Description

Technical Field

[0001] The invention relates to the technical field of fruit tree cultivation and fruit tree ecology, and in particular to a light and simplified branch pulling device and a branch pulling method for fruit trees. Background Art

[0002] Branch pulling is an important method for shaping young fruit trees and managing grafted trees, and it is a key method for regulating tree and branch vigor. In the early stages of growth, young trees and grafted trees are generally supported with toothpicks to open the base angle. As the branches continue to grow, branch pulling or bracing is required.

[0003] Conventional branch pulling is time-consuming, labor-intensive, and material-intensive, and is slow. When the orchard is large, it is impossible to pull all the branches to a certain angle in time to promote flowering.

[0004] For example, the Chinese invention patent application document with the number 201710034835.2 discloses a method for opening the waist angle during the shaping of young pear trees, comprising:

[0005] Step 1: Open the base angle. When the new shoots stimulated by the central stem grow to 16-20 cm, use a support rod with a length of 55-70 mm, a diameter of 1-5 mm, and sharp ends to open the base angle. The base angle is 65-80 °. Press the new shoot branches until the new shoot branches and the central stem are 70-90 °. First, insert one end of the support rod into the phloem of the central stem, and then insert the other end of the support rod into the phloem of the new shoot branches.

[0006] Step 2: Open the waist angle. When the new shoots stimulated by the central stem grow to 30-35 cm, use a bamboo stick with a length of 35-40 cm and a diameter of 4-5 mm to open the waist angle. The angle of the waist angle is 70-90°. Insert one end of the bamboo stick into the phloem of the central stem and the other end of the bamboo stick into the phloem of the new shoot.

[0007] The prior art discloses a method for opening the waist angle during the shaping of young pear trees. Due to the existence of apical dominance, as the branches continue to grow, the length of the branches at the base of the pear tree is generally longer than that of the branches in the middle and upper parts. These longer branches are no longer suitable for opening the waist angle. In production, these branches are often pulled up to the main trunk, but this is inconvenient to operate and it is difficult to achieve the ideal angle and orientation. For branches that cannot be pulled up to the main trunk, thicker ground stakes are nailed or iron wire is laid along the ground near the outer edge of the crown to pull the branches. However, ground stakes or laying iron wire are inconvenient for both mechanization and manual operation. In pear orchards covered with ground cloth for weed prevention and moisture conservation, the ground cloth will cause significant damage. Branch pulling tools such as branch pullers cannot meet the technical requirements. Therefore, in production, for these branches, the method of leaving stakes during winter pruning and thinning out and re-branching is generally adopted. This wastes tree nutrients, causes wounds, is susceptible to disease infection, and affects early yields.

[0008] For example, the patent application file with the Chinese invention patent application number 201711189400.1 discloses a method for pulling branches in the shaping process of pear tree saplings: bamboo sticks with a length of 35-40 cm and a diameter of 4-5 mm are used as ground anchors, without cutting, the sharp end is inserted into the soil by hand, the pulling direction is opposite to the branch direction, and the ground part is left with 1-3 cm.

[0009] However, with the increasing labor cost year by year, the aging problem of employees is increasingly prominent, and the ideal pulling period is limited, so that the work efficiency of workers decreases under the long-term high labor intensity and pressure.
