Problems solved by technology

[0010] However, the method of sowing seedlings is adopted, and the grown plants are not cultivated due to large inter-individual variation and mixed male and female plants, which have no cultural significance, and are not used in production; and whether it is cuttings of hard branches or green branches, the survival rate is not high. Problems; at the same time, the grafting operation is more complicated, subject to the restrictions of seasons, environment and time and space, and the healing site is also prone to breakage; the cost of tissue culture is high, the technology is difficult, and it is difficult to harden the tissue cultured seedlings, and the transplanting survives. The rate is low, and there is a certain risk of variation

Embodiment 1

[0047](1) The mother tree of the good-growing Actinidia jujube variety "Fenglu" was used as the experimental plant.

[0048] Cultivate a certain number of green branches in the mother tree of Actinidia jujube that is going to be propagated by layering. When the green branches grow to about 1.5m in the current year, the layering of green branches is prepared. The layering period is 60-70 days after germination.

[0049] (2) The method of layering: start to dig a ditch about 15cm deep under the green branch to be layered, and the length of the ditch is equivalent to the length of the green branch;

[0050] Press the green branches in the ditch, fill the ditch with fine soil, the front end of the new shoot is exposed to the ground by 20-30cm, and tied to the support to ensure its continued growth, and the plant is topped 30-40 days before the leaves to control growth;

[0051] After the plants enter the dormancy period in autumn, the layering branches are cut off from the base an...

Embodiment 2

[0056] (1) The mother tree of the good-growing Actinidia jujube variety "Kuilu" was used as the experimental plant.

[0057] Cultivate a certain amount of green branches in the mother tree of Actinidia jujube that is going to be propagated by layering. When the green branches grow to about 1.8m, prepare for green branch layering. The layering period is 70-80 days after germination.

[0058] (2) The method of layering: dig a ditch about 20cm deep at the base of the green branches to be layered, and press the green branches in the ditch, the length of the ditch is equivalent to the length of the green branches;

[0059] Press green branches into the ditch, fill the ditch with fine soil, expose the front end of the new shoot to the ground by 20-30cm, and tie it to a support to ensure its continued growth, and top off the plant 30-40 days before the leaves to control growth.

Embodiment 3

[0065] (1) The mother tree of the good-growing Actinidia jujube variety "Jialu" was used as the experimental plant.

[0066] Cultivate a certain amount of green branches in the mother tree of Actinidia jujube that is going to be propagated by layering. When the green branches grow to about 2.0m, prepare for green branch layering. The layering period is 65-75 days after germination.

[0067] (2) The method of layering: start digging a ditch about 20 cm deep at the base of the green branch for layering, and the length of the ditch is equivalent to the length of the green branch;

[0068] Press the green branches into the ditch, fill the ditch with fine soil, expose the front end of the new shoot to the ground by 20-30cm, and tie it to a support to ensure its continued growth, and top off the plant 30-40 days before the leaves to control growth.

[0069] After the plants enter the dormancy period in autumn, the green branches are cut off from the base and separated from the mothe...

Abstract

The invention provides a layering single bud seedling breeding method for actinidia arguta green branches. In the method, the actinidia arguta green branches in current year are used for carrying outgreen branch layering breeding, axillary buds are not germinated in current year, the rooting percentage of bud sections can be up to more than 90%, the effect of single bud seedling growth can be reached, the breeding rate is high, the method is easy in management, and labor force is saved.

Description

technical field [0001] The invention relates to the field of seedling propagation, in particular to a method for propagation of kiwifruit with green branches and single buds. Background technique [0002] Soft date kiwi fruit, also known as soft date, has the characteristics of strong resistance, rich nutrition, and unique quality and flavor. It is very popular among consumers and has broad development prospects. It is a precious cold-resistant fruit tree resource in my country. In recent years, due to excessive predatory picking, the wild resources of kiwifruit are on the verge of extinction. In order to save the resources of kiwifruit, all localities are vigorously developing the planting of kiwifruit, and the area of ​​kiwifruit planted is also expanding year by year. The rapid breeding of kiwifruit seedlings is the basis for the development of kiwifruit industry. [0003] At present, the methods for the propagation of kiwifruit seedlings mainly include: [0004] (1) ...
