Problems solved by technology

[0003] The traditional high-graining method is splitting, which is mostly carried out in spring. Choose 2-4 year old rootstocks or large branches with a diameter of more than 3cm, saw off at a smooth place, flatten the saw edge, and split vertically in the middle of the rootstock or large branches with a knife, with a depth of more than 5cm. , cut a symmetrical slope on each side of the scion, about 5cm long, and then quickly insert the cut surface of the scion into the rootstock or branch opening, align it with the cambium, and then tie the joint tightly with plastic strips. The survival rate of the method is extremely low, resulting in labor-intensive and time-consuming work, and the efficiency of grafting work is not high, so it is not suitable for large-scale promotion and application

Embodiment 1

[0023] The high connection method of the weeping tree of the present embodiment may further comprise the steps:

[0024] S1. Selection and treatment of rootstock: choose a robust weeping tree plant as the rootstock, saw off the trunk and leave no branches, after the rootstock is sawed off, use a sharp knife to level the saw edge, and then draw a knife from the fracture. , as deep as the xylem, insert a wedge-shaped bamboo stick with the same thickness as the scion between the xylem and the phloem of the rootstock saw;

[0025] S2, the selection and processing of scion: cut the branch 10cm of the weeping type tree that grows vigorously and do not have damage by disease and pest as scion, soak scion 5min with treatment agent before high grafting, each scion keeps 2 buds, from the lower bud Use a sharp knife to cut down a 3cm-long bevel on the reverse side of the scion, and then cut a 1cm bevel on the front side, and sharpen the lower end of the scion;

[0026] S3, high grafting...

Embodiment 2

[0030] The high connection method of the weeping tree of the present embodiment may further comprise the steps:

[0031] S1. Selection and treatment of rootstock: choose a robust weeping tree plant as the rootstock, saw off the trunk and leave no branches, after the rootstock is sawed off, use a sharp knife to level the saw edge, and then draw a knife from the fracture. , as deep as the xylem, insert a wedge-shaped bamboo stick with the same thickness as the scion between the xylem and the phloem of the rootstock saw;

[0032] S2, the selection and processing of scion: the branch 15cm that cuts the weeping tree that grows vigorously and does not have damage by disease and pest is used as scion, soaks scion with treatment agent 15min before high grafting, and each scion retains 3 buds, from the lower bud Use a sharp knife to cut down a 4cm-long bevel on the reverse side of the scion, and then cut a 2cm bevel on the front side, and sharpen the lower end of the scion;

Abstract

The invention provides a top-grafting method for weeping trees, and relates to the technical field of tree breeding. The top-grafting method for the weeping trees comprises the following steps of selection and treatment of stocks; selection and treatment of scions; top grafting of the weeping trees; management after top grafting; water and fertilizer management. In the top-grafting method for theweeping trees, the selected scions are soaked with a treatment agent, the anti-bacterial and disease-resistant ability of the scions is improved, the situation that the scions are infected with pathogenic bacteria to result in low surviving rate is prevented, the activity of cambiums is promoted, cell division wound healing is facilitated, the callus growth is accelerated, and moreover, the surviving rate of the top-grafting trees is greatly improved.

Description

technical field [0001] The invention relates to the technical field of tree breeding, in particular to a method for high grafting of weeping trees. Background technique [0002] The high-grafting method is one of the grafting techniques. For weeping trees, the high-grafting method is generally used. The high-grafting of weeping trees is the main measure to improve the ability of trees to survive the winter. In cold regions, the high-grafting of weeping trees can be used. The cold resistance of weeping trees can be improved, and some fine varieties can survive the winter safely in this way. [0003] The traditional high-graining method is splitting, which is mostly carried out in spring. Choose 2-4 year old rootstocks or large branches with a diameter of more than 3cm, saw off at a smooth place, flatten the saw edge, and split vertically in the middle of the rootstock or large branches with a knife, with a depth of more than 5cm. , cut a symmetrical slope on each side of the...
