Apple tree top-grafting variety twig inarching and tree form forming method

Abstract

The invention provides an apple tree top-grafting variety twig inarching and tree form forming method, and belongs to the technical field of fruit tree grafting. According to the apple tree top-grafting variety twig inarching and tree form forming method, a method of performing twig inarching after scion grafting is adopted, so that early grafting is realized, the effective growth time of branchesis prolonged, and early fruiting is realized. Twigs are good in branch deformability, operation is easy, and difficulty is small, so that the working efficiency is greatly improved; the healing length is long, the affinity is good, the healing combination is firm, the growth speed is high, the healing effect is good, the number of healing days is small, and the effective growth time is long; no bamboo pole is needed for supporting, all branches can support one another after inarching, multiple effects and multiple purposes are achieved, and the cost is reduced; and tree body forming is early,early fruiting is achieved, and rapid achievement of economic benefits is facilitated.

Description

technical field [0001] The invention belongs to the technical field of fruit tree grafting, and in particular relates to a method for grafting twigs of high-grafting varieties of apple trees and forming a tree shape. Background technique [0002] Grafting is one of the artificial propagation methods of plants, that is, grafting the branch or bud of one plant to the stem or root of another plant, so that the two parts that are joined together grow into a complete plant. Grafting methods are divided into branch grafting and bud grafting. Grafting is a grafting technique that takes advantage of the ability of plants to heal after injury. Similarly, the artificial propagation of apple trees also adopts this grafting method. The current apple tree grafting method is generally by grafting 2 or more scions on the trunk or main branch of the apple tree. After survival, the surviving branches are grafted to each other , so as to achieve the purpose of changing species or optimizing...

Problems solved by technology

The disadvantages of existing this technology: 1, in the existing grafting technology, the step of grafting needs to be carried out after the branches are lignified in August, thereby reducing the effective growth time of the branches in that year; 2, the grafting method adopts subcutaneous grafting, The branches are hard-branched, and grafting is difficult, and each one requires experienced professionals to operate. The professional requirements are high, the work efficiency is low, the cost is high, and time-consuming; 3. The grafting process requires at least two people to cooperate, and each person averages one day Up to 90 trees can be grafted, which is low in efficiency and high in cost; 4. When grafting, subcutaneous grafting does not damage the xylem, and the healing effect is not good. After healing, the connection is weak and the growth rate is slow; 6. Due to the late grafting time, the growth of the tree body is wasted and the branches are easy to split due to external forces such as wind. The tree body is formed late, and the fruiting time is delayed, which will cause great damage to the orchard income. big impact
