A kind of shaping and pruning method of inverted umbrella shape of big cherry tree

Abstract

The invention discloses a method for inverted umbrella-shaped tree form shaping pruning of a large cherry tree. Pruning modes in four years are adopted for the method. The method comprises the steps of controlling growth vigor of the large cherry tree on a first year, promoting branch mature and bud satiation, and promoting early bearing of the large cherry tree; on a second year, continuing selecting a vertical robust shoot to serve as an extending shoot at the top end of a center trunk after sprouting, keeping the growing dominant position of the center trunk; on a third year, performing shaping according to the taken measures, and basically finishing shaping tasks; on a fourth year, enabling the tree to fruit massively, enabling the growth of shoots to be slow down, enabling the tree vigor be basically stable, and starting to enter a high-yield and stable-yield period. The inverted umbrella-shaped tree form of the large cherry tree is formed quickly, illumination is good, the large cherry tree blossoms and fruits early and is high in yield and good in quality, and manual or mechanical operation management is facilitated.

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 large cherry tree in an inverted umbrella shape. Background technique [0002] Cherry is the abbreviation of European sweet cherry, which belongs to the deciduous tree fruit tree of Rosaceae. Large cherry saplings grow vigorously, with obvious top dominance, late fruiting, long production period and slow effect. At present, the most widely used tree shapes of large cherry trees in my country mainly include free spindle shape, evacuated layered shape, and cluster shape. Especially the varieties such as Red Lantern, Italian Zaohong, Meizao, and Labins adopt the traditional free spindle shape, often because of their strong dryness, the main branches (large-scale fruiting branch groups) are empty, and the tree shape is tall so that It is inconvenient to pick; if the traditional trunk layered and clump-shaped are used, it is easy to ...
