Problems solved by technology

Use white plastic strips with a width of 3 cm and a length of 30 to 40 cm to tie the joint tightly, because water droplets are easy to form inside the plastic film. After the birds find the water droplets, they often peck through the plastic film to drink water, which will cause the scion to lose water and graft failure.

Embodiment Construction

[0040] The present invention will be further described below in conjunction with the accompanying drawings and embodiments, but the embodiments do not constitute any limitation to the present invention.

[0041] A kind of high chestnut tree grafting method is carried out according to the following steps:

[0042] (1) Scion collection and storage.

[0043] The collection of scions is generally carried out with pruning, and the full, robust, and disease-free 1-year-old branches on the trees of fine varieties are collected as scions. Every hundred scions are tied into a bundle, and the variety is indicated. There are many storage methods. One is to store in plastic bags after being sealed with wax: the scion is quickly sacrificed in paraffin wax at 100-130°C, put into plastic bags and stored in a low-temperature cellar. The second is that it can be directly stored in the cellar: the temperature in the cellar is lower than 5°C, and the lower part of the scion is buried with wet s...

Abstract

The invention relates to a Chinese chestnut big-tree top-grafting method and belongs to the technical field of wood fruit tree farming. According to the method, a big branch is reserved at the top of a tree body during cleaning, residual big branches are short-pruned, movable supporting columns are reserved at the front ends, and the tree bark at the movable supporting columns are peeled off; unions are sealed and are bound by using black plastic strips or a neutral plastic sealing adhesive; movable supporting columns left on the tree body are used for binding new shoots; after grafting and survival, the big branch reserved at the top is removed, or after the reserved branch bears fruits, the branch is removed in winter pruning. The grafting survival rate can be improved, vigorous growth of new shoots is avoided, and films can be prevented from being damaged due to pipping of birds. The unions are sealed by using the plastic sealing adhesive, the working efficiency is greatly improved, and meanwhile a later unbinding process is omitted. Therefore, labor and time are saved. Additional supporting rod binding is not needed during new shoot binding.

Description

technical field [0001] The invention relates to a method for high grafting of large chestnut trees, which belongs to the technical field of forestry and fruit tree cultivation. Background technique [0002] The high-level grafting of chestnut trees is mostly carried out in spring, and the method of abdominal grafting is adopted. The traditional method of high-level chestnut tree grafting is to cut all the large branches to the joints, and it is necessary to tie the sticks later. Use a white plastic strip with a width of 3 cm and a length of 30 to 40 cm to tie the joint tightly, because water droplets are easily produced inside the plastic film. After the birds find the water droplets, they often peck the plastic film to drink water, which will cause the scion to lose water and graft failure. For those tied with plastic strips, it is necessary to untie them later, otherwise the new shoots will be "stuck" and broken. Contents of the invention [0003] The purpose of the pr...
