Multi-layered grafted tree and grafting method

Abstract

The invention relates to a grafted tree, in particular to a multi-layered grafted tree which is grafted in the current year and harvested next year and a grafting method. At present, walnut grafting is a traditional grafting method, grafting methods in the prior art are low in survival rate, grafting cuts are difficult to heal, overwintering is difficult, and economic benefits cannot be generated in time. The tree comprises a stock and multiple layers of scions grafted on the stock, and a grafting vertical groove is formed by stripping bark on the grafting portion of each layer on the stock; the lower half portions of the scions are cut to form long inclined faces, the backs of the long inclined faces at the lower ends of the scions are short inclined faces, and vertical faces are formed by stripping old bark from the upper ends of the short inclined faces and the long inclined faces; the long inclined faces, the short inclined faces and the vertical faces are inserted into the grafting vertical grooves of the stock. Grafting is easy and convenient to operate, the stock is slightly damaged, multi-layer grafting is achieved, and fruiting portions are increased. Healing is easy, the survival rate is as high as 90% or above, the tree can not be blown down by sand wind, the tree can safely overwinter 100%, and after-grafting fruiting is early and the yield is high.

Description

technical field [0001] The invention relates to a grafted tree body, in particular to a multi-layer grafted tree body and a grafting method for grafting in one year and harvesting in the next year. Background technique [0002] At present, walnut grafting is to transplant the buds or branches of an excellent variety to another walnut tree that grows robustly and is more adaptable to the local natural conditions. Grafting methods, and only grafted on the head of the rootstock, these grafting methods have a relatively low survival rate, complex grafting, serious injury to the rootstock, waste of more grafted cortex, small healing area of ​​grafting, difficult healing of grafting wounds, and easy blowing by wind and sand On the contrary, the management after grafting is unreasonable, and it is difficult to survive the winter. The fruiting rate of the grafting year is not high in the next year, and it will not enter the harvest period until a few years later, and cannot generate...

[0002] At present, walnut grafting is to transplant the buds or branches of an excellent variety to another walnut tree that grows robustly and is more adaptable to the local natural conditions. Grafting methods, and only grafted on the head of the rootstock, these grafting methods have a relatively low survival rate, complex grafting, serious injury to the rootstock, waste of more grafted cortex, small healing area of ​​grafting, difficult healing of grafting wounds, and easy blowing by wind and sand On the contrary, the management after grafting is unreasonable, and it is difficult to survive the winter. The fruiting rate of the grafting year is not high in the next year, and it will not enter the harvest period until a few years later, and cannot produce economic benefits in time.
