Problems solved by technology

[0002] Existing pear tree grafting, especially in areas with heavy wind and sand in the northwest, has the problems of low grafting survival rate, slow growth rate, and weak disease prevention ability. For the survival rate of grafting, there are mostly 2-3 buds on the scion, but because the buds of the scion are mostly opposite, sometimes in order to ensure that one bud is upward during grafting, the other bud will be downward, and the scion will face downward after survival The buds will grow downward, and the new branches are easy to break or grow into deformities, which wastes the nutrients of the tree and slows down the growth rate, and requires later pruning, which is time-consuming and labor-intensive.

Embodiment 1

[0017] In mid-March, choose the vigorously growing 2-year-old Du pear as the rootstock, and choose the full branches of the Korla fragrant pear that bear fruit in the first year as the scion. The grafting is high-level grafting, and the grafting starts at a height of 0.6m above the ground;

[0018] First, cut off the rootstock with a single knife, the cut surface is straight and smooth, and cut a vertical incision with a length of 3-4cm on the cut surface; then cut the scion with a bud, and cut the scion into a wedge at the lower part of the bud 1cm , there are two symmetrical bevels, the bevels are 5cm long, then the scion is inserted into the cut of the rootstock, so that the cambium of the scion is aligned with the cambium of the rootstock, the bevel of the scion is exposed outside 0.4cm, and the buds of the scion are above the branch, And in the leeward direction, wrap the interface with a plastic film of PE material to make it airtight, and graft within 1 hour after the Ko...

Embodiment 2

[0021] Select the vigorously growing 3-year-old Du pear as the rootstock, and the branches with full buds of the fruiting branch in the first year are used as the scion, and grafting is carried out within 2 hours after the branch is cut off;

[0022] Grafting steps: 1. Cut the rootstock: cut off at the smooth and jointless rootstock with one knife, the cut surface is straight and smooth, and cut a vertical incision with a length of 3 cm on the cut surface;

[0023] 2. Cut the scion: cut the scion with one bud, cut the scion into a wedge shape at the lower part of the scion at 0.8cm, with two symmetrical cut surfaces, the length of the cut surface is 4cm

[0024] 3. Insert the scion: insert the scion into the cut of the rootstock so that the cambium of the scion is aligned with the cambium of the rootstock, the cut surface of the scion is exposed 0.2cm outside, the bud of the scion is above the branch, and the leeward direction

[0025] 4. Binding: wrap the interface with plast...

Abstract

The invention provides a grafting method of Korla fragrant pears, and belongs to the field of pear tree grafting. By means of control over rootstocks, scions and the grafting process, the grafting method of the Korla fragrant pears is high in grafting survival rate, strong in disease preventing capacity, fast in growth and free of trimming in later period, and the method mainly comprises the steps of preparing materials, grafting and untying after new shoot extraction.

Description

Technical field: [0001] The grafting method of a Korlace pear in the present invention belongs to the field of plant grafting, especially involving a way to grafted a Korla Xiang pear. Background technique: [0002] The existing pear tree grafting, especially in the area with large wind and sand in the northwest, has the problem of low grafting, slow growth rate, and weak disease prevention and harm.However, because the spikes are mostly in the right raw, sometimes in order to ensure that one bud is up, the other buds will go down, and the buds that the scion will grow down will grow downward.While wasting the nutrition of the tree, the growth rate is slowed down, and it needs to be trimmed later, which is time -consuming and laborious. Invention content: [0003] The purpose of the present invention is to provide a way to grafted a Korlace pear with high grafting rate, strong disease prevention and harmful ability, fast growth, and not being trimmed in the later period. [00...
