A pear tree "comb-shaped hedge" tree shape and its shaping method

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 in particular relates to a "comb-hedge-shaped" tree shape of a pear tree and a shaping method thereof. Background technique [0002] Pear is an international bulk fruit tree crop, and it is also the second largest deciduous fruit tree in my country. The cultivated area and output of my country's pear rank first in the world, accounting for more than 70% of the world's total. Traditionally, the cultivated tree shapes of pear trees in my country mainly include evacuated layered, happy and spindle shapes. These tree shapes are usually tall and inconvenient for field management operations, resulting in gradual changes in the tree shape, resulting in a decline in performance and fruit quality year by year. [0003] After the introduction of trellis cultivation in the 1990s, tree shapes such as horizontal trellis and Y-shape appeared. Frame cultivation reduces the height of the tree to...

AI Technical Summary

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
