Fruit tree pruning method capable of improving yield and quality of fruits

Abstract

The invention discloses a fruit tree pruning method capable of improving the yield and the quality of fruits. The method comprises the following steps: carving buds for the first time, namely, carving buds on positions, more than 90cm high, of a main stem base part before budding; changing axes completely, namely, completely shearing off main branches born in the first year at one time, leaving 2mm crops for rotation at base openings; carving buds for the second time, namely, carving buds on the crops for rotation before budding; slowly placing; reserving branch groups bearing fruits; shearing off unnecessary branches after axis changing, and using 25-30 distances between the branches as fruit bearing branch groups; balancing tree vigor; conducting axis changing processing on vigorous branches of the bearing branch groups. The method has the advantages that fruit trees supply needed nutrition for flower buds in a centralized mode after axis changing processing, and vigorous branches at the top are reduced, so that nutrition waste is effectively avoided, and a large amount of manpower for trimming branches is saved; tree body nutrition is effectively transmitted to the positions where flower buds form, so that the formation of the flower buds are greatly promoted, the output of fruit products is improved by 1.5 times, and economic benefits are considerable; the tree body is good in ventilation performance and light transmission performance so as to be favorable to operation such as manual bagging and medication. Moreover, fruits are good in coloring and are regular in shape.

Description

technical field [0001] The invention relates to a fruit tree pruning method, in particular to a fruit tree pruning method capable of improving fruit yield and quality, and belongs to the field of fruit tree cultivation. Background technique [0002] Existing fruit tree pruning method, refer to figure 1 , Usually, the first year: set the stem; the second year: natural growth; the third year: branching treatment; the fourth year: girdling the fixed trunk; the fifth year: training the central leadership. [0003] After many years of practice, it is found that the existing fruit tree pruning method has the following problems: [0004] 1. The fixed trunk causes nutrient planting control. The main branches of the first layer of branches in the 20cm trunk are excessively concentrated, which is not conducive to ventilation and light transmission, and is also not conducive to manual bagging and medication; [0005] 2. The main branch depends on pulling the branches, which weakens t...

AI Technical Summary

Problems solved by technology

[0004] 1. The fixed trunk causes nutrient planting control. The main branches of the first layer of branches in the 20cm trunk are excessively concentrated, which is not conducive to ventilation and light transmission, and is also not conducive to manual bagging and medication;

[0005] 2. The main branch depends on the branch, which weakens the tree vigor, which not only wastes manpower, but also leads to the increase of upright branches due to excessive nutrition, and the top advantage is obvious, resulting in a waste of nutrition

[0006] 3. There are too many vigorous branches, and the nutrition of ...
