Pepper tree fusiform shape pruning method

Abstract

The invention provides a fusiform dressing method for trimming pricklyash peel main stems which comprises two stages of sapling stereotyped culturing and control pruning during fruit blossom stage, wherein during the pruning the upper portions of the main stems are subject to principal branch facilitation, lower bud wiping, drawing and stretching principal branch, equalized core extraction, retracting and shorting, old branch regenerating, main stem mastheading and suitable condensed planting.

Description

Technical field [0001] The method for shaping and pruning the spindle shape of the main rod of Chinese prickly ash according to the invention relates to the pruning and pruning technology of forest fruit trees, in particular to the pruning and pruning technology of prickly ash. Background technique [0002] Zanthoxylum bungeanum belongs to the Rutaceae plant, which is a small deciduous tree or shrub with a height of 3-7 meters. From the root to the treetop, it can be divided into four parts: rhizome, main pole, main branch and side branch. If the Zanthoxylum bungeanum tree is left to grow naturally without pruning, the canopy will be closed, the branches will be disordered, the vegetative growth will be out of control, and the ventilation and light transmission in the canopy will be poor. The vigor of the tree gradually weakened, the yield decreased, and the quality decreased. Reasonable pruning of Zanthoxylum bungeanum can improve the use of sunlight, regulate the balance ...

AI Technical Summary

Problems solved by technology

At present, the pruning methods of prickly pear are clump shape, natural happy shape, multi-main branch happy shape and horizontal branch fan shape. Due to the traditional pruning method of prickly ash, it is cut at the base of the main stem in the young tree stage. 3-5 first-level main branches. After the main branches grow taller, select multiple second-level main branches or side branches on each first-level main branch. Multiple main branches grow in clusters at the base of the pepper rhizome. Since the main branches grow relatively Standing upright causes competition for light, water, and nutrients, and each forms a small crown. Although the crown is pruned, the crown is still uncontrollable. When the fruit is in full bloom, the canopy will still be closed, the branches will be disordered, the vegetative growth will be out of control, and the reproductive growth will decline year by year. Insufficient use of light and effective three-dimensional space affects the yield and quality of peppercorns, and is inconvenient for field management and pepper picking, which increases production costs and shortens the effective economic period of the tree.
