Embodiment 1

[0032] During the end of November to mid-December of the first year, saw the trunk of the 8-year-old Kiwifruit Qinmei to a height of 5 cm from the ground. During the growth of the trunk, when the trunk grows to a height of 85 cm, the trunk is cut. Pick the heart once, and when it grows to the first and middle days of June of the second year, saw the 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 trunk to obtain the rootstock.

[0033] From the strong kiwifruit tree of Hongyang 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. Two plump buds are left at the upper end of each branch section, and the two sides of the lower end of each branch section are cut into a 3cm-long inclined beveled surface, and the beveled surface is smooth, that is, the scion is processed.

[0034] Insert the lower e...

Embodiment 2

[0038] During the end of November to mid-December of the first year, saw the main trunk of the 6-year-old kiwi fruit to a height of 7.5 cm from the ground. During the growth of the main trunk, when the trunk grows to a height of 90 cm, the Pick the heart once, and when it grows to the first and middle days of June 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.

[0039] From the strong kiwifruit tree of Hongyang 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 2 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 beveled surface, and the beveled surface is smooth, that is, the scion is processed.

[0040] Insert the lower end of t...

Embodiment 3

[0044] During the period from the end of November to the middle of December of the first year, the main trunk of the 9-year-old kiwifruit Qinmei was sawed to a height of 10 cm from the ground. During the growth of the main trunk, when the trunk grew to a height of 80 cm, the trunk Pick the heart once, and when it grows to the first and middle days of June of the second year, saw the main trunk to a height of 100 cm from the ground, and cut a 3 cm deep incision in the middle of the top surface of the sawn main trunk to obtain the rootstock.

[0045] From the strong kiwifruit tree of Hongyang 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. Two plump buds are left at the upper end of each branch section, and the two sides of the lower end of each branch section are cut into a 2.5cm-long oblique beveled surface, and the beveled surface is smooth, that is, the scio...

Abstract

The invention discloses a grafting method for a kiwi tree, comprising the following steps: the trunk of a kiwi tree with the tree age more than 5 years is sawn off in the period of the end of November and the middle of December of the first year, the kiwi tree grows to the middle of the second year, the trunk of the kiwi tree is sawn off to reach the height of 100-120 cm, scions from a robust kiwi tree are selected and grafted onto the kiwi tree with the sawn-off trunk, grafting incisions are bandaged, and the grafting is finished. Through the grafting method, the disadvantage that a main stem branch is poor in renewability existing in the grafting of kiwi trees with the tree age more than 5 years is solved, the replacement pace of tree spices is accelerated, the trees are quick in recovering growth vigor, the diseases are less, and the fruiting capacity of cultured branch groups is strong.

Description

technical field [0001] The invention belongs to the technical field of plant grafting, and in particular relates to a method for grafting kiwifruit trees. Background technique [0002] Kiwifruit high-splicing head replacement is the shortest way to update old varieties. At present, the traditional high-splicing method for perennial trees is to select 6 to 10 strong main vines from the main vines of strong trees. Grafting in one direction generally enters the initial fruit stage in the second year after grafting, and enters the full fruit stage in the third year. The loss of income for fruit farmers is small, and it is the most suitable grafting method for variety replacement. However, the traditional high-splicing head replacement technology is not effective on kiwifruit trees over 5 years old. It is mainly reflected in the poor aging and renewal ability of the main vine branches, poor disease resistance, and weak growth, resulting in poor ability to draw new branches, and t...
