Embodiment 1

[0023] (1) cut the roots and excavate the roots of American acacia acacia in the same year at the end of March, and store them with mud. From the beginning of April to the first ten days of May, choose the strong ones to clean up, and cut the 10cm long root sections as stock for subsequent use. The upper end of the root needs to keep a 1-2cm long root neck, and the fibrous root should be trimmed to a length of 3cm;

[0024] (2) the opening is cut vertically from the neck to the root on the above-mentioned stock with a knife, forming a kerf of depth 1cm;

[0025] (3) cut the scion and get the Acacia acacia branch, cut the segment with 2-3 full buds as the scion, cut one side of the bottom of the scion into a large inclined plane of 2cm, the same side of the described large inclined plane and the terminal bud, and Cut a small 1cm long noodle on one side;

[0026] (4) binding the above-mentioned cut scion is inserted in the otch of rootstock rapidly by the direction that the lar...

[0033] (4) binding the above-mentioned cut scion is inserted in the otch of rootstock rapidly by the direction that the large cut face is facing outwards and t...

Embodiment 3

[0037] (1) cut the root at the end of March and excavate the root of American acacia acacia in that year, and store it with mud. From the beginning of April to the first ten days of May, choose the strong one to clean up, and cut the long root section of 15cm as stock for subsequent use. The root section The upper end of the root needs to keep a 1-2cm long root neck, and the fibrous root should be trimmed to a length of 3cm;

[0038] (2) the opening is cut vertically from the neck to the root on the above-mentioned stock with a knife, forming a kerf of depth 1cm;

[0039] (3) cut the scion and get the Acacia acacia branch, cut the segment with 2-3 full buds as the scion, cut one side of the bottom of the scion into a large inclined plane of 2cm, the same side of the described large inclined plane and the terminal bud, and Cut a small 1cm long noodle on one side;

[0040] (4) binding the above-mentioned cut scion is inserted in the otch of rootstock rapidly by the direction th...

Abstract

The invention relates to a grafting method of Gleditsia triacaanthos sunburst. The method comprises steps as follows: (1) root pruning; (2) opening forming; (3) scion cutting; (4) binding; (5) wax sealing. The method is used for breeding the Gleditsia triacaanthos sunburst, the production cycle is short, the survival rate is high, the production cost is low, and operation is convenient.

Description

technical field [0001] The invention relates to the technical field of plant breeding, in particular to the field of a method for grafting acacia acacia. Background technique [0002] American acacia, (scientific name: Gleditsia triacaanthos'sunburst'), broad-leaved deciduous tree, plant height 9-10.5 meters, fast growth, no branch thorns, young leaves are golden yellow, mature leaves are light yellow-green, and are still light yellow-green in autumn , the branches are stretched, the plant shape is beautiful, and it is not strong. It is light-loving and slightly shade-tolerant, drought-tolerant, cold-resistant, and can withstand low temperatures of -34 degrees. It likes warm and humid climate and deep fertile soil. It can also grow on calcareous and mild saline-alkali soil. It has wide adaptability and can be planted from northern to southern and southwest China. Deep roots, less pests and diseases. During production, it was found that some plants were harmed by longhorn ...
