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;...
