Big cherry tree shaping, trimming and managing technique

Abstract

The invention discloses a big cherry tree shaping, trimming and managing technique. A big cherry tree which is high in wind resistance, early in fruiting, big in fruit, high in yield and easy to manage can be cultivated through a series of techniques of seedling selection, field planting, tree form cultivating, trimming, fertilizing and the like.

Description

technical field [0001] The invention relates to a technique for shaping and pruning management of large cherry trees. Background technique [0002] At present, most of the early high-yield tree shapes of big cherries promoted by various big cherry producing areas and various big cherry research units in the country are free spindle shapes, and the following two methods are generally used for shaping: [0003] method one: [0004] 1. Set the height of the trunk to 80-100 cm. From late July to late August, pull the angle of the main branch to 80-90 degrees; twist the tip or re-pick the upright branch. [0005] 2. Carve buds before budding in the spring of the second year: carve a bud every 10-15 cm on the main trunk according to the direction of branching, 6-7. , all the buds on both sides and the back are engraved until they are 30 cm from the tip. After the lower part of the central dry branch germinates, cut the central dry branch about 1 meter up from the fixed trunk. ...

Problems solved by technology

[0013] (1) Spindle-shaped horizontal branches, because the lower branches are too close to the ground, it is inconvenient to manage

[0014] (2) Horizontal pulling of branches mainly relies on the upper branches on the back to bear fruit (the branches on both sides also grow upwards to become upper branches on the back). vicious circle

[0015] (3) Spindle-shaped horizontal branches mainly bear fruit on the back branches, and after topping, mainly produce fruit from axillary buds, and each fruit branch has a high density an
