Problems solved by technology

[0003] The traditional grafting method needs to remove the plastic film after the grafting site is healed; in the management process, in order to prevent the grafting site from being split by the wind, it is necessary to fix the new branch with a bracket, which is time-consuming and laborious, and the effect is not ideal

Embodiment 1

[0019] Example 1 is a specific process when grafting Ulmus sinensis using the method of the present invention:

[0020] 1. Select rootstock and rootstock treatment: When grafting tree seedlings, choose white elm as the rootstock, cut off the rootstock 2.5m from the ground (fix the height according to the project needs), and smooth the cutting stubble;

[0021] 2. Treatment of scion: select the well-preserved scion, cut the base into a horse-ear-shaped bevel. The cut surface should be smooth, and the cut surface should be more than 5cm long. The thickness of the thickest part of the chip should be less than 1 / 2 of the ear thickness, and then cut the surface Cut lightly on both sides of the back, do not expose the xylem, make it into an arrow shape;

[0022] 3. Grafting: Use a knife to pry open the cortex of the rootstock, and insert the scion into the interface vertically with the large cut surface facing the xylem. The depth should be so that the cut surface of the scion is slightly ...

Embodiment 2

[0024] Example 2 is a specific process when using the method of the present invention to graft the golden leaf locust tree:

[0025] 1. Select rootstock and rootstock treatment: When grafting tree seedlings, choose the original species of common Chinese Sophora tree as the rootstock, and cut the rootstock 2.5m from the ground (the height is determined according to the engineering needs), and the cutting stubble is flattened;

[0026] 2. Treatment of scion: select the well-preserved scion, cut the base into a horse ear-shaped bevel, the cut surface should be smooth, and the cut surface should be more than 5cm long. The thickness of the thickest part of the chip should be less than 1 / 2 of the thickness of the ear, and then cut the surface. Cut lightly on both sides of the back, do not expose the xylem, make it into an arrow shape;

[0027] 3. Grafting: Use a knife to pry open the cortex of the rootstock, and insert the scion into the interface vertically with the large cut surface faci...

Abstract

The invention relates to a new grafting method of golden leaf Chinese scholar trees and Ulmus pumila cv.jinye, in particular to an unbinding-free bark and scion grafting method of the golden leaf Chinese scholar trees and the Ulmus pumila cv.jinye for breeding seedlings with the unbinding-free purpose. The method is characterized in that: firstly, a long acting agricultural anti-drop film with the thickness of 0.08cm is employed at a grafting position while grafting for binding and fixing; secondly, the position of the long acting agricultural anti-drop film with the thickness of 0.08cm is fixed at a position which is 1.5-2.5cm higher than the top of a rootstock; and thirdly, the binding film does not need to be unbound. In the method, a support is not needed for fixing and unbinding is unnecessary, which reduces support expense and artificial unbinding cost; the seedlings have natural and perfect healed grafting cuts by employing the unbinding-free technology and have no obvious stubble. The wind resistance and the wormeaten resistance are enhanced.

Description

Technical field [0001] The present invention relates to a new method for grafting golden leaf locust and Chinese golden leaf elm, in particular to the golden leaf locust and Chinese golden leaf elm unbinding grafting grafting method for seedling breeding that can achieve the purpose of unbinding. Background technique [0002] Grafting is one of the artificial vegetative propagation methods of plants. That is, the branches or buds of one plant are grafted onto the stems or roots of another plant, so that the two parts that are joined together grow into a complete plant. Grafting is carried out by taking advantage of the healing function of plants after injury. When grafting, the cambium of the two wound surfaces are brought close and tied together. As a result, due to cell proliferation, they heal each other and become a whole connected vascular tissue. According to the material taken from the scion, it can be divided into: ①Branch grafting. It is mainly carried out during the ...
