Description

A kind of method of grafting Chinese pagoda tree with golden branch pagoda tree

technical field

The invention relates to plant grafting techniques, in particular to a method for grafting Chinese pagoda tree with golden branch pagoda tree. the

Background technique

Sophora japonica belongs to Papilionaceae arbor plants. Sophora japonica is a good greening tree species, often used as shade tree and street tree, and has certain economic value and medicinal value. It has been used as the local city flower in many areas; Jinzhihuai, also known as Golden Huaihuai and Jinsihuai, is one of the varieties of Chinese Huaihua. Because the branches and leaves are golden yellow throughout the year, it is often used in landscaping and has high ornamental value. Saccharomyces japonica not only has the ornamental value of the four seasons landscape, but also has the effect of improving the stability of the group and forming a good scene when it is mixed with other tree species due to its ecological characteristics. Sophora japonica is grafted on the golden branch of Sophora japonica, but the survival rate is low. the

Contents of the invention

Aiming at the problems existing in the above prior art, the present invention provides a method for grafting Chinese Sophora japonica with golden branch Sophora japonica, thus improving the survival rate

The present invention is achieved through the following technical solutions:

A method for grafting Chinese Sophora japonica Saccharomyces japonica, the method comprises the following steps:

1) Selection of scion during split grafting:

To select scions, it is necessary to select 2-3 years old Chinese pagoda tree in spring, and there are at least 4-5 tooth ears on the scion;

2) Management of scion during chopping:

At 0.8cm below the scion, cut down at 60 degrees and cross-cut to the xylem, and then at about 1.0cm above the scion to be picked, push the knife down from shallow to deep until the incision reaches the xylem, and then the scion can be removed;

3) moisturizing of scion:

Put the bottom of the treated scion into the nutrient water that can promote growth overnight, so that the scion can fully absorb the nutrient water;

4) Management of rootstock during splitting:

Select a 4-5 year-old pagoda tree, cut the anvil at 4m of the trunk of the pagoda tree, remove the branches and leaves on the rootstock, and cut the leaves at a 60-degree downward slope at the lower part of the leaf-picking part to a depth of xylem, and then at 1.5cm above the incision Lower the knife, push the knife down from shallow to deep to the cross incision, deep to the xylem, and remove the middle cut;

5) Split joint:

The bottom of the scion that fully absorbs water in step 1 is put into the incision of step 2, and the incision surface of the bottom of the scion is closely attached to the inboard of the incision of the rootstock, and the outer sides of the upper and lower parts of the joint between the ear and the rootstock are tied tightly with a film. the

Further, the relative humidity of the split joint is 50-55%, and the temperature during the split joint is 20-26 degrees. the

Further, the composition mass ratio of nutrient water is: 70-85% of water, 1-8% of polyacrylamide, 2-8% of phosphate fertilizer, 1-5% of nitrogen fertilizer and 1-8% of potassium fertilizer, trace elements iron, manganese, copper, chromium, Selenium and Zinc 0.5-0.9%. the

The beneficial effects of the present invention are: adopting the method of the present invention, using the Chinese pagoda tree as the scion, and using the Chinese pagoda tree as the rootstock for grafting, while improving the ornamental value, the scion with multi-toothed panicle is selected, and the survival rate is further improved. the

Detailed ways

Example 1

A method for grafting Chinese Sophora japonica Saccharomyces japonica, the method comprises the following steps:

1) Selection of scion during split grafting: the selection of scion needs to be in spring, select 2-3 year old Chinese pagoda tree, and there are at least 4-5 tooth ears on the selected scion; 2) Management of scion during split grafting: under the scion At 0.8cm, cut down at 60 degrees and cross-cut to the xylem, then push the knife down from shallow to deep at about 1.0cm above the fringe to be taken until the incision reaches the xylem, and then the scion can be removed; 3) Moisturizing of the scion : put the bottom of the treated scion into nutrient water that can promote growth overnight, so that the scion can fully absorb the nutrient water; 4) rootstock management during splitting: choose 4-5-year-old Sophora japonica, and carry out at 4m of the trunk of Sophora japonica Cut the anvil, remove the branches and leaves on the rootstock, cut a knife at the lower part of the leaf-picking part with a downward slope of 60 degrees to the xylem, and then lower the knife at 1.5cm above the incision, push the knife down from shallow to deep to the cross-cut, as deep as Xylem, the cut piece in the middle is removed; 5) splicing joint: put the fully water-absorbing scion bottom in step 1 into the incision of step 2, and make the incision surface at the bottom of the scion and the inside of the incision of the stock close to each other, and the ear The outer sides of the top and bottom of the joint with the rootstock are fastened with a film. the

Wherein, the relative humidity of the split joint is 50-55%, and the temperature during the split joint is 20-26 degrees; the composition mass ratio of the nutrient water is: water 70-85%, polyacrylamide 1-8, phosphate fertilizer 2- 8%, nitrogen fertilizer 1-5%, potassium fertilizer 1-8%, trace elements iron, manganese, copper, chromium, selenium and zinc 0.5-0.9%. the

The present invention adopts the method of the present invention, uses the Chinese pagoda tree as the scion, and uses the Chinese pagoda tree as the rootstock to carry out the method of grafting, while improving ornamental value, selects the scion of multi-toothed panicle, further improves the survival rate. the
