Problems solved by technology

[0007] In the traditional tree shape management method of seedlings in breeding nurseries, because the fixed stem stimulates the upward growth of terminal buds, promotes branching, and increases branch expansion, not only does the single seedling take up a lot of space, but also the root , reducing the nutrient shu

Embodiment 1

[0025] For apricot seedlings hybridized with 'Chuanzhihong'×'Golden Sun', the planting spacing×narrow row spacing×wide row spacing is 1.0m×1.0m×2.5m, and 266 plants are planted per mu. The management method is as follows:

[0026] Seedlings are not fixed to dry, no buds are wiped under the plastic belt, no main stem is left, and the extension head of the central stem continues to grow. Since the first year is not fixed, and the extension head of the central stem is not cut short in the future, the growth volume decreases year by year;

[0027] In the first year of planting, when pruning in winter after leaf fall and before germination, the side branches shorter than 5 cm are not pruned, and the side branches longer than 5 cm are cut short at 5-10 cm. degree ratio)>3 thick branches are cut short by 5 cm, and thin branches with a branch-to-trunk ratio≤3 are cut short by 10 cm; in the second year after planting, the germinated side branches are cut in winter, and the winter cut in...

Abstract

The invention provides a management method for breeding seedlings, belonging to the technical field of fruit tree breeding, which comprises the following steps: 1) densely planting seedlings in two rows in a nursery; 2) carrying out winter shear in that first year after the seedling is planted, wherein the winter shear comprises the following steps of: cutting the lateral branches with the lengthbeing equal to or more than 5 cm into short sections at the positions of 4 to 12 cm; the time of winter shear is after leaf defoliation of seedlings before germination; 3) carrying out winter shear onthat germinated lateral branches in the second year after the seedling is planted, wherein the shear comprises cutting erect and overlapping branches, retaining oblique, horizontal and pendulous branches, and continuously shortening the lateral branches with the length being equal to or more than 5 cm at the positions of 4 to 12 cm; 4) in the later each year, carrying out winter shear only on theside branch as in the step 3). The management method can reduce the land space occupied by each seedling, greatly increase the number of plant per unit area, reduce the height of the tree body, shorten the breeding period, and make the juvenile span measurement more accurate.

Description

technical field [0001] The invention belongs to the technical field of fruit tree breeding, in particular to a management method for breeding seedlings. Background technique [0002] The seedlings used for fruit tree breeding are seedlings propagated by seeds, including selected seedlings and cross-breeding seedlings, which are planted in field breeding nurseries, and can only bear fruit after the juvenile period (Juvenile period) of the fruit tree seedlings reaches the adult period (Adult period). As a result, after preliminary selection, re-selection, final selection or variety comparison test, regional test, production test, expert identification, variety approval or application for protection of variety rights, it can become a new variety. [0003] Traditional seedlings (seeds formed by natural or open pollination, or seedlings formed by cross-pollinated seeds germinated after stratification) are first planted in the breeding nursery, after growth and development, they p...
