Branch stretching method in young pear shaping process

Abstract

The invention discloses a branch stretching method in the young pear shaping process. The method includes the following steps of 1, base angle opening; 2, waist angle opening; 3, branch angle opening,wherein in the end of June and beginning of July, before branches stop to grow, branches at pear bases with the length of 50 cm to 60 cm are selected and subjected to branch angle opening, and the selected branches are softened; 4, branch positioning, branch pressing or rotating, branch balance points of tensile force are found on the branches through the angle and the orientation of pressing orrotating the branches according to the even distribution requirements of branch space; 5, ground peg digging, wherein the inserting positions of ground pegs are connected with the branch balance points of the tensile force and the ground pegs according to the angle and the orientation of branch positioning in the step 4 through gunny bag lines or cloth strips, wherein the gunny bag lines or the cloth strips are connected with the branch balance points of the tensile force in a slipknot mode, and the gunny bag lines or the cloth strips are connected with the ground pegs in a hard-knot mode. Thebranch stretching method in the young pear shaping process is easy to apply and convenient to operate.

Description

technical field [0001] The invention relates to the fields of fruit tree cultivation and fruit tree ecology, in particular to a method for pulling branches in the pear young tree shaping process. Background technique [0002] The labor-saving cultivation mode of dense planting is the current development direction of China's pear industry, and all parts of China are in the stage of trial and exploration. According to the growth and fruiting status of saplings under different shaping methods, it is of great significance to select suitable tree shapes under different planting densities. The number of growing points is very critical to disperse the tree vigor and control the branch development. In order to further control the branch development, in the cultivation process of pear trees, the method of promoting flowering in advance, slowing down the potential with flowers and suppressing potential with fruit is often used. The main measure is to pull the branches so that the br...

Problems solved by technology

[0007] The prior art discloses a method for opening the waist angle of pear saplings. Due to the existence of the dominance of the top, as the branches continue to grow, the growth length of the base branches of pear trees is generally longer than that of the middle and upper branches, which is longer. It is no longer suitable to use the method of opening the waist angle for some branches. In the production, it is often used to pull the branches to the main trunk, but the operation is inconvenient, and it is difficult to achieve the ideal angle and orientation; Use ground prongs with thicker nails or lay iron wires near the ground on the periphery of the tree crown to pull branches, but ground prongs or laying iron wires are inconvenient for mechanization and manual operation. Large damage is caused, and the technical requirements cannot be met through branch pulling tools such as branch pullers

Therefore, for this part of the branches in production, the method of leaving prongs to remove them during winter pruning and re-growing branches is generally used, which wastes the nutrition of the tree body, causes wounds, is easy to be infected with diseases, and affects the yield in the early stage.
