Embodiment 1

[0019] Germination: Rinse a large number of dormant apple hybrid seeds twice with clean water in early February, drain, spread evenly on the enamel plate, the thickness of the spread is not more than 1 cm, line the seeds with 2 layers of wet cotton towels above and below, and place them manually. Germination in climate chamber. The temperature was controlled at 26±1°C, the relative humidity was 90%, and there was no light. All hybrid seeds germinated within 10 days. During the germination process, it is required to take out the seeds and towels every 24 hours, rinse them twice with clean water, and then restore them to their original state, and quickly put them back into the artificial climate box. The synchronization of fruit tree hybrid seed germination is poor. Therefore, from the second day of germination, the germinated seeds should be selected 1 or 2 times a day for sowing in time. It is more suitable for sowing when the germ grows to 0.5 cm.

Embodiment 2

[0028] Germination: Rinse a large number of dormant chestnut hybrid seeds twice with water in early February, drain, and evenly spread them on an enamel plate with a thickness of no more than 1 cm. The seeds are lined with 2 layers of wet cotton towels above and below, and placed in an artificial climate Germinate in box. The temperature was controlled at 26±1°C, the relative humidity was 80%, and there was no light. Hybrid seeds generally begin to germinate after 24 hours, and all germinate within 10 days. During the germination process, it is required to take out the seeds and towels every 24 hours, rinse them twice with clean water, and then restore them to their original state, and quickly put them back into the artificial climate box. The synchronization of germination of fruit tree hybrid seeds is poor, so from the second day of germination, the germinated seeds should be selected 1 or 2 times a day for timely sowing. Chestnut hybrid seed germ growth to 0.5cm is more s...

Embodiment 3

[0037]Pregermination: From late January to mid-February, rinse a large number of dormant peach hybrid seeds with clean water twice, drain, and evenly spread them on an enamel plate with a thickness of no more than 1 cm. The seeds are lined with 2 layers of wet pure cotton above and below. Towels, placed in an artificial climate box to accelerate germination. The temperature is controlled at 20-30°C, the relative humidity is 80%-95%, and there is no light. Hybrid seeds generally begin to germinate after 24 hours, and all germinate within 10 days. During the germination process, it is required to take out the seeds and towels every 24 hours, rinse them twice with clean water, and then restore them to their original state, and quickly put them back into the artificial climate box. The synchronization of germination of fruit tree hybrid seeds is poor, so from the second day of germination, the germinated seeds should be selected 1 or 2 times a day for timely sowing. It is more s...

Abstract

The invention discloses a method for shortening the juvenescent phase of fruit trees, which comprises accelerating germination, seeding, port transferring, seedling adaptation, field planting and training and pruning. Adopting the technology in the project, the peach seedling tree can pass the juvenescent phase in the very year of seeding and enter the adult vegetative phase, while the seedling trees of apple and chestnut, etc., can pass the juvenescent phase in the second year after the seedling tree seeding and enter the adult vegetative phase. Shortening the juvenescent phase of seedling trees of fruit crops has an important significance for shortening the breeding cycle of fruit trees and promoting the career development of fruit trees.

Description

technical field [0001] The invention relates to a method for shortening the infancy of fruit trees, shortening the time required for the fruit trees to bloom and bear fruit, so that the fruit trees can quickly pass through the infancy. Background technique [0002] The developmental stage of fruit trees that do not have the ability to form flowers is called childhood. It takes several years or even more than ten years for fruit trees to grow from sowing to fruiting. This is a technical bottleneck for improving the efficiency of fruit tree breeding. In order to shorten the time required for the flowering and fruiting of seed trees, it is necessary to promote vegetative growth in the early stage, so that it can pass through the childhood stage quickly and flower and bear fruit earlier, thereby shortening the breeding cycle. [0003] Shortening the childhood period of fruit tree crops is of great significance to shorten the breeding cycle of fruit trees and promote the developm...
