Embodiment 1

[0022] A method for breeding apple seedlings is applied in the breeding of seedlings from root stock by arborization in apple vegetative system, comprising the following steps:

[0023] (1) Selection of rootstock and scion: both the rootstock and the scion need to be picked from the scion nursery or tree in "heavy snow" for storage to avoid freezing damage. The rootstock is Japanese round-leaf crabapple. After the leaves are fallen, choose thick branches and cut them according to the production requirements of 15-25cm. This length should be added to the loss during grafting and bundled. Each bundle is 20. Do not disturb the polarity. And the orientation of the bud body of each branch is the same, and the lower end can be cut into a wedge shape for storage; the scion is the Fuji variety Yanfu 3, and in fact the current production and cultivation of apple varieties and rootstocks, such as dwarf rootstocks M9, M26 etc., can be propagated by this method.

[0024] (2) Store the ro...

Embodiment 2

[0067] A method for breeding apple seedlings is applied to the breeding of apple dwarfing intermediate stock seedlings or the breeding of apple dwarfing self-root stock dwarfing seedlings, comprising the following steps:

[0068] (1) Selection of rootstock and scion: base stock or dwarfed intermediate stock, and scion need to be picked from the scion nursery or tree in "heavy snow" for storage to avoid freezing damage. Step is the same as embodiment 1, but base stock branch is cut into 10-15cm, and described scion is Fuji series kind and is Yanfu 3, 2001 Fuji etc. The dwarf intermediate stock is M9, M26.

[0069] (2) Store rootstock and scion: store in sand or store in fresh-keeping warehouse. Anvil storage and processing steps are the same as in Example 1. The processing steps of M9 and M26 are stored with the scion of embodiment 1. If the base stock is not cut into sections before winter, it must also be cut one month before grafting, and the ditching and root-promoting t...

Abstract

The invention relates to a propagation method of apple seedlings, which is characterized by including the steps: firstly, selecting rootstocks and scions; secondly, storing the rootstocks and the scions; thirdly, performing pre-grafting treatment; fourthly, performing scion grafting; fifthly, performing cuttage on a field; and sixthly, obtaining seedlings. The propagation method has the advantages that firstly, scion grafting is used instead of single budding, so that growth vigor of seedlings subjected to scion grafting is evidently better than that of the seedlings subjected to single budding; secondly, seedling raising time is shortened, production cost is lowered, and factory large-scale raising of seedlings in batch is achieved; thirdly, inter-stock seedlings are propagated with rootstock seeds instead of vegetative propagation, seedling propagation is all subjected to vegetative propagation, and accordingly, uniform sizes of trees in terms of production and cultivation are guaranteed; and the seedling raising time is shortened, and accordingly the speed of applying common apple seedlings and inter-stock nutrimental root seedlings is increased in China.

Description

technical field [0001] The invention relates to a method for breeding forestry fruit tree seedlings, in particular to a method for breeding apple seedlings. Background technique [0002] At present, in the seedling breeding of ordinary apple seedlings and intermediate stock in my country, the base stock is used for breeding seedlings. The most commonly used base stock is octagonal crabapple, etc., which are all cross-pollinated plants. In fact, the phenomenon of separation of seedling traits Very serious, manifested in a variety of ways. Intermediate anvils and grafted varieties are grafted to plants bred from seeds, which will inevitably have different effects, resulting in different sizes of trees and irregular garden appearance. If you choose a base stock with good adaptability, strong stress resistance, high yield, and excellent affinity with the intermediate stock and varieties, use the method of vegetative propagation for breeding, and use the stem root system instead ...
