Malus crabapples root grafting breeding method

Abstract

The invention belongs to the seedling breeding field, particularly to a malus crabapples root grafting breeding method. The malus crabapples root grafting breeding method comprises the processes of stock selection, scion strip collection, grafting, grafting seedling planting and grafting seedling management. Main foots and side foots of Hubei crabapples seedlings are selected to serve as the stocks, the root grafting seedling growing is performed by a cleft grafting method, the specification management is performed in the late graft period, and the malus crabapples root grafting high-quality seedlings are cultivated. According to the malus crabapples root grafting breeding method, the grafting can be achieved in the indoor space and the operation is convenient, the efficiency is high, and the labor intensity is greatly reduced in comparison with the field grafting; the ordinary Hubei crabapples roots serve as the stocks and accordingly the resources are rich and the material selection is easy; the main foots and the side foots of the Hubei crabapples serve as the stocks, 6 to 7 root grafting stocks can be cut from a one-year Hubei crabapples seedling generally, and accordingly the propagation coefficient is improved.

Description

technical field [0001] The invention belongs to the field of nursery stock breeding, in particular to a root grafting breeding method for ornamental crabapple. Background technique [0002] Ornamental crabapple (Malus spp.) is a kind of fruit diameter less than 5cm in the Rosaceae Malus genus, and its branches, leaves, flowers or fruits have high ornamental value, including many species and subspecies varieties and varieties. With the development of economy and the improvement of material and cultural life, people have higher and higher requirements for urban environment. Therefore, in the process of environmental greening and beautification, higher requirements are put forward for the variety and quality of plants. And crabapple plants are increasingly paid attention to by people because of their beautiful tree shape, bright colors, rich cultural connotations, etc., and the application of crabapple is becoming more and more extensive. Expanding the breeding coefficient of...

Problems solved by technology

[0003] For the breeding of ornamental crabapple, the seedlings of octagonal crabapple and Hubei crabapple are often used as rootstocks for budding and branching. The disadvantage is that they all use the whole seedling or a sapling as the rootstock. In this way, a seedling can only be grafted One seedling has a low reproduction coefficient, which is far from meeting the production needs
