Multi-edge grafting cutter for fruit tree grafting

Abstract

The invention discloses a multi-edge grafting cutter for fruit tree grafting. The cutter comprises a cutter body, a cutter shell and a cutter body fixing base, a saw-shaped cutter edge, an inward-concave arc cutter edge, a straight cutter edge and an outward-convex arc cutter edge are arranged at the upper end of the cutter body, and the right end of the cutter body is fixed to a cutter body fixing plate through screws; a limit pipe is arranged on the cutter body fixing plate, a cutter shell inner cavity is formed in the cutter shell, and a sliding groove is formed in the front end face of thecutter shell; limit holes distributed in an array are formed in the bottom of the cutter shell inner cavity in the inner side of the sliding groove, a limit rod is arranged in the sliding groove, andthe cutter body fixing base is fixed to the right side of the cutter shell. According to the multi-edge grafting cutter for fruit tree grafting, the four kinds of cutter edges can be applied to different types of fruit trees the probability of damaging the woodiness at the same time of peeling bark can be effectively lowered, and a large number of single cutter bodies with monotonous functions are prevented from being carried; the cutter body can be stored in the cutter shell, people can be prevented from being accidentally injured, the cutter body can be replaced, the grafting quality is guaranteed, the cutter body fixing base can fix other types of cutters, and the grafting fluency is improved.

Description

technical field [0001] The invention relates to a grafting knife, in particular to a multi-edge grafting knife for fruit tree grafting. Background technique [0002] Grafting is one of the methods of artificial propagation of plants. That is to graft the branches or buds of one plant onto the stem or root of another plant, so that the two parts connected together grow into a complete plant. Grafting methods are divided into branch grafting and bud grafting. Grafting is carried out by utilizing the ability of plants to heal after injury. Grafting is a type of vegetative reproduction in asexual reproduction. When grafting, the scion should be closely combined with the cambium of the rootstock to ensure the survival of the scion. The connected branches or buds are called scions; the grafted plant bodies are called rootstocks or platform wood. Generally select the seedling of tool 2 to 4 buds during scion, become the upper part or the top of plant body after grafting, roots...

AI Technical Summary

Problems solved by technology

[0003] At present, many kinds of knives are needed in the operation of fruit tree grafting. However, the commonly used fruit tree grafting knives are usually composed of a handle and a knife head. On different types of fruit trees, the probability of damaging the wood while peeling the bark increases, which affects the survival rate. At the same time, the knife body cannot be replaced, and the quality of grafting will be affected after long-term use causes wear and tear.
