Fruit tree shaping and trimming method

Abstract

The present invention discloses a form pruning method of fruit tree. Said method includes the following steps: (1), in first year, selecting and setting first layer of 46-6 main branches which are not overlapped for central trunk, making included angle between main branch and central trunk be greater than 90 deg.; (2), in second year, defining 3-5 layers of main branches over first layer of main branches, every layer has 1-3 mutually non-overlapped main branches, the upper layer of main branches and the lower layer of main branches are not overlapped mutually, making all the included angles between main branches and central trunk be greatly than 90 deg.; and (3), in third year-fifth year, pruning to make the tree height be controlled within 3 meters, setting 4-6 layers of 7-21 main branches, making every included angle between every main branch and central trunk be greater than 90 deg.

Description

technical field

[0001] The invention relates to a method for shaping and pruning fruit trees. Background technique

[0002] Fruit tree pruning is mainly to cultivate a solid crown skeleton, build a reasonable individual and group structure, coordinate the aboveground and underground parts of the fruit tree, the harmonious coexistence of branches and branches in the tree, the balance and harmony of vegetative growth and reproductive growth, and the aging and renewal of branch groups. relationship, thereby helping fruit trees to achieve the goals of premature birth, high yield, stable yield, high quality, longevity and ease of management. Improper pruning or pruning errors, tree shape not suitable for the growth and fruiting habits of fruit trees, poor tree structure, poor ventilation and light transmission of the canopy, etc., are important reasons for the low yield of fruit trees. A good tree structure is the basis for high yield of fruit trees. At present, the pruning tech...
