Embodiment 1
[0023] A kind of walnut tree grafting method, described method comprises the steps:
[0024] Step 1: Rootstock selection, select seedlings less than two years old or low-yield walnut forests more than seven years old, cut off the bottom part of the rootstock at the same time at the smooth part of the branches. When part of the roots at the bottom of the stock is cut off, 80-90% of the roots at the bottom of the stock are cut off completely, and the cut is wrapped with a film band after cutting.
[0025] Step 2: Collect the scion, select a fine variety of walnut mother tree, select and select annual branches with a length of 6-10 cm, a diameter of 1.0-1.5 cm, and more than two full lateral buds as the scion, and use a professional plastic film for grafting on the walnut scion. Pre-wrapping treatment;
[0026] Step 3: Before grafting, soak the base of the scion with a grafting soaking agent. Within 23-29 days after grafting, when calluses grow out of the grafting interface, use...
Embodiment 2
[0028] A kind of walnut tree grafting method, described method comprises the steps:
[0029] Step 1: Rootstock selection, select seedlings less than two years old or low-yielding walnut forests more than seven years old, cut the lower part of the smooth branches, and cut the roots at the bottom of the rootstock. When treating root cuts at the bottom of the rootstock, 95-98% of the rootstock will be cut. The cut treatment process is to cut obliquely on both sides of the root, and the inclined cuts are set opposite to each other to form a "V" shaped cut. The thickness of the woody layer at the bottom of the "shaped incision is 0.3-0.8cm, and then wrap the incision with a film tape. After the grafted scion survives, cut the wood block corresponding to the "V" incision from the rootstock to fill in the incision , and re-wrap with film tape.
[0030] Step 2: collect the scion, select a good variety walnut mother tree, and select branches with a diameter of 1.0-1.5 cm as the scion;...

Abstract
The invention discloses a walnut tree grafting method, and belongs to the technical field of grafting. The method comprises the steps that a rootstock is selected, a low-yield walnut big tree is selected, and part of roots at the bottom of the rootstock are cut off or cut; and scions are collected. The rootstock is cut, full bud eye improved variety walnut branches are selected as the scions, thewalnut scions are subjected to pre-bundling treatment by a plastic film, the peeled surfaces of the scions are in butt joint with a peel pulling opening of the rootstock during grafting, and the outersides of the scions are wrapped with a peel layer of the opening of the rootstock through the plastic film. According to the grafting method, when the scions are cut, the outside slope contact surfaces of the scions are additionally cut and are combined with the improved pulled peel through cut-grafting, the special grafting film is directly used for pre-binding treatment of the scions when the scions are picked, wax sealing and water retention are not needed, the operation link is simplified, the time and the cost can be saved, upward conveying of water can be reduced through root breaking,and the phenomenon of flushing of grafting openings is reduced; and the mutual contact area of cambium can be increased by additionally cutting the outside slope contact surfaces of the scions, and the healing capacity is enhanced.
Description
technical field [0001] The invention relates to the technical field of grafting, in particular to a method for grafting walnut trees. Background technique [0002] Walnut, also known as walnut, is the general designation of Juglandaceae Juglans, native to Central Asia. Walnuts, almonds, cashews, and hazelnuts are also known as the world-renowned "four major dried fruits". Walnuts are rich in nutrients, containing 15-20 grams of protein per hectogram, more fat, and 10 grams of carbohydrates; Flavin and other multivitamins. It is beneficial to the human body and can strengthen the brain. It is one of the nut foods loved by the common people. Known as "Longevity Son" and "Longevity Fruit". [0003] The medicinal value of walnut is very high. It has the effects of invigorating the stomach, nourishing blood, moistening the lungs, nourishing the mind, and prolonging life. Modern medical research believes that the phospholipids in walnuts have a good health care effect on the...
