Embodiment 1

[0020] Embodiment one: the grafting method that the apricot tree survival rate of 8 years old reaches 92%

[0021] During the period from the end of November to mid-December of the first year, saw the trunk of the 8-year-old Golden Sun Apricot tree to a height of 6 cm from the ground. During the growth of the trunk, when the trunk grows to a height of 90 cm, the Pick the heart once, wait until the end of July of the second year, saw the main trunk to a height of 130 cm from the ground, and cut a 3 cm deep incision in the middle of the top surface of the sawed main trunk to obtain the rootstock.

[0022] From the strong apricot tree of the Hongfeng variety, select the mature green branches that were born in the current year as the scion. The diameter of the scion is not greater than the diameter of the rootstock. Leave 3 full buds at the upper end of each branch section, and cut the two sides of the lower end of each branch section into a 3cm-long oblique bevel, and the bevel s...

Embodiment 2

[0026] Embodiment two: the grafting method that the apricot tree survival rate of 6 years old reaches 95%

[0027] During the period from the end of November to the middle of December of the first year, the trunk of the 6-year-old Golden Sun Apricot tree was sawed to a height of 8.5 cm from the ground. During the growth of the trunk, when the trunk grew to a height of 95 cm, the Pick the heart once, wait until the end of July of the second year, saw the main trunk to a height of 120 cm from the ground, and cut a 3 cm deep incision in the middle of the top surface of the sawed main trunk to obtain the rootstock.

[0028] From the strong apricot tree of the Hongfeng variety, choose the mature green branches that were born in the current year as the scion. The diameter of the scion is not greater than the diameter of the rootstock. Leave 3 full buds at the upper end of each branch section, and cut the two sides of the lower end of each branch section into a 3.5cm-long oblique cut...

Embodiment 3

[0032] Embodiment three:: the grafting method that the apricot tree survival rate of 9 years old reaches 97%

[0033] During the period from the end of November to mid-December of the first year, the trunk of the 9-year-old Golden Sun Apricot tree was sawed to a height of 10 cm from the ground. During the growth of the trunk, when the trunk grew to a height of 85 cm, the Pick the heart once, wait until the end of July of the second year, saw the main trunk to a height of 110 cm from the ground, and cut a 3 cm deep incision in the middle of the top surface of the sawed main trunk to obtain the rootstock.

[0034] From the strong apricot tree of the Hongfeng variety, select the mature green branches that were born in the current year as the scion. The diameter of the scion is not greater than the diameter of the rootstock. Leave 3 full buds at the upper end of each branch section, and cut the two sides of the lower end of each branch section into a 2.5cm-long oblique bevel, and ...

Abstract

The invention discloses a grafting method for increasing the survival rate of an apricot tree. The grafting method includes the steps that in the period from the end of October to the middle of December of the first year, a trunk of the golden sun apricot tree with the tree age larger than four years is sawn off, when the apricot tree grows to the middle of the next year, the trunk is sawn to be 110-130 cm high, scions are selected from a healthy and strong Hongfeng apricot tree and grafted, and incisions are bound up to finish grafting. By means of the grafting method, the defect that in the grafting process of the apricot tree with the tree age larger than four years, main stem branches are poor in updating capacity is overcome, the updating pace of the tree body variety is accelerated, a tree body recovers and grows fast, the disease occurrence rate is small, and cultured branch groups have high fruit bearing capacity.

Description

technical field [0001] The invention belongs to the technical field of plant grafting, and in particular relates to a grafting method for improving the survival rate of apricot trees. Background technique [0002] Apricot tree high grafting is the shortest way to update old varieties. At present, the traditional method of high grafting for perennial trees is to select 6 to 10 strong main vines from the main vines of the strong tree. Grafting in different directions generally enters the initial fruit stage in the third year after grafting, and enters the full fruit stage in the fourth year. The loss of income for fruit farmers is small, and it is the most suitable grafting method for variety replacement. Bud grafting Bud grafting is the most widely used grafting method for apricot tree propagation. It has the advantages of economy, firm joint, high survival rate, and easy to make up when it is not alive. The bud grafting of apricot trees can be divided into summer bud graftin...
