Problems solved by technology

But this kind of tree shape is cultivated in layers, and the growth of branches is difficult to control.
And it is prone to premature aging after forming, so it is difficult to apply in production

Embodiment Construction

[0041] The present invention discloses a new high-slender spindle tree shape suitable for short stock, wide rows and densely planted orchards. The present invention will be described in detail below in conjunction with the description of the tree structure and the method of pruning. The description is an explanation of the present invention. Not limited.

[0042] The trunk and branches involved in the present invention are described as follows:

[0043] Trunk: The part from above the ground to the first branch is called the trunk or trunk.

[0044] Central trunk: Also called central leading branch (trunk), it is the extension of the trunk and the backbone branch that grows upright in the center of the crown.

[0045] The lower 1 / 3 of the canopy height is the lower part of the canopy, the middle 1 / 3 is the middle part of the canopy, and the upper 1 / 3 is the upper part of the canopy.

[0046] Small main branch: The diameter branched from the central leading branch is less than...

Abstract

The invention discloses a high slender spindle-shaped apple tree form and a trimming method thereof. As a whole, the tree form is of high slender spindle shape. After an apple tree is formed, the crown diameter of the apple tree is small, slender and high. The apple tree is 3.5-4.0m high and the trunk of the apple tree is 0.8-0.9m high. Thirty to fifty spirally arranged small boughs are grown on the central leading trunk of the apple tree. The average length of the small boughs is 1m. The average angle between the central trunk and the small bough is 115 degrees. The top-to-bottom spacing among the small boughs on the same side is 0.25m. The trimming method of the high slender spindle-shaped tree form is simple. Other boughs require no decapitation but branch drawing except that the central trunk requires short-cutting in winters in 1-2 years. Thereby, the trimming method can be popularized in tree forms of simplified trimming and low labor strength.

Description

technical field [0001] The invention belongs to the technical field of apple tree shaping and pruning, and relates to a tall and slender spindle-shaped apple tree shape and a pruning method thereof. Background technique [0002] The orchard with short stock, wide rows and dense planting is the trend and direction of the world's apple development, and an important symbol of the development of the world's modern apple industry. Except for China, the new orchards in the world's major apple producing countries are basically cultivated with short stock and close planting. In many countries, short stock orchards have accounted for more than 80% of the total area of ​​apples. Since the 1980s, my country has promoted close planting with short stock. Now the area of ​​short stock orchards has accounted for 8.1% of the total area of ​​apples in the country, and it is expected to increase to more than 30% in the next 10 years. [0003] Although the development of apple tree shape in m...
