Reshaping trimming method for inverted umbrella shape of persimmon tree

Abstract

The invention discloses a reshaping trimming method for an inverted umbrella shape of a persimmon tree. The method specifically comprises after planting a seedling in spring, determining the stem height to be 40-50 cm high from the ground, generally speaking, 3-5 new shoots can grow from the cut; selecting one vertical and robust shoot from the top end to cultivate a central stem; selecting three new shoots in different directions under the central stem new shoot to cultivate principal branches, wherein the directions of the principal branches should obliquely face toward the line space with horizontal included angles of 120 degrees; during winner trimming, truncating the extended branch of the stem at the position of the 40-50 cm plump sprout to maintain the dominance of the central leading stem and truncating the principle stems at the position of 50 cm; after the plant sprouts in the next spring, continuously selecting a vertical and robust new shoot at the top of the central stem as an extended branch to maintain the dominance of the central stem and twisting rival shoots under the central stem. According to the reshaping trimming method for the inverted umbrella shape of the persimmon tree, the inverted umbrella-shaped persimmon tree is rapid in shaping, good in light illumination, early in blossoming and fruit bearing, high in yield and fruit quality and capable of facilitating manual or mechanical operation and management.

Description

technical field [0001] The invention relates to a method for shaping and pruning a fruit tree, in particular to a method for shaping and pruning a persimmon tree in an inverted umbrella shape. Background technique [0002] Persimmon trees have strong stems, vigorous growth, and obvious advantages at the top. In the past, it has been cultivated with sparse planting and large crowns, and the results are late and the yield is low. There are some common problems in the pruning of persimmon trees: some people mistakenly believe that persimmon trees do not need to be pruned, but let them grow freely; The angle of the main branch is not open, the ventilation and light transmission are poor, the inner chamber is empty, the fruiting part moves outward, the time of fruit setting is late, the high yield is late, the yield is low and unstable, and there are few high-quality fruits. The traditional pruning method is often used because of its strong dryness, which makes it inconvenient ...

AI Technical Summary

Problems solved by technology

There are some common problems in the plastic pruning of persimmon trees: Some people mistakenly believe that persimmon trees do not need to be pruned, and they are left to grow. The angle of the main branch is not open, the ventilation and light transmission are poor, the inner chamber is empty, the fruiting part moves outward, the time of fruit setting is late, the high yield is late, the yield is low and unstable, and there are few high-quality fruits

The traditional pruning method is often used because of its strong dryness, resulting in high tree shape and inconvenient picking.
