Method for grafting three-line healing of fruit tree

Abstract

The invention belongs to the technical field of fruit tree grafting and discloses a fruit tree three-line healing grafting method which adopts draining water. Cutting ear bud: adopting the method of one bud one joint or two bud one joint to cut the grafting surface under the bud, cutting with one knife, cutting surface is smooth and flat, cutting water surface on the back of the bud, cutting out two cambium lines with wood, cutting surface is smooth and flat; Cutting stock; Grafting. "Y" type water drainage and spring graft are adopted, tree body wound flow is large, if that wound flow cannotbe eliminated in time, cambium is always in a relatively wet environment, and the formation of callus between cambium is hindered, and a saw 2 below the grafting mouth of a large rootstock is used. After cutting the rootstock, the incision was Y-shaped, with a small piece of phloem torn downward in the middle and a small piece of toughness torn downward in the lower end of the rootstock. The effect of water release was very good.

Description

technical field [0001] The invention belongs to the technical field of fruit tree grafting, in particular to a three-line healing grafting method for fruit trees. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: [0003] Fruit tree grafting generally includes spring branch grafting and summer bud grafting. Spring fruit tree grafting uses ungerminated branches for grafting. This method can transport the scion over a long distance and keep it at a certain low temperature and humidity. The scion will not germinate for a long period of time. Grafting takes a long time and can be produced on a large scale. The general grafting includes leaning, splitting, tongue and so on. Budding in summer is difficult to preserve due to the high water content of the scion and the high temperature in summer, so it is required that there must be a picking garden around the nursery. Spring grafting is generally used in the producti...

AI Technical Summary

Problems solved by technology

[0006] (1) Since during the production process, the cambium is only the confluence layer of the phloem and the xylem, which is very thin, it is difficult to align during operation, or it is easy to shift during the binding process, and it is difficult for skilled operators to guarantee it, resulting in Grafting survival rate is low and unstable in production

[0007] (2) In the conventional grafting methods such as docking and cutting, only the cambium on one side of the scion and the rootstock can be aligned, and there are many actual operation errors, and the survival rate is low and unstable

[0008] (3) Although the tongue joint can maintain more shape-layer alignment, the cutting method between the scion and the rootstock is difficult, there are many steps, it is difficult to master, and the operation speed is too slow, so it is not possible to use large-scale promotion

[0010] The difficulty lies in: shortening the time of exposing the cut scion to the air (after a long time, the cut layer is easy to lose water, which is not conducive to the secretion of cambium cells)
