High photosynthetic efficiency tree form cultivation method for peach trees with multiple semi-upright main branches and without side branches

Abstract

The invention discloses a high photosynthetic efficiency tree form cultivation method for peach trees with multiple semi-upright main branches and without side branches. The method comprises the following steps: culturing 2-4 main branches for each plant according to the difference of tree spacing, wherein bearing branches or small bearing branches are directly inserted in the main branches, and the peach trees do not have side branches or only have a small number of side branches; and trimming and managing each main branch according to the shape of the trunk, and carrying out single branch updating, wherein each main branch is semi-upright, and an included angle between each main branch and the perpendicular direction is 20-30 degrees. According to the method provided by the invention, the number of branches of a middle lower portion of each peach tree is increased, a traditional planar fruitage mode is changed into a stereo fruitage mode, so that growth characteristics of peaches are met, and the peach trees are shaped quickly and easy to be trimmed; channels among rows are clear, and time and labor are saved during the operation in the field; branches and leaves of tree bodies are distributed uniformly, ventilation and light transmittance are realized, so that photosynthesis of leaves is good, the tree bodies grow strongly, and plant diseases and insect pests are few; and the method facilitates popularization of existing orchard machinery to peach orchards, and mechanical management is facilitated.

Description

technical field [0001] The invention belongs to the field of crop cultivation, and in particular relates to a method for cultivating peach trees in a semi-upright, multi-main, sideless, high-light-efficiency tree shape. Background technique [0002] The topography of Taoyuan in my country covers various site conditions such as plains, hills, and mountains, and the planting density ranges from 22 plants per mu (5m x 6m) to 333 plants per mu (1m x 2m) , The shaping methods include three main branches in a natural happy shape, two main branches in a natural happy shape, a small crown with multiple main branches in a cup shape, and a trunk shape, etc. The crown can be high or low, and the tree shape can be upright or open. But generally speaking, it can be divided into four categories, namely, sparsely planted large crown type, medium-density cup-shaped type, medium-density V-shaped type and high-density trunk type: [0003] 1. Large crown and sparse planting type [0004] It i...

Problems solved by technology

[0022] The purpose of the present invention is to provide a semi-upright, multi-main, sideless and high-light-efficiency tree cultivation method for peach trees, aiming to solve the existing peach cultivation methods, the number of branches in the middle and lower parts of the peach trees is small, and most of them are concentrated on the top floor, and the rows of the peach orchard The passage is not clear, the field work is time-consuming and labor-intensive, the branches and leaves in the canopy are dense, there is no ventilation and light transmission, frequent pests and diseases, and the degree of mechanization is low.
