Grafting method for kiwi berry tree

Abstract

Provided is a grafting method for kiwi berry trees. The method comprises: beveling from 1 cm below a scion bud eye in an angle of 45 DEG, beveling to 2 / 5 of the diameter of a scion branch, beveling downward from 1 cm above a bud to the depth of the first cut, taking down a bud sheet which slightly has a xylem and is totally 2-3 cm in length, then on a smooth position of a stock, 80 cm-100 cm above the ground, cutting apart the stock according to the method for cutting the bud sheet, and taking down cut blocks; then, embedding the bud sheet in the stock, the scion bud should be aligned at a cambium on one side of the stock, and finally, using a plastic strip to wrap tightly a grafting wound, to prevent moisture from losing. Since seedlings are high in survival rate, the survival rate of kiwi berries grafted by the method is more than 95%. The method greatly improves disease resistance, accelerates growth speed, improves yield, and changing variety is more convenient, just a top grafting position needs changing, and a whole plant does not need to be changed. When grafting in high places, planting and manual operation are more convenient.

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...

Problems solved by technology

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 the resulting position moves outward.
