Abstract

The invention relates to the technical field of shaping pruning in fruit tree cultivation, in particular to a cultivation method for main branches of spindle-shaped apple trees. The method comprises the following specific steps that in the germination stage, main branches with the length larger than 70 cm is subjected to ring girdling multiple times; in the growth period of young sprouts, when thelength of branches on the main branches reaches 3-5 cm, the main branches are subjected to branch pulling and angle opening; when the length of the branches on the main branches reaches 10-15 cm, sprout torsion is conducted. According to the cultivation method for the main branches, multi-time ring girdling is matched with branch pulling and angle opening and sprout torsion in specific time, a large number of medium and short branches which are even in distribution, moderate and robust can be formed on the main branches, formation of long branches or super-long branches is reduced, early yield, high yield and stable yield of the apple spindle-shaped trees can be achieved, and the growth vigour of the main branches in the next year and in the later period is controlled. The cultivation method is easy to implement and control and saves labor and time.

Description

technical field

[0001] The invention relates to the technical field of shaping and pruning in fruit tree cultivation, in particular to a method for cultivating apple spindle tree-shaped main branches. Background technique

[0002] Apple tree shaping and pruning is a highly technical work in the comprehensive management of apple orchards. Its purpose is to form a certain tree structure and group structure, adjust tree balance, improve ventilation and light transmission conditions, and increase yield and quality. Cultivation is one of the most important links in apple tree shaping and pruning technology. It is a technology with relatively complicated technology, relatively labor-intensive operation and relatively long cycle in apple shaping and pruning.

[0003] With the innovation and development of high-quality and high-yield cultivation techniques for apples, the spindle-shaped tree shape has been widely used in production, and the application rate of new planting gardens h...

Examples

Embodiment 1

[0026] This embodiment provides a method for cultivating the main branch of an apple spindle tree. The implementation object of this embodiment is the apple sapling garden planted in Pingshan Yuanfang in 2016, and the variety is Octagonal Begonia / SH3 / Jihong (long branch type+ dwarf middle stock), the plant spacing is 2 meters, the row spacing is 4 meters, and the fertilizer and water management is better.

[0027] In 2017, the trunk of the apple tree was visually damaged (such as Figure 1A , Figure 1B shown), heavy short cut (such as Figure 1C shown) to promote the growth of main branches. When the upward vertical angle between the new main branch and the main trunk is less than 45°, pull the main branch and open the top branch to 40-60°C.

[0028] In the spring of 2018, the growth of the main branch is as follows Figure 1D shown. The main branches were randomly selected from the main branches with a length of 100-120 cm in the lower part of the apple tree in the orcha...
