Reshaping trimming method for high-illumination-efficiency shape of close-planting persimmon tree

Abstract

The invention discloses a reshaping trimming method for a high-illumination-efficiency shape (one central stem with two branches) of a close-planting persimmon tree. The method specifically comprises after a plant is planted, determining the stem height to be 40-50 centimeters from the root; when the new shoots grow up to be 20 centimeters long, selecting one vertical and robust new shoot to cultivate a central stem; selecting two staggered, opposite, uniformly-growing new shoots as principal branches, which are extends towards the line space, and removing other long branches to form a horizontal shape to control the growth of the principal branches and prompt maturity of branches and flower buds for early fruit bearing, taking no action on other short branches; during winter trimming, trimming the central stem with a length of 40-50 centimeters retained, truncating the principle branches at the position of about 50 centimeters and taking no action on other branches; performing reshaping according to the method above in the next year and the third year to fundamentally completing the reshaping task. The close-planting persimmon tree with the high-illumination-efficiency shape of one central stem with two branches 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 fruit trees, in particular to a method for shaping and pruning persimmon trees with densely planted and high-light-efficiency tree shapes. 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 don’t need to be pruned and let them grow freely; As a result, the tree shape of many persimmon gardens is relatively disordered, with many large branches and few small branches on the tree. Steady, with few high-quality fruits. The traditional pruning method is often used because of its strong dryness, which makes it inconvenient to pick because of the high tree shape. [0003] In terms of production, th...

Problems solved by technology

There are some common problems in plastic pruning of persimmon trees: some people mistakenly believe that persimmon trees don’t need to be pruned and let them grow freely;

As a result, the tree shape of many persimmon gardens is relatively disordered, with many large branches and few small branches on the tree. Stable, less high-quality fruit

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