Description

Bud carving knife for fruit trees

Technical Field

The utility model relates to the technical field of bud carving knives, in particular to a fruit tree bud carving knife.

Background

The bud carving of the fruit tree is an important means for managing the fruit tree in spring, is commonly used for shaping young fruit trees, achieves the aims of balancing the tree vigor and regulating the growth of branches by changing the nutrition flow direction in the fruit tree, and particularly can be used for directional branching, and the accurate bud carving is an important technical measure for managing the fruit tree.

The carved bud is generally carved on the position 3-5 mm above or below the bud eye or bud body of the fruit tree branch, and a tool is used for cutting the cortex sieve tube to the xylem. By bud carving, a good tree body structure can be built, high-quality branches are formed by concentrating nutrition, fruiting branch groups are cultured, the tree body structure is corrected, tree vigor is balanced, and early flowering and early fruiting are achieved.

Most bud carving tools currently in use are small blades, scissors and small saw blades, which are inefficient, cumbersome to use, and can cause excessive soreness to the local finger during long-term operation.
