Embodiment Construction

[0028] The present invention will be further described in detail below in conjunction with specific embodiments, but the protection scope of the present invention is not limited to these embodiments, and all changes or equivalent substitutions that do not depart from the concept of the present invention are included within the protection scope of the present invention.

[0029] A kind of pruning type apple 4-5 main branch happy tree shape shaping and pruning method of the present invention comprises the following steps:

[0030] 1) Apple trees are planted at a density of 70-80 per 666.7 square meters. The rootstocks of apple grafted seedlings used for planting are arborization rootstocks, and the grafted varieties are short-branched apple varieties;

[0031] 2), Upright tree cultivation and pruning stage:

[0032] In the first 1-2 years of fruit tree planting, the cultivation of the trunk and backbone branches is the main focus, and the new shoots on the trunk are generally no...

Abstract

The invention relates to a 4-5 main branch open-center tree shape pruning method for short shoot type apple trees, belongs to the technical field of apple tree shape pruning and aims to provide an apple tree shape pruning method capable of realizing reasonable crown and leaf curtain illumination, excellent fruit quality and substantial prolonging of economic life of orchards to solve the technicalproblems. The method comprises the steps as follows: 1) apple trees are planted at the density of 70-80 plants every 666.7 square meters; 2) for apple orchards at the tree age of 1-5 years, dispersion layering or free spindle shape pruning is adopted for the apple trees, and 10-12 skeleton branches are reserved on each whole tree; 3) at the tree age of 6-10 years, branch lifting and central branch pruning are performed for the first time, at the tree age of 10 years, 6-7 main branches are reserved on each whole tree, and the length of fruit-bearing branch groups is 50-70 cm; 4) at the tree age of 11-30 years, branch lifting and central branch pruning are performed for the second time, the number of main branches is reduced year by year, and 4-5 main branches are reserved on each whole tree at the tree age of 20 years.

Description

technical field [0001] The invention discloses a pruning and pruning method for pruning apple trees with 4-5 main branches of short branches, and belongs to the technical field of apple tree pruning. Background technique [0002] The cultivated area of ​​apple arborization in my country accounts for more than 85% of the total area of ​​apples in the country, and its tree shape mostly adopts tree shapes such as small crown sparse layer, evacuated layered shape, and free spindle shape. The above-mentioned orchards with tree shaping and pruning have higher yields at the initial fruiting stage, but canopy closure and orchard canopy closure generally occur after entering the full fruit stage, resulting in a decline in fruit tree quality and economic benefits. Therefore, tree shape transformation is required. [0003] Short-branch apple varieties have developed rapidly in the past ten years because of their advantages such as short tree body, early fruit, early high yield, and goo...
