Apple oblique-trunk multi-main-branch vertical plane tree form and shaping method thereof

Abstract

The invention discloses an apple oblique-trunk multi-main-branch vertical plane tree form, and belongs to the technical field of fruit tree shaping. The apple oblique-trunk multi-main-branch verticalplane tree form comprises a trunk, a central trunk and main branches, the height of the tree is 2 m, the trunk grows in an oblique state, the base of the central trunk grows in an oblique state, the front end of the central trunk grows in a horizontal state, the main branches grow upwards in a mode of being perpendicular to the ground and are evenly distributed along the central trunk at intervals, and 8-10 main branches grow in parallel. According to the apple oblique-trunk multi-main-branch vertical plane tree form and the shaping method thereof, the tree form is beneficial for dispersing the growth vigor of a tree body to the multiple vertical main branches, and transformation from vegetative growth to reproductive growth of the tree body is promoted; the plane fruiting tree form is beneficial for intercepting more light energy, light distribution of the tree body is uniform and consistent, leaf fertilizers and pesticide are distributed more uniformly in the tree body, fruits are good in coloring and high in quality, the height of the oblique-trunk multi-main-branch vertical plane tree form is kept at 2 m, the fruits can be picked when a person stands on the ground and stretchesout the hand, and mechanical pruning, flower thinning, fruit thinning and robot picking are convenient to achieve.

Description

technical field [0001] The invention belongs to the technical field of fruit tree shaping, and specifically refers to an apple oblique tree shape with multiple main branches and a vertical plane tree shape and a shaping method thereof. Background technique [0002] Apple is the dominant and pillar industry of my country's fruit tree industry. my country is the world's largest producer and consumer of apples. In 2018, the cultivated area reached 31.08 million mu, and the output reached 39.24 million tons, accounting for about 53% and 57% of the world's apple cultivated area and output, respectively. Even so, my country is not yet a strong production country, and there is still a certain gap with the world's advanced production countries. It needs to make great efforts in comprehensive management to catch up. Among them, there are many problems in plastic pruning. [0003] More than 80% of the apple orchards in my country are sparsely planted with arbor anvils, and the shapi...

AI Technical Summary

Problems solved by technology

Currently, a technician earns 150-200 yuan for cutting trees for one day, and 450-800 yuan for an acre of land. This is an unbearable burden for fruit farmers who currently have low apple prices and low returns.

[0004] At present, most of the tree shapes used in my country's newly built orchards with short stock and dense planting are spindle-shaped. Compared with the evacuated layered shape, the structure becomes simpler, and the shaping technology tends to be simplified, but it is still a 3D tree shape. Except for the fruits on the periphery of the canopy, The inner fruit is difficult to be picked by robots due to the occlusion of branches and leaves
