Dwarf fruit tree trunk shape, its forming method and high-density orchard construction method

Abstract

A main branch shape of short-planted fruit tree, comprising a strong main branch, 50-60 horizontal fruit branches with different length from 3 cm to 60 cm are directly inserted in the main branch with the distance of its branch height to surface being 40-60 cm, the roughness degree ratio between main branch and fruit branch is 5-20:1, the diameter of crown is smaller than 1.3 meter, and tree height is between 2 and 3 meter. The process comprises planting middle branch, carving bud, keeping fruit and flower blooming, controlling branch growth to form crown shape, the plant line distance of apple tree can be smaller than 1*3 meter to reach the close planting degree per mou of 100-550 strains; the plant line distance of peach tree can be smaller than 1*2 meter to reach the close planting degree per mou of 100-550 strains; in orchard, natural weed growth and artificial weed growing can be implemented. The fruit branch grows surround main branch, the irradiation of fruit is longer and, fruit size is uniform and quality is good. The method makes full use of natural condition and reaches purpose of stable and high production.

Description

Technical field:

[0001] The invention belongs to the cultivation of fruit trees, and in particular relates to a dwarf fruit tree trunk shape, a forming method and a high-density orchard construction method. Background technique:

[0002] At present, the shape of apple trees in China can be roughly divided into three categories: the first category is a small canopy with a row spacing of 5 meters, and the lower part is three main branches, and the upper part is spindle-shaped; the second category is a row spacing of 4 meters, and most of them are free spindles. and slender spindle-shaped; the third category is 3 meters apart or denser, mostly slender spindle-shaped or trunk-shaped. The planting density is only a dozen or 20 or 30 trees per mu. With the development of fruit tree technology, the planting density of apple trees has changed from the original dozen to dozens to hundreds of trees, and the tree shape has evolved from three main branches to spinning. The shape of the...
