Problems solved by technology

The disadvantage of using this method of grafting is that some birds land on the rootstock and scion in spring, pecking through the film bag and trampling on the scion, making the scion loose and reducing the survival rate of grafting

Embodiment 1

[0008] Embodiment 1 grafting golden leaf country pagoda tree seedling:

[0009] (1) Selection and processing of rootstock: choose Chinese pagoda tree as the rootstock, and when the sap will start to flow before it germinates, cut off the rootstock at 2.5m from the ground, and flatten the stubble;

[0010] (2) Scion treatment: select a well-preserved scion, cut the base into a horse-ear-shaped slope, the cut surface should be smooth, the length of the cut surface should be more than 5cm, and the thickness of the thickest part of the slice should be less than 1 / 2 of the ear thickness, and then cut from the cut surface Slightly shave a knife on both sides of the back, do not expose the xylem, and make it into an arrow shape;

[0011] (3) Grafting operation: Use a knife to pry open the cortex of the rootstock section, place the large slope of the scion towards the xylem, and insert it along the incision of the rootstock. , and then on the rootstock joint, use a 15-20 cm long pl...

Embodiment 2

[0014] Embodiment 2 grafting Ulmus chinensis arbor seedlings:

[0015] (1) Selection and treatment of rootstock: When grafting Ulmus sinensis trees, choose white elm as the rootstock. When the sap will start to flow before the rootstock germinates, saw off the rootstock at a distance of 2.5m from the ground, and flatten the stubble.

[0016] (2) Treatment of scion: select a well-preserved scion, cut the base into a horse ear-shaped slope, the cut surface should be smooth, the length of the cut surface should be 4-5cm, and the thickness of the thickest part of the slice should be less than 1 / 2 of the ear thickness, and then from the Slightly shave a knife on both sides of the back of the beveled surface, do not expose the xylem, and make it into an arrow shape.

[0017] (3) Grafting operation: Use a knife to pry open the cortex of the rootstock section, place the large cut surface of the scion facing the xylem, and insert it vertically into the interface. On the rootstock jo...

Abstract

The invention relates to an improved ulmus pumila and sophora japonica bark insertion grafting method, which is characterized in that after the grafting operation is completed, a thin film bag is not used for sheathing a scion to a stock part, and a plastic thin film with the thickness being 0.02 to 0.06mm is adopted for sealing the grafting position, i.e. the plastic thin film is paved on the cross section of a stock, a combining part of the scion and the stock is bundled from bottom to top, a gap of the stock and the scion is sealed, then, the excessive film falls down and is wound and bundled by plastic ropes, finally, mud is covered on the plastic thin film of the cross section, after the grafting position is heeled, the plastic thin film and the plastic ropes are cut in time by a cutter, and the scion is prevented from being cut by the plastic ropes and the plastic thin film. The method provided by the invention effectively solves the problem of damage on the scion when birds peck water in the bag in spring because of drought, so the grafting survival rate of the ulmus pumila and the sophora japonica is improved, the cost waste is reduced, and the production efficiency is improved.

Description

technical field [0001] The invention relates to an improved grafting method of Chinese golden leaf elm and golden leaf Chinese pagoda japonica cuttings. Background technique [0002] Usually, when the grafting of Ulmus chinensis and Huaihua japonica is carried out, after the scion is inserted into the cortex of the rootstock, cover the scion to the rootstock with a film bag, and then tie it tightly with plastic strips from bottom to top. After the grafted part is healed, remove the film bag in time. . The disadvantage of using this method for grafting is that some birds land on the rootstock and scion in spring, pecking through the film bag and trampling on the scion, making the scion loose and reducing the survival rate of grafting. Contents of the invention [0003] The purpose of the present invention is to provide an improved method for grafting of Ulmus chinensis and Huaihua japonica cuttings, which effectively solves the damage caused to the scion when birds peck th...
