Problems solved by technology

[0004] The technical problem to be solved and the technical task proposed by the present invention are aimed at the problem that some landscape tree species have a single crown type, lack aesthetic feeling, and have poor ornamental value; and the in vitro grafting of long branches in conventional grafting is not easy to survive. The scion is grafted on the side branch of the same tree with the branch as the scion; the scion is not separated before grafting, and after the graft survives, it is cut off to separate it and hung on the crown of the rootstock to ensure the survival of the graft. High efficiency, unique shape, can significantly improve the landscape appreciation value of landscape trees

Embodiment 1

[0036] Ginkgo biloba (G.biloba) branches and spikes grafting

[0037] 1. Overview

[0038] There are 5 10-year-old ginkgo landscape trees, each grafted with 5 scions (scions), and a total of 25 shoots.

[0039] 2. Branch spike grafting

[0040] In late March, on the crown of each ginkgo tree, 5 branches were selected as rootstocks, and the 5 adjacent branches of the same plant were scions (branch spikes). Grafting by butt-joint method: the joint of branches and ears is cut from bottom to top, a little xylem is cut off, the front is cut into a horse ear shape with a length of about 2.0cm to 3.0cm, and the upper end of the back is cut into a 0.5cm to 0.8cm long oblique section (see figure 2 ). On the rootstock branch, cut into a longitudinal section with a depth of xylem, corresponding to the branch ear, and a length of about 2.0cm to 3.0cm (see figure 1 ). Then make the scion and the rootstock incision closely connected, and wrap it with a plastic film band without a knot...

Embodiment 2

[0046] Metasequoia (M.glyptostroboides) branches and ears grafted

[0047] 1. Overview

[0048] There are 3 8-year-old metasequoia landscape trees, each grafted with 10 branches and ears, a total of 30 branches and ears.

[0049] 2. Branch spike grafting

[0050] For each Metasequoia tree, 5 branches and spikes are grafted in the middle of the crown and 5 branches and spikes are grafted in the lower part of the crown. Grafting method step is the same as embodiment one.

[0051] 3. Cultivation management

[0052] Same as the general metasequoia tree.

[0053] In the present embodiment, 29 branches and ears were survived altogether, and the survival rate was 96.7%.

Embodiment 3

[0055] Grafting and Propagation of Kuding Tea Tree (I.latifollia)

[0056] 1. Overview

[0057] There are 20 5-year-old saplings of Kudingcha, each grafted with 5 branches and ears, and a total of 100 branches and ears.

[0058] 2. Branch spike grafting

[0059] In the first ten days of April, 15 plants and 75 spikes were grafted on the same plant; 25 spikes were grafted from adjacent different plants. Grafting method step is the same as embodiment one.

[0060]After the grafting survived, in the first ten days of October of that year, the surviving branches and ears were cut off 30 cm below the joint, and the incision should be smooth. Then wrap it with a plastic bag filled with soil (different from layering propagation) to promote callus and new roots from the incision. By the end of October of the following year, cut each surviving fringe hanging under the rootstock branch from the tip close to the joint. It is then planted in a nursery plot to grow into a new plant. ...

Abstract

The invention discloses a graft modeling method of branches and ears of trees. At present, crown shapes of part of landscape tree species are single, the beauty is lacked, and the ornamental quality is poor. The grafting in vitro of long branches in the conventional grafting is not easy to survive. In the invention, the tree branches without separating from a parent body are used as the branches and ears, the tree branches of homologous strain or homologous heterologous strain are used as stocks to graft and model. The branches and ears which are used in the invention is the whole branches of the trees but not a branch section, and the branches and ears in grafting is not separated from the parent body, the scion and the stock belong to the homologous strain or the homologous adjacent strain. The grafting healing is easy, the survival rate can reach 97 percent to 100 percent. The graft modeling of the invention is unique and beautiful, the landscape ornamental value of garden landscape tree species is increased significantly. The invention is beneficial to the breeding of endangered rare tree species which are difficult to breed.

Description

technical field [0001] The present invention relates to a tree grafting modeling method, in particular to a landscape forest where branches that are not separated from the body (mother plant) are grafted on the side branches of trees of the same plant or adjacent trees of the same species, and the branches are cut off after they have survived and healed. The lower part of the ear is a grafting modeling method that separates it from the parent body and hangs it on the side branches of the rootstock. Background technique [0002] Grafting is one of the important means of plant reproduction. As far as woody plants are concerned, grafting is generally a part of the tree's vegetative organs (better genetic quality), such as branches, buds, etc., which are cut off from the body (mother plant) and used as scions. By cutting, the scion is made to correspond to the incision of another plant (rootstock) with a close relationship, and the cambium is joined. After healing and survival...
