Problems solved by technology

Frame cultivation reduces the height of the tree to a certain extent and ensures the quality of the fruit. However, these tree shapes are relatively difficult to reshape, and it is more difficult to induce and arrange the fruiting branches, especially the shape of the tree shape of the horizontal scaffolding takes longer to complete. , poor early fertility
In addition, the horizontal scaffolding requires orchard workers to face up and raise their hands, which is very laborious; the scaffolding that extends obliquely between the rows, such as a Y shape, reduces the difficulty of operation for the operators, but hinders mechanical operations to a certain extent

Embodiment 1

[0024] Such as Figure 1 ~ Figure 3 As shown, a pear tree "comb-shaped fence" tree shape, the total height of the pear tree is 3m, the height of the central trunk of the pear tree is 0.3m, two main branches are equipped on both sides of the central trunk, and the length of the main branch is 1.5m. The angle between the base of the main branch and the horizontal direction is 30°, and the front end of the main branch is horizontal; the main branch is equipped with 4 upright fruiting branches, and the branches spread out like comb teeth on the main branch. The distance is 0.3m.

[0025] The method for shaping the "comb-shaped fence" tree shape of the pear tree includes the following steps:

[0026] Step 1. Elevated erection: A 4m long steel pipe is set every 9m in the planting row. The steel pipe is buried 0.5m underground and fixed with reinforced concrete; the distance between the steel pipe and the ground is 0.75m, 1.5m, 2.5m and 3.5m Holes were drilled at the positions, and the ...

Embodiment 2

[0038] A kind of pear tree "comb-shaped fence" tree shape, the total height of the pear tree is 3.5m, the height of the central trunk of the pear tree is 0.4m, and two main branches are equipped on both sides of the central trunk. The length of the main branch is 1.5m. The angle between the base and the horizontal is 30°, and the front end of the main branch is horizontal; the main branch is equipped with 4 upright fruiting branches, and the branches spread out like comb teeth on the main branch, and the distance between the branches is 0.3m.

[0039] The method for shaping the "comb-shaped fence" tree shape of the pear tree includes the following steps:

[0040] Step 1. Elevated erection: A 4m long steel pipe is set every 9m in the planting row. The steel pipe is buried 0.5m underground and fixed with reinforced concrete; the distance between the steel pipe and the ground is 0.75m, 1.5m, 2.5m and 3.5m Holes were drilled at the positions, and the wire was pulled to fix the main br...

Abstract

The invention belongs to the technical field of pomology, and relates to a comb-shaped fence wall tree shape of a pear tree and a shaping method of the shape. The total height of the pear tree does not exceed 3.5 m, the height of the central trunk of the pear tree is 0.3-0.4 m, two main branches are arranged on the two sides of the central trunk and are 1.5 m long, the included angle of the base part of each main branch and the horizontal direction is 30 degrees, the front end of each main branch is in a horizontal state, a plurality of straight fruiting branches are arranged on each main branch and spread on the main branch in a combtooth-shaped mode, and the distance between the fruiting branches is 0.3 m. By means of the tree shape, the plane fruiting of the shed-frame-shaped pear tree is changed into the compact type three-dimensional fruiting, the tree bears more fruits, the quality differences of fruits at different positions are small, and the yield is higher.

Description

Technical field [0001] The invention belongs to the technical field of fruit cultivation, and specifically relates to a pear tree "comb-shaped fence shape" tree shape and a shaping method thereof. Background technique [0002] Pear is an international crop of large fruit trees and the second largest deciduous fruit tree in my country. The cultivation area and output of pears in my country rank first in the world, accounting for more than 70% of the world. Traditionally, the cultivated tree shapes of pear trees in my country mainly include scattered layered, open-hearted, and spindle-shaped. These tree shapes are usually tall and inconvenient for field management operations, resulting in a gradual disorder of the tree shape, resulting in a decline in performance and fruit quality year by year. [0003] After the introduction of shelf cultivation in the 1990s, tree shapes such as horizontal trellis and Y-shaped appeared again. Shelf cultivation reduces the height of the tree to a ...
