Plant grafting method adopting reverse grafting of scion and root stock

Abstract

The invention relates to a plant grafting method adopting reverse grafting of a scion and a root stock. The plant grafting method is characterized by comprising the following steps of reserving a root stock coppice shoot good in growth on a plant which survives after grafting is completed by a conventional grafting method, then respectively cutting seams in the coppice shoot of the plant and the scion, enabling the seam of the coppice shoot to be aligned with and tightly attached to the seam of the scion so that the coppice shoot is grafted to the scion, and tying the coppice shoot and the scion which are grafted for cultivation. The grafting method is particularly suitable for high position grafting and grafting of tree species which are slow in growth vigor and poor in seam healing properties. According to the plant grafting method disclosed by the invention, the coppice shoot of the root stock can be utilized for promoting the growth of the scion, and the situations that the seam of the root stock dies and further the survival of the scion is influenced due to coppice shoot elimination can be avoided; and besides, the new plant of the scion can also grow firmly on the root stock, and wind and snow harm is reduced and avoided.

Description

technical field [0001] The present invention relates to the grafting method of woody plants, especially a kind of method of grafting the shoots of rootstock on the scion, so as to improve the survival and preservation rate of grafting and promote the grafting method of growth. Background technique [0002] There are many grafting methods and types of woody plants. According to the height of the grafting part, there are two types: high grafting and low grafting; according to the nature of the scion, it can be divided into branch grafting and bud grafting; among them, the grafting method based on branch grafting includes cut grafting, split grafting, abdominal grafting and butt grafting. And plug skin connection and other methods. [0003] But all grafting methods in the past, from the relation between scion and rootstock, all can be referred to as positive grafting, promptly they all are that scion is grafted on rootstock, rather than opposite. [0004] The above grafting m...

Problems solved by technology

[0005] The technical problem to be solved and the technical task proposed by the present invention are to overcome the defects of the existing grafting methods, such as the slow healing of some joints and the low survival rate and preservation rate of trees grafted at high positions, and the defects of dying again after survival, and provide a kind of ear anvil reverse grafting method
