sides of the rootstock, and then two 20mm-30mm long strips of 20mm to 30mm are cut down on both sides of the bottom surface of each rectangular cutout along the epidermis. Drainage vertical groove 3, the tannin juice of walnut tree is drawn; Get the petiole 4 of walnut leaf as scion, insert a piece of walnut leaf petiole in each rectangular incision, cover the rectangular bark that cuts from incision before, with plastic strip Wrap the bark of the incision and tie it tightly, so that the petiole inserts to expose a gap the size of a rice grain. The method of the present invention can also be as image 3 As shown, the trunk is cut off as a rootstock 1...

Abstract

The invention provides a skin-grafting and bud-grafting method for walnut trees. The method includes the steps that a trunk of an old walnut tree which was planted over two years ago is cut off and serves as a rootstock, and a piece of rectangular or round bark is cut from one side or two sides of the rootstock; two vertical drainage grooves used for leading out tannin are downward cut in the twosides of the bottom surface of each rectangular cut along an epidermal layer or a vertical drainage groove used for leading out tannin is downward cut in the bottom of each round cut along the epidermal layer; petioles of walnut leaves serve as scions and are inserted into the cuts respectively, the rectangular or round bark which was cut off from the cuts before is covered, the bark of the cuts is wrapped and tightly tied up by means of plastic strips, and gaps as large as rice grains are reserved in petiole insertion portions. The method is simple and convenient to use, and the grafted walnut tree is high in survival rate.
