Embodiment Construction

[0010] The invention discloses a method for grafting and cultivating walnut trees by slotting and cutting. The method is to select old walnut trees that have been planted for more than three years and perform grafting in spring. Such as figure 1 As shown, cut off the old walnut tree from the height of trunk 1200mm~1400mm as rootstock 1, cut V-shaped incision 2 at the broken end, and cut 20mm~50mm long along the epidermis on both sides of the trunk at the bottom of the V-shaped incision. Drainage vertical groove 3, makes the tannin juice of old walnut tree flow down along vertical groove 3. Split along the bark at the top of both sides of the V-shaped incision, after inserting the scion 4, wrap the interface tightly with a plastic strip to expose the scion. The scion used for grafting is the branch of the improved variety walnut tree selected, with a length of more than 20mm and at least one bud eye. It is simple and quick to complete the incision, drainage vertical groove, s...

Abstract

The invention relates to a notching and bark insertion grafting cultivation method of walnut trees. The method comprises the steps that trunks of old walnut trees which are planted for three or more years are cut off from the height of 1200-1400 mm, the cut trees are used as stocks, V-shaped notches are cut at the cutting parts, drainage vertical grooves which discharge out tannin juice are downward cut at the bottoms of the V-shaped notches along the bark layers of the two edges of each trunk, the tops of the two edges of each V-shaped notch are split along the corresponding bark, and scionsare inserted in the notches and tightly bound up. The notching and bark insertion grafting cultivation method of the walnut trees is simple and convenient, and the survival rate of the grafted walnuttrees is high.

Description

technical field [0001] The invention belongs to the technical field of walnut tree grafting methods. Background technique [0002] Walnut tree is a kind of important economic crop, and all areas suitable for planting walnut in our country are promoting planting on a large scale. In order to improve the quality of walnuts and increase the yield of walnuts, the industry generally adopts walnut grafting technology. Existing walnut tree grafting method is more, as traditional splitting method, skin grafting budding method, square grafting method, inserting skin tongue grafting method etc. The splitting method is to split a hole on the rootstock, insert the scion and bind it. The skin-grafting budding method is to pry open the bark on one or both sides of the rootstock incision, take a square-shaped scion bud piece, put the scion into the rootstock incision, cover the scion bud piece with the rootstock bark, and then wrap it up. The square grafting method is that the bud sheet...
