Technical Field

[0001] The utility model relates to the technical field of pruning devices, in particular to an adjustable apple planting pruning device. Background Art

[0002] Apple, a deciduous tree in the genus Malus in the Rosaceae family, has a tall stem and short, thick, cylindrical branches. Its leaves are oval, smooth, with serrated edges and thick petioles. Its flowers are small, umbrella-shaped, pale pink, and covered with fuzz. Its fruit is large, oblate, and has a short, thick stalk. It blooms in May and fruiting occurs from July to October. The name "apple" was first mentioned in Wang Shimao's "Xuepu Yushu" (Study of Gardening) in the Ming Dynasty. It refers to the northern "Styraciflua fruit," a variation of the "Huahong" variety.

[0003] Apple tree pruning is the process of cutting or trimming the branches of the apple tree. Pruning allows the branches and leaves of the apple tree to be reasonably distributed, regulates the proportion of growth and fruiting, and branch composition, and balances the growth potential between groups of plants. It can advance the fruiting age, improve the light conditions of the tree, improve the nutrition of the tree, promote the healthy growth of the tree, improve the resistance of the apple tree to stress, increase fruit yield and increase commercial value.

[0004] When pruning deep branches, the length of the pruning device can be adjusted, allowing the device to prune apple branches from the outside. However, the length adjustment device is usually adjusted by telescoping two rods. When the device is retracted, it still has a certain length, which is inconvenient to use. To solve this problem, we propose an adjustable apple planting pruning device to solve the above problem. Utility Model Content
