Embodiment Construction

[0012] A kind of shaping and pruning method of three main branches natural happy-shaped peach trees of this example includes: setting the stem at a height of 50-60cm in the year of planting, selecting three main branches, and cutting the three main branches in winter in the first year. Cut off and keep 40-50cm; in the second year of winter pruning, select 5-6 well-developed and open-angled new shoots from the side branches of each main branch, and cut off the rest from the base. When the side branches reach 25-30cm, Then choose and stay 3 side branches with vigorous growth and uniform thickness of branches as the fruiting branches; in the third year spring, the more prosperous branches on the side branches are topped, and the branches are pulled in summer, and the main shoots are topped in autumn. Cut off the back branches, competing branches, and new side branches on the branches, and further increase the angle of pulling branches in the fourth year.

Abstract

The invention discloses a method for shaping and pruning an open center-shaped peach tree with three main branches. The method comprises the steps as follows: in the year when the peach tree is planted, the trunk is fixed at the height of 50-60 cm, three main branches are selected, and in the first winter, the three main branches are truncated and are kept for a 40-50 cm in length; in the second winter, 5-6 well developed shoots with wide angle are reserved and selected from lateral branches of each main branch, the rest of shoots are cut off from the base part, and when the lateral branches grow being 25-30 cm long, 3 exuberant lateral branches with twigs being uniform in thickness are reserved and selected as bearing branches; and in the third spring, relatively exuberant twigs on the lateral branches are subjected to top removal, the twigs are drawn in summer, the leading shoots are subjected to top removal in autumn, back branches, competitive branches and newly sprouting lateral branches are cut off from the main branches in winter, and in the fourth year, the branch drawing angle is further enlarged. According to the invention, on the basis that the three main branches form an open center shape, by the manage mode of supplementing summer pruning with winter pruning, the three outline of the peach tree is more reasonable, and bearing quality and quantity are increased.

Description

technical field [0001] The invention relates to the field of fruit tree planting and management, in particular to a method for shaping and pruning a three-main-branch natural happy-shaped peach tree. Background technique [0002] Peach trees are Rosaceae deciduous trees with black bark. They are common fruit trees and ornamental flowers and trees. Peach trees are light-loving plants with strong germination and branching ability. The buds of peach trees are precocious. Therefore, in areas with long growth periods and suitable environmental conditions, 3 to 4 secondary shoots can be produced within a year, or even more, forming multiple branches and multiple growths. This provides favorable conditions for accelerated shaping and early results, thus providing conditions for plastic pruning. [0003] At present, the high-yield peach tree shapes that are widely used in production mainly include: cup shape, natural happy shape, trunk shape, Y shape, etc. Among them, there are 3...
