Embodiment 1

[0025] Embodiment 1 Mature tree pruning

[0026] The experiment was carried out in 2016 and 2017 at the Jinniushan Experimental Demonstration Base of Shandong Provincial Fruit Tree Research Institute in Daiyue District, Tai'an City, Shandong Province. The blueberry variety is "Xilai", which was planted in 2012 as a 2-year-old seedling, with a row spacing of 1 meter x 2 meters.

[0027] 10 blueberry plants were selected for pruning in the test plot, including 5 plants with strong tree vigor and 5 plants with weak tree vigor. Prune the vigorous and long branches in summer; when pruning in winter, thin out the basal branches that germinated in that year, and shrink the branches that are too high to 2-3 years old branches to control the height of the tree; Branches, overlapping branches, intersecting branches in the canopy, and diseased and insect branches; open to the tree posture: remove weak branches for moderately growing trees and keep strong branches; cut excessively tall b...

Embodiment 2

[0031] Example 2 Rejuvenation and pruning of mature trees

[0032] The experiment was carried out from 2015 to 2018 at the Jinniushan Experimental Demonstration Base of Shandong Fruit Tree Research Institute in Daiyue District, Tai'an City, Shandong Province. The blueberry variety is "Xilai", which was planted in 2010 as a 2-year-old seedling, with a row spacing of 1 meter x 2 meters.

[0033] 10 blueberry plants were selected for pruning in the test plot, including 5 plants with strong tree vigor and 5 plants with weak tree vigor. Since the beginning of winter pruning in 2015, the aging main branches have been renewed and rejuvenated. For about 1 / 3 of the aging main branches, close to the ground and thin out; the aging fruiting branch group is cut to the part below the first fruiting branch of the fruiting branch group, and the strong fruiting branch group is kept; the same age tree is pruned in summer prune. By pruning, the tree structure is 1.8-2m in height, 1.3-1.5m in ...

Embodiment 3

[0037] Embodiment 3 young tree pruning

[0038] The experiment was carried out in 2015 and 2016 at the Daidong Experimental Demonstration Base of Shandong Fruit Tree Research Institute in Taishan District, Tai'an City, Shandong Province. The blueberry variety is "Xilai", which was planted in 2013 as a 2-year-old seedling, with a row spacing of 1 meter x 2 meters.

[0039] 10 blueberry plants were selected for pruning in the test plot, including 5 plants with strong tree vigor and 5 plants with weak tree vigor. When pruning in the winter of 2015, remove redundant basal branches, drooping branches, thin and weak branches, over-dense branches, overlapping branches, cross branches in the canopy, and diseased and insect branches; keep the extended head of the main branch, and lightly cut the remaining branches to cultivate fruiting branches Coordinating the tree vigor with the amount of fruit: for a vigorous tree body, leave more flower buds, and control the yield per plant in the...

Abstract

The invention provides a pruning method for shaping the arbuscular shape of open-field blueberries. Different summer and winter pruning modes are adopted for tree bodies with different growth states,the contradiction between nutrition growth and reproductive growth of the tree bodies is coordinated, and an updating method combining a process of cultivating new main branches according to a plan and a process of removing aged main branches is adopted, so that large fluctuation of the fruiting amount is avoided, high yields and stable yields in successive years are ensured, and fruiting years and life spans of the tree bodies are effectively prolonged.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a method for shaping and pruning high-shrub blueberry bushes in the open field. Background technique [0002] Blueberry (Blueberry) belongs to Rhododendron (Ericaceae) Vaccinium (Vaccinium) plant, is a kind of emerging fruit tree. Although blueberry is a kind of perennial shrub fruit tree, if it is not pruned, it will lead to dense branches, closed canopy, no ventilation and light transmission, and low light utilization rate, which will seriously affect fruit yield and quality. my country's blueberry industry started late, and the pruning technology is not yet perfect. [0003] In the Chinese patent CN 201410790617.8, the method of shaping and pruning blueberries in the north discloses a method of shaping and pruning blueberries cultivated in open fields, cold sheds, and solar greenhouses. For blueberries that have been planted in the open fields for many years, ...
