Embodiment 1

[0017] The grafting method of the same plant grafting was carried out on the biennial artificial Kudingcha ecological forest.

[0018] A. Selection of grafted plants: in March, plants with normal growth and no damage by diseases and insect pests were used as grafting objects.

[0019] B. Cutting of the rootstock interface: At the place where the trunk height is about 60cm and the diameter is 1cm thick (there are side branches available for grafting growing below), first cut upwards an oblique incision at an angle of 30° to the trunk and a depth of about 0.6cm, and then cut it upwards. A longitudinal incision was cut upward at 2 cm below, reaching as deep as the xylem.

[0020] C. Scion incision cutting: Cut the inside of the tip of the selected side branch under the rootstock into a 1.7cm oblique cut, and cut a 0.5cm incision on the back. The two incisions are wedge-shaped and must match the size and height of the rootstock incision. adapt.

[0021] D. Grafting and binding: ...

Embodiment 2

[0025] The three-year-old Kudingcha landscape trees were grafted on the same plant.

[0026] A. Select grafting plants: Select suitable plants as grafting objects in September.

[0027] B. rootstock and scion otch cutting: grafting height is at the high 80~100cm place of trunk, and cutting method is the same as embodiment one.

[0028] C. Grafting and binding: same as embodiment one.

[0029] D. Cultivation management: Remove the sprouts on the scion in time to promote the growth of the rootstock trunk. Remove the binding objects on the interface until May of the following year. Other management measures are the same as general grafted seedlings.

[0030] The grafting survival rate of the present embodiment is 99%, and the high growth amount in the next year is 34% higher than that of the control.

Abstract

The invention discloses a homophyletic scion grafting method. The homophyletic scion grafting method is characterized by comprising the following steps: selecting a plant growing normally and free of diseases and pests as a grafted object, selecting the trunk thereof as a rootstock, and selecting a lateral branch growing strongly on the upper part of the crown thereof as a scion; cutting into a slope opposite to the trunk at an appropriate position of the tip of the lateral branch, and cutting into a longitudinal section on the back surface; upwardly and reversely cutting an oblique incision facing to the longitudinal section of the lateral branch on the trunk above the lateral branch selected as the scion, and then downwardly and longitudinally cutting a longitudinal incision as deep as a xylem from the oblique incision; inserting the longitudinal section of the scion into the longitudinal incision of the rootstock so as to tightly connect the scion and the rootstock; tying and cultivating. By the homophyletic scion grafting method, the grafting time is long, the grafting survival rate is high, and the annual growth amount of a grafted plant is increased by 25-43%; the homophyletic scion grafting method is applicable to many grafted tree species with a large age range, and generally, young and middle-aged plants can be grafted.

Description

technical field [0001] The invention relates to a grafting method for grafting branches of trees (or fruit trees) on the same plant to promote the growth of the plant. Background technique [0002] There are many grafting methods and types of woody plants. According to the height of the grafting part, there are two types: high grafting and low grafting; according to the nature of the scion, it can be divided into branch grafting and bud grafting; among them, the grafting method based on branch grafting includes cut grafting, split grafting, abdominal grafting and butt grafting. And plug skin connection and other methods. Contents of the invention [0003] The technical problem to be solved and the technical task proposed by the present invention are to overcome the shortcomings of existing grafting methods such as short implementation time, low survival rate, and slow annual growth of grafted plants, and provide a grafting method for same-plant grafting. For this reason,...
