Description

TECHNICAL FIELD

[0001] The utility model relates to forestry planting field, concretely is a branch pruning device for forestry planting. BACKGROUND

[0002] In forestry planting, there are mainly the following reasons for pruning branches:

[0003] Adjusting tree vigor: pruning can remove part of the branches, reduce the amount of leaves and branches of the tree, and thus reduce the transpiration of the tree; this enables the tree to better allocate resources under the condition of limited water and nutrients, and use more energy for root growth and trunk thickening, thereby enhancing the overall growth vigor of the tree; for trees that grow too vigorously, appropriate pruning can control their growth rate, making their growth more balanced and stable; for example, if some fast-growing tree species do not undergo pruning in the early growth stage, they may exhibit excessive growth, resulting in slender trunks and sparse crowns, affecting the stability and wind resistance of the tree; through pruning, the tree branches can be made more reasonable, the crown can be made more full, and the quality of the tree can be improved;

[0004] Improving light and ventilation conditions: in forestry planting, trees are often dense, which can easily cause mutual shading of the crowns, affecting light and ventilation; pruning can remove dense branches, crossing branches and overlapping branches, allowing sunlight to fully penetrate the interior of the crown and the lower leaves, promoting photosynthesis; good light conditions help the tree to synthesize more nutrients, improving growth rate and quality;

[0005] When pruning forestry trees, pruning devices are needed to prune the trees; however, the existing pruning devices still have deficiencies in use, as shown in the specification: Figure 1 The pruning device causes hand abrasion after a period of use, reducing the comfort of the operator, and causing harm to the hands of the operator during long-term work.
