Chestnut tree grafting method

A technology of chestnut trees and chestnuts, which is applied in the field of plant cultivation, can solve the problems that the tree body is easy to grow wildly, the new shoots are easy to be broken by the wind, and the efficiency is low, so as to solve the problem of tree body growth, improve tree body illumination, and save grafting The effect of labor

Problems solved by technology

[0009] (1) Low grafting efficiency: For example, if the belly of a big tree is grafted, it needs to be wound many times near the grafting interface to form a pimple; after the branches survive, they need to be removed in time, which is time-consuming and labor-intensive
[0010] (2) New shoots need to be bound: new shoots are easily broken by the wind and need to be bound continuously; when binding, a bracket needs to be erected, which is very inefficient
[0011] (3) The tree body is prone to crazy growth: after grafting, it can often grow into 1-2m long branches. If these long branches are not treated in time, it is difficult to bear fruit
[0013] (5) Long branches need to be pulled: if the heart was not topped in time in the previous year, then in the spring of the second year of grafting, the branches of 1m to 2m will be pulled, which is very labor-intensive and time-consuming
[0015] It can be seen that the traditional grafting method is time-consuming and labor-intensive, and the efficiency is low, and the second year after grafting is often not rich.

Embodiment 1

[0056] 1. Rootstock selection:

[0057] Choose robust growth, more than 5cm in thickness, about 3m in height (the thickness at 2m needs to be more than 3cm in thickness), good grafting compatibility, and disease-free chestnut plants as rootstocks.

[0058] 2. Scion selection:

[0059] Select annual chestnut branches with good quality, high yield, about 30 cm in length and 0.5 cm to 1.0 cm in thickness as scions.

[0060] 3. Rootstock treatment:

[0061] Choose the straightest and thickest branch as the trunk, and choose to leave the trunk more than 2m; use a quick saw or scissors to thin out all the remaining branches.

[0062] Treated rootstocks such as figure 1 shown.

[0063] 4. Scion cutting:

[0064] Use a grafting knife to cut the chestnut scion into a horse-ear shape with a cut surface of 8cm to 10cm in length, cut one knife on the back and two sides each, and cut it into a slanted tip.

[0065] 5. Rootstock cutting:

[0066] Make a horizontal cut on the smooth p...

[0081] 2. Scion selection:

[0082] Select annual chestnut branches with good quality, high yield, 25 cm in length and 0.5 cm to 1.0 cm in thickness as scions.

[0083] 3. Rootstock treatment:

[0084] Choose the straightest and thickest branch as the trunk, and choose to leave the trunk more than 3m; use a quick saw or scissors to thin out all the remaining branches.

[0085] 4. Scion cutting:

[0086] Use a grafting knife to cut the chestnut scion into a horse-ear shape with a cut surface of 8cm to 10cm in length, cut one knife on the back and two sides each, and cut it into a slanted tip.

[0087] 5. Rootstock cutting:

[0088] Make a horizontal cut on the smooth part of the rootstock, reaching to the xylem; at the lower end of the cross cu...

Embodiment 3

[0100] 1. Rootstock selection:

[0101] Choose robust growth, more than 7cm in thickness, about 4m in height (the thickness at 2.5m must be more than 3cm), good grafting compatibility, and disease-free chestnut plants as rootstocks.

[0102] 2. Scion selection:

[0103] Select annual chestnut branches with good quality, high yield, 25 cm in length and 0.5 cm to 1.0 cm in thickness as scions.

[0104] 3. Rootstock treatment:

[0105] Choose the straightest and thickest branch as the trunk, and choose to leave the trunk more than 2.5m; use a quick saw or scissors to thin out all the remaining branches.

[0106] 4. Scion cutting:

Abstract

The invention provides a chestnut tree grafting method which mainly comprises the following steps: a chestnut branch is taken as a scion, the scion is in side grafting with a rootstock, the rootstock side grafting notch is in an inverted triangle shape, the bottom edge of the inverted triangle shape extends upwards to form a longitudinal cutting seam, and the scion is inverted into the cutting seam. According to the grafting method, management procedures such as pinching, branch drawing and sprout carving are saved, the problem that the tree is easy to grow vigorously is solved, the branching angle is expanded, the tree light is improved, and the method is favorable for rapid fruiting.

Description

technical field [0001] The invention relates to the technical field of plant cultivation, in particular to a method for grafting chestnut trees. Background technique [0002] The rich unsaturated fatty acids and vitamins contained in chestnuts can prevent and treat diseases such as hypertension, coronary heart disease and arteriosclerosis. There are also extremely high sugar, fat, protein, calcium, phosphorus, iron, potassium and other minerals, as well as vitamin C, B1, B2, etc., which are useful for strengthening the body. Chestnut has the effects of invigorating the spleen and stomach, nourishing qi, nourishing the kidney, strengthening the waist, strengthening the tendons, stopping bleeding, reducing swelling and strengthening the heart. It is suitable for soreness and weakness of the waist and knees, adverse waist and legs, increased urination, and chronic diarrhea and trauma caused by deficiency of the spleen and stomach. Fractures, blood stasis, swelling and pain, mu...
