Problems solved by technology

As a result, closed apple gardens have the following defects: poor light, difficulty in flowering, late results, poor quality, serious pests and diseases, inconvenient field operation and management, increased production costs, and declining benefits
However, the canopy of the canopy orchard treated in this way is too large, which cannot solve the problem of light in the orchard, and is prone to a large number of rot diseases

Embodiment Construction

[0029] The invention discloses a three-branch grafting and tree shape modification method for an apple canopy orchard. Through three-branch grafting on the base of fruit trees, a stable tree body and tree shape are formed, and the tree height can reach about 2.5 meters in that year. From the second year, the central trunk formed can be pruned according to the requirements of different tree shapes according to the needs of the tree shape to be modified. The present invention will be described in detail below in conjunction with specific embodiments, which are explanations rather than limitations of the present invention.

[0030] The canopy gardens for transformation are: 10-15-year-old arborization planted with more than 50 closed gardens per mu, or closed gardens with more than 80 trees planted per mu with short anvils and all intermediate anvils buried in the soil; it was found that the branch handover was serious , the light conditions are poor, and field operations are dif...

Abstract

The invention relates to technology to transform a closed apple orchard through the combination of grafting and tree form reshaping and discloses a grafting and tree form reshaping method of three-branch inarching of the closed apple orchard. Three-branch grafting is carried out at the root of a fruit tree, three scions are grafted at the subcutaneous section and comprise one long scion and two short scions; after the grafted branch buds, the central tree trunk is formed through three-branch inarching, the height of the tree in the current year can reach up to about 2.5m, and the formed central tree trunk can be pruned according to different requirements of the tree form to be reshaped from the next year, thereby realizing improvement of fruit tree breed and fruit tree form in a short period of time.

Description

technical field [0001] The invention belongs to the technical field of transformation of closed apple canopy orchards, and relates to a technology for transforming closed apple canopy orchards by combining grafting and tree shape modification, in particular to a method for grafting and tree shape modification of three branches of closed apple canopy orchards. Background technique [0002] The apple orchards planted after the 1990s in my country generally have the defects of excessive arborization planting density, joints between rows, crossing between plants, and poor ventilation and light transmission in the group. The middle stock of the dwarf stock orchard is all buried in the soil, and dwarfing becomes arborization. Improper selection of tree shape in densely planted gardens, non-standard shaping techniques, too high and too large tree crowns, poor individual ventilation and light transmission; unreasonable tree structure, uncoordinated growth, low trunk, thin middle tru...
