Embodiment 1
[0023] A walnut tree grafting method, the method comprises the steps:
[0024] Step 1: Rootstock selection, select seedlings less than two years old or low-yielding walnut forests more than seven years old, and base the bottom part on the smooth branch, and at the same time cut off the bottom part of the rootstock. When the bottom part of the rootstock is cut off, completely cut off 80-90% of the root at the bottom of the rootstock, and wrap the cut opening with a film tape after cutting.
[0025] Step 2: Collect scions, select a good 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 two or more plump lateral buds as scions, and grafting professional plastic film on the walnut scion. pre-packaging;
[0026] Step 3: Before grafting, use grafting soaking agent to soak the base of the scion. When you see callus growing out of the grafting port within 23-29 days after grafting, use a new suture-promoting agent...

[0028] A walnut tree grafting method, the 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, and place the bottom part of the branch where the branches are smooth, and at the same time cut the bottom part of the rootstock. When the root of the bottom part of the rootstock is cut, 95-98% of the rootstock is cut. The process of cutting is as follows: on both sides of the root, both sides are inclined to cut, and the inclined incisions are set relative to each other to form a "V" type incision, "V" type incision. The thickness of the wood layer at the bottom of the "V"-shaped incision is 0.3-0.8cm, and then the incision is wrapped with a film tape. After the grafted scion survives, the wood block corresponding to the "V"-shaped incision is cut from the rootstock and filled in the incision. , and wrap it again with film tape.

Abstract
The invention discloses a walnut tree grafting method, belonging to the technical field of grafting. The method includes rootstock selection, selecting a low-yielding walnut tree, cutting off or cutting the bottom part of the rootstock, and collecting scions. The rootstock is peeled and processed, the walnut branches with full buds are selected to be the scion, and the walnut scion is pre-banded with a plastic film, and the peeling side of the scion is docked with the peeling port of the rootstock during grafting, and the cortex of the rootstock opening is wrapped with a plastic film. on the outside of the scion. In this grafting method, when cutting the scion, the external slope contact surface of the scion is increased and the improved peeling is combined. When the scion is harvested, the scion is directly pre-wrapped with a special grafting film. It can save time and cost. By cutting off the roots, it can reduce the upward transport of water and reduce the phenomenon of "flushing" of the grafting interface; by increasing the contact surface of the outer slope of the scion, the contact area of the cambium can be increased and the healing ability can be enhanced.
Description
technical field [0001] The invention relates to the technical field of grafting, in particular to a method for grafting a walnut tree. Background technique [0002] Walnut, also known as walnut, is the collective name for the Jugaceae family of plants, native to Central Asia. Walnuts, together with almonds, cashews, and hazelnuts, are known as the world-famous "four dried fruits". Walnut kernels are rich in nutrients, containing 15-20 grams of protein per 100 grams, more fat, and 10 grams of carbohydrates; and contain essential calcium, phosphorus, iron and other trace elements and minerals, as well as carotene, nuclear flavin and other vitamins. Beneficial to the human body, can strengthen the brain. It is one of the most popular nut foods. Known as "long live" and "longevity fruit". [0003] The medicinal value of walnut is very high. It has the functions of strengthening the stomach, nourishing blood, moistening the lungs, nourishing the mind, and prolonging life. It...
