Problems solved by technology

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

Embodiment 1

[0009] Embodiment 1 is the arbor seedling of grafting Ulmus chinensis:

[0010] (1) Selection and treatment of rootstocks: Grafting Ulmus sinensis tree seedlings, choose white elm as the rootstock. In mid-March, when the rootstock has not yet germinated and the sap starts to flow, saw off the rootstock at a distance of 2.5m from the ground, and remove the cut stubble. Flatten.

[0011] (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.

[0012] (3) Carry out the grafting operation of Ulmus chinensis: Pry open the cortex of the rootstock section with a knife, face the large cut surface of the scion to the xy...

Embodiment 2

[0014] Embodiment 2 is grafting golden leaf country pagoda tree tree seedling:

[0015] (1) Selection and treatment of rootstocks: Graft the golden-leaved pagoda tree seedlings and choose pagoda tree as the rootstock. At the beginning of April, when the rootstock has not germinated and the sap will start to flow, saw off the rootstock at 2.2m from the ground, and cut the cut hairs. The stubble is flattened.

[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) Carry out the grafting operation of Jinye Guohuai: Use a knife to pry open the cortex of the rootstock section, place the large cu...

Abstract

The invention relates to a seedling grafting method, in particular to a bag-sheathing-free ulmus pumila and sophora japonica grafting sealing method, which is characterized in that after the grafting operation is completed, neutral sealant is adopted and is uniformly coated on the cross section of a stock including the grafting position on the cross section, the coating thickness is 0.5 to 2mm, a gap of the stock and a scion is sealed, and the whole grafting process can be completed after the fully coated neutral sealant is cured. The neutral sealant is short for neutral silicone sealant, and is a common building consumable often used on building material markets. The method has the advantages that the bag sheathing and bag breaking processes are omitted, the bird harm is avoided, the grafting survival rate is improved, and the production cost is reduced.

Description

technical field [0001] The invention relates to a seedling grafting method, in particular to a bagging-free grafting and sealing method for Ulmus chinensis and Huaihua japonica. 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 often fall on the rootstock and the scion in spring, peck the film bag and trample the scion, making the scion loose, thereby reducing the survival rate of grafting. Contents of the invention [0003] The purpose of the present invention is to provide a grafting and sealing method for Ulmus chinensis and Huaihua japonica without bagging. This method saves the process of bagging and...
