Two-main-branch natural open-centered peach tree form and forming method

Abstract

The invention provides a two-main-branch natural open-centered peach tree form. The form comprises a trunk, and a first main branch and a second main branch which are opposite in growth and extensiondirection are arranged on the trunk; the first main branch is provided with at least one first main branch first branch and at least one first main branch second branch, and the growth and extension directions of the first main branch first branch and the first main branch second branch on the first main branch are opposite; and the second main branch is provided with at least one second main branch first branch and at least one second main branch second branch, and the growth and extension directions of the second main branch first branch and the second main branch second branch on the secondmain branch are opposite. The invention further provides a forming method of the two-main-branch natural open-centered peach tree form. According to the two-main-branch natural open-centered peach tree form and the forming method, the forming time of the tree form is short, and the two-main-branch natural open-centered peach tree form has the advantages of being high in lighting effect, high in quality, high in yield and stable in yield.

Description

technical field [0001] The invention belongs to the technical field of fruit tree planting management, and relates to a natural open-hearted peach tree shape with two main branches and a forming method. Background technique [0002] Peach is a kind of global bulk fruit, which spreads in more than 70 countries and regions in the world. The peach producing areas are mainly concentrated between 30°-40° south latitude and north latitude. my country is the largest peach producer in the world, accounting for the world's cultivation more than 50% of the area. The current peach planting process is characterized by high input of labor and agricultural materials (labor costs caused by aging, land rental costs, etc.), high yield and quality in the early stage and low in the later stage, and the life of the orchard is getting shorter and shorter; With the improvement of the level, the demand for high-quality fruits by mass consumption is far greater than that of ordinary fruits. Peaches...

AI Technical Summary

Problems solved by technology

Disadvantages: The technical requirements for tree-shaped skeleton cultivation are relatively high. If it is not done properly, it is prone to problems such as splitting or no sharpness of the main trunk (branch), small bearing capacity, deformation of the main trunk, and affecting mechanized operation.

Disadvantages: Entering the high-yield period is a little late, and the skeleton culture requires careful operation, and the yield is also low

Disadvantages: Pruning requires too much technology for actual operation, once the pruning technology is not up to the standard, it is easy to clump

At the same time, it is difficult to recover the tree body and tree posture after opening. If the tree shape is corrected by heavy pruning, the peach tree wounds will heal slowly, and after heavy pruning, it is prone to dieback disease, perforation disease, etc., and finally the lower branches are prone to become more and more weak. Weakened, the life of the tree is getting shorter and shorter, it is difficult to renew the branch group and the phenomenon of disconnection occurs, and then the fruit becomes smaller, the color becomes worse, the yield decreases, the fruit is good and the fruit is poor, and the commodity rate and quality rate drop sharply
