Method for reshaping pear trees

Abstract

The invention discloses a method for reshaping pear trees, relating to a method for reshaping fruit trees and comprising the following steps: (1) determining reasonable plantation density, wherein appropriately, the line spacing is 4m and the row spacing is 5-6m; (2) formulating an overall objective for culturing tree shapes, controlling the trunk height of a pear tree to be 0.7-0.8m and the distance away from the ground to be 0.8m, allocating two boughs along a progressive direction, and inducing horizontally; and allocating lateral branches at the two sides of the boughs, performing line spacing inducement through a mode for forming a dip angle of 45 degrees with the horizontal plane, and controlling the spacing between lateral branches to be 0.4-0.5m; (3) realizing tree shape culture by the steps of bough culturing and inducing, and reasonable allocating and trimming of lateral branches; and (4) constructing a framework adaptive to labor-saving reshaping, wherein the pear trees are V-shaped and U-shaped. The invention has the advantages as follows: (1) the reshaping technology has simple requirements and rapid speed; (2) the field operation is easy and has high efficiency; (3) the expansion of operation to an appropriate scale per capita is possible; and (4) the early-stage yielding ability is good.

Description

technical field [0001] The invention relates to a method for shaping fruit trees, in particular to a method for shaping sand pear trees that grow upright and have tall trees. Background technique [0002] Pear is one of the main fruit trees in my country. The cultivated area and output of pear trees rank first in the world. Among various fruit trees in my country, pear tree area and output are second to apples and citrus, ranking third. The south of the Yangtze River is a tropical and subtropical pear area, and the sand pear variety is mainly cultivated. In the pear area of ​​Yunnan-Guizhou Plateau, sand pear varieties are also mainly cultivated. my country's pear tree cultivation is traditionally based on layered heart-shaped shaping, mainly including evacuated layered shape (improved evacuated layered shape), spindle shape (slender spindle shape, improved spindle shape) and the like. These tree shapes have the advantages of complete tree structure, firm skeleton, long ...

Problems solved by technology

Therefore, many research institutes have changed the traditional layered pear tree cultivation into the domestic leading horizontal frame cultivation. Although the horizontal frame cultivation dwarfs the tree crown compared to the traditional arbor cultivation, it facilitates the operation and improves the fruit quality, but For people's operating comfort, it is still not ideal. It is really hard for the cervical spine and arms to work on their backs and raise their hands over their heads all day long.
