Reverse branch pulling device and method for close planting pear garden

Abstract

The invention discloses a reverse branch pulling device and a method for a close planting pear garden. The reverse branch pulling device comprises a clamping ring, at least one branch sleeve and supporting rods. The clamping ring is configured to be tightly hooped on a pear tree trunk during branch pulling; the branch sleeves are configured to sleeve a branch when the branch is pulled; the number of the supporting rods is equal to the number of the branch sleeves; the supporting rods are of a telescopic structure; and the supporting rods are movably connected between the clamping ring and the branch sleeves and are configured to conduct telescopic adjustment during branch pulling so as to adjust the included angle between the branches and the pear tree trunk to range from 80 degrees to 90 degrees after the branches are pulled in the direction opposite to the growth direction of the branches. According to the reverse branch pulling device for the close planting pear garden, the multiple branch sleeves are arranged according to the number of the branches, the supporting rods are movably connected between the clamping ring and the branch sleeves, and the branches are stroked and pressed by adjusting the length of the supporting rods and roughly opposite to the growth direction of the branches, so that the branches are fixed in a reverse nearly horizontal state, and reverse branch pulling is completed; and the supporting rods are of a telescopic structure, so that the branch pulling angle and direction can be adjusted along with growth of the branches, labor is saved, efficiency is achieved, the branch pulling effect is stable and reliable, and the cost is low.

Description

technical field [0001] The invention relates to a device and method for reverse branch pulling in densely planted pear orchards, belonging to the technical field of agriculture. Background technique [0002] Traditional pear trees are tall and tall, resulting in time-consuming and labor-intensive work such as spraying and picking, which does not meet the current labor-saving and simplified production requirements. Densely planted pear orchards (trunk shape, slender spindle shape) have the advantages of high yield, good fruit quality, easy management, labor saving and high efficiency, and are one of the development directions of modern pear orchards. In order to build the tree shape, pulling branches is a major task in densely planted pear orchards (trunk shape, slender spindle shape), and the workload is heavy. Due to the strong uprightness of pear branches and small footings, the traditional method of pulling branches is likely to cause branches to split. crack, break. ...

AI Technical Summary

Problems solved by technology

Existing methods are difficult to change the branch splitting or fracture that occurs in the pear tree branching process, and the pear tree branches are still growing vigorously after branching, and corresponding measures must be taken to control the vigorous growth of the branches. Therefore, it is necessary to study a labor-saving, A branch pulling method that is not easy to cause branches to split or break and controls the growth of branches
