Description

Technical Field

[0001] The invention belongs to the technical field of branch pruning devices, and in particular relates to a blueberry branch pruning device. Background Art

[0002] Blueberry is a perennial shrub of the genus Vaccinium in the Ericaceae family. It has distinct characteristics: short plants, thin branches, leathery or papery leaves, fresh flowers, sweet and sour juicy fruits, dark blue or violet in color, and prefers a warm, humid and sunny environment and requires acidic soil rich in organic matter. Pruning branches can improve ventilation and light transmission, reduce pests and diseases, enhance resistance, promote the growth of new branches, improve yield quality, control tree shape, facilitate management and picking, and optimize nutrient distribution to improve the taste of the fruit.
