A Tree Shape and Shaping Method Suitable for Old Closed Apple Orchard Reconstruction

Abstract

The invention discloses a tree shape suitable for the reconstruction of old closed apple orchards, which is characterized in that the tree shape includes a primary trunk and a combination of branches arranged on it, and the combination of branches includes alternate whorls. The three main branches on the first-level trunk, and the second-level trunks respectively set on the three main branches. The multi-main branch tree shape is transformed into a multi-trunk tree shape by re-shrinking, and the canopy is compressed by remodeling to narrow the crown width, open the orchard passage, and simplify management.

Description

technical field [0001] The invention relates to the technical field of orchard planting management, in particular to a tree shape and shaping method suitable for the transformation of old closed apple orchards. Background technique [0002] With the development of my country's fruit tree industry, many orchards have gradually entered the aging process. With the expansion of the canopy, many problems have appeared, such as: closed canopy, intersecting branch groups between plants, dense outer canopy and hollow inner canopy, and tree canopy interior. Dry and aging; the fruiting part of the tree body moves outwards, there are almost no fruiting branches in the inner chamber, the three-dimensional fruiting ability is poor, the yield and quality are reduced, and the tree body is weak; the orchard passage is blocked, which is not conducive to the current mechanized operation. The above problems are based on evacuation and stratification. It is especially prominent in orchards with m...

Problems solved by technology

[0002] With the development of my country's fruit tree industry, many orchards have gradually entered the aging process. With the expansion of the canopy, many problems have appeared, such as: closed canopy, intersecting branch groups between plants, dense outer canopy and hollow inner canopy, and tree canopy interior. Dry and aging; the fruiting part of the tree body moves outwards, there are almost no fruiting branches in the inner chamber, the three-dimensional fruiting ability is poor, the yield and quality are reduced, and the tree body is weak; the orchard passage is blocked, which is not conducive to the current mechanized operation. The above problems are based on evacuation and stratification. Especially in orchards with more than 20 years old tree shape

[0003] In order to solve the above problems, there are mainly two methods. One is to cut down trees and rebuild. Although this method can completely solve the above problems, the construction period is long, the initial investment is large, and the economic benefits are difficult to guarantee. It is unbearable for fruit farmers. There is still the danger of repeated cropping in the construction of orchards; the second is to achieve the purpose of orchard transformation through pruning methods such as thinning and dropping the head and lifting the stem, but they are not very successful and cannot fundamentally solve the problem
