Problems solved by technology

[0002] Wenwan walnuts have a very long history. Since ancient times, there have been many varieties of Wenwan walnuts. However, due to excessive picking and poor protection of wild mother trees, many wild walnut trees have been destroyed. It is extinct and can only exist in memory. At present, there are very few wild walnut trees in nature, so the protection of wild walnut trees is particularly important.
[0003] Precious and rare wild walnut trees have very high commercial value. It is very common to use the branches of wild walnut mother trees to graft to increase the output of Wenwan walnut. When damaged, the root system cannot function normally and the healthy growth and development of the wild walnut tree will be affected
If effective technical measures cannot be taken in time to save and rejuvenate, the wild walnut tree may not escape the doom of death
Especially for the rare wild walnut trees, it is very necessary to take scientific and effective protection measures to keep them alive and to continue their unique value, but so far there is no corresponding scientific and effective restoration method

Embodiment 1

[0021] Embodiment one: a kind of wild walnut root grafting method, comprises the following steps:

[0022] S1: Judging the damage of the mother tree. In spring or autumn, the average temperature is 15-20 degrees. Carefully dig the soil at the root of the mother tree. When it is close to the roots of the mother tree, use a brush to remove the soil and tidy up the roots. Cut the heel at the upper 3cm, and use a root cutting spade to cut off the part to be cut. The incision should be cut flat to reduce the wound surface. The root system of the mother tree with good root growth status is used as the grafted child root;

[0023] S2: Selection and transplantation of donor trees. Choose the same tree species as the mother tree or a tree species with good compatibility as the donor tree. The donor tree should choose a healthy tree with good growth and no pests and diseases for 5 years as the donor. The ground diameter of the main tree is 7cm, and one or more donor trees are transplan...

Embodiment 2

[0027] Embodiment two: a kind of wild walnut root grafting method, comprises the following steps:

[0028] S1: Judging the damage of the mother tree. In spring or autumn, the average temperature is 15-20 degrees. Carefully dig the soil at the root of the mother tree. When it is close to the roots of the mother tree, use a brush to remove the soil and tidy up the roots. Cut the heel at the upper 6cm, and use a root cutting spade to cut off the part to be cut. The incision should be a flat cut to reduce the wound surface. The root system of the mother tree with good root growth status is used as the grafted child root;

[0029] S2: Selection and transplantation of donor trees. Choose the same species as the mother tree or a tree species with good compatibility as the donor tree. The donor tree should choose a healthy tree with good growth and no pests and diseases for 15 years as the donor. The ground diameter of the main tree is 15cm, and one or more donor trees are transplant...

Embodiment 3

[0033] Embodiment three: a kind of wild walnut root grafting method comprises the following steps:

[0034] S1: Judging the damage of the mother tree. In spring or autumn, the average temperature is 15-20 degrees. Carefully dig the soil at the root of the mother tree. When it is close to the roots of the mother tree, use a brush to remove the soil and tidy up the roots. Cut the heel at the upper 5cm, and use a root cutting spade to cut off the part to be cut. The incision should be cut flat to reduce the wound surface. The root system of the mother tree with good root growth status is used as the grafted child root;

[0035]S2: Selection and transplantation of donor trees. Choose the same tree species as the mother tree or a tree species with good compatibility as the donor tree. The donor tree should choose a healthy tree with good growth and no pests and diseases for 10 years as the donor. The ground diameter of the main tree is 10cm, and one or more donor trees are transpl...

Abstract

The invention discloses a wild walnut root grafting method which comprises the following steps: S1, judging the injury condition of a seed tree, arranging root hair, and cutting the rotten root hair from the position 3-6 cm above the rotten part; S2, selecting and transplanting a donor tree, and selecting a tree species which is the same as the seed tree or has good affinity as the donor tree; S3, grafting the root system, forming an oblique cut facing the tail end of the root hair on the side surface of the upper end of the root hair of the grafted mother root, forming an oblique cut at the tail end of the grafted child root, and inserting the cut of the grafted child root into the oblique cut of the grafted mother root; S4, carrying out maintenance of root grafting; and S5, carrying out soil backfilling. The method has the advantages that the damaged part of the root system of the wild walnut seed tree is successfully repaired, the vigor of the wild walnut seed tree is recovered during repairing, and the wild walnut seed tree grows more vigorously. By means of the method, in-situ rescue and rejuvenation type restoration of the wild walnut seed tree can be achieved, and the method has obvious scientific research value, ecological benefits, economic benefits and social benefits.
