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 method for breeding apple seedlings, which is characterized in that it comprises the following steps: (1) selecting the rootstock and the scion; (2) storing the rootstock and the scion; (3) processing before grafting; (4) carrying out Branch grafting; (5) field cuttings; (6) until seedlings are formed. The advantages of the present invention are: 1. Changing single bud grafting to branch grafting, the growth of branch grafting will be obviously better than that of single bud grafting. 2. Shorten the seedling raising time by half; reduce the production cost; (3) Realize factory batch and large-scale seedling raising. 3. The intermediate stock seedlings are propagated from basal stock seedlings to vegetative propagation. The seedlings are all vegetatively propagated, so as to ensure that the tree size is relatively consistent in production and cultivation. Due to the shortened seedling time, my country has increased the number of common apple seedlings and intermediate stock. The rate of application of vegetative root seedlings to stock.

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 ...
