Tree sprout-remaining support-free grafting method

Abstract

The invention discloses a tree sprout-remaining support-free grafting method, which is characterized in that: a green soft bark of a scionwood is bonded with the inside of a strip-shaped surface layer of a parental stock, so callus is easy to produce to join the scionwood and the parental stock; and wooden part of the parental stock bark at two sides of the strip-shaped surface layer is not stripped, more callus can be easily produced to be connected with more callus produced at the left side and the right side of an oblique surface of the scionwood, so compared with other method, trees which are grafted with the method are easier to survive, and the survival rate is generally more than 98 percent. At the same time, since sprout branches are remained to produce the photosynthesis, the bark of the parental stock is free from being rotten, and the growth on the periphery of the grafted place is good. Moreover, since the sprout branches produce the photosynthesis, the growth situation of young sprouts can be controlled, the nutrient supply to the parental stock and especially to the root of the parental stock can be increased, and the general growth of the parental stock after being grafted can be promoted; and a section of tree trunk is remained, so the young sprouts can be bond onto the tree trunk, the windproof effect is very good, support for binding a strut can be avoided, and labor and materials can be saved.

Description

technical field [0001] The invention belongs to the technical field of tree grafting variety exchange, and relates to a grafting method, in particular to a tree grafting method for retaining germination and freeing support. Background technique [0002] The existing grafting technology generally adopts the key points of "alignment cambium" and "lubai" technology, but in practical application, there are many defects, such as grafting is not easy to survive, excessive rootstock wound fluid damages the scion, and conventional bandaging affects healing. Injury tissue formation and other situations will appear in varying degrees, resulting in a low graft survival rate (generally no more than 80%). [0003] In the conventional grafting process, the operation of "alignment cambium" and "lubai" is relatively difficult, and it is difficult for ordinary technicians to learn and master. In addition, plastic strips for wrapping and new shoots need to be reinforced with pillars, which n...

[0003] In the conventional grafting process, the operation of "alignment cambium" and "lubai" is relatively difficult, and it is difficult for ordinary technicians to learn and master

In addition, plastic strips for wrapping and new shoots need to be reinforced by tying pillars, which is not only labor-intensive and materials-intensive, but also supports are easy to shake and not firm
