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] Embodiment 1 is a specific process when grafting Ulmus chinenseensis by the method of the present invention:

[0020] 1. Select rootstock and the treatment of rootstock: when grafting tree seedlings, choose white elm as the rootstock, saw off the rootstock at 2.5m from the ground (determine the height according to the needs of the project), and flatten the cut stubble;

[0021] 2. Handling the scion: select a well-preserved scion, cut the base into a horse-ear-shaped slope, the cut surface should be smooth, the length of the cut surface should be more than 5cm, and the thickness of the thickest part of the slice should be less than 1 / 2 of the ear thickness, and then cut from the cut surface. Slightly shave a knife on both sides of the back, do not expose the xylem, and make it into an arrow shape;

[0022] 3. Grafting: Use a knife to pry open the cortex of the rootstock, place the large scion facing the xylem, and insert it vertically into the interface. The bag is cov...

Embodiment 2

[0024] Embodiment 2 For adopting the inventive method, a specific process when grafting golden leaf Chinese pagoda tree:

[0025] 1, select rootstock and the processing of rootstock: when grafting arbor seedlings, select the original species of common Chinese pagoda tree as rootstock, saw off the rootstock at 2.5m from the ground (determine the height according to the needs of the project), and flatten the stubble of the cutting edge;

[0026] 2. Handling the scion: select a well-preserved scion, cut the base into a horse-ear-shaped slope, the cut surface should be smooth, the length of the cut surface should be more than 5cm, and the thickness of the thickest part of the slice should be less than 1 / 2 of the ear thickness, and then cut from the cut surface. Slightly shave a knife on both sides of the back, do not expose the xylem, and make it into an arrow shape;

[0027] 3. Grafting: Use a knife to pry open the cortex of the rootstock, place the large scion facing the xylem, ...

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 invention relates to a new grafting method of Chinese pagoda japonica and Ulmus chinensis, especially a method for grafting branches of Chinese pagoda japonica and Ulmus chinensis without untying for seedling breeding. Background technique [0002] Grafting is one of the methods of artificial vegetative propagation of plants. That is to graft the branches or buds of one plant onto the stem or root of another plant, so that the two parts connected together grow into a complete plant. Grafting is carried out by utilizing the ability of plants to heal after injury. During grafting, the cambiums of the two injured surfaces are brought close together and tightly bound together. As a result, due to cell proliferation, they heal each other and become a whole connected by vascular tissues. It can be divided into: ① grafting according to the materials obtained from the scion. It is mainly carried out during the dormant period, and it is the most suitable...
