Bud grafting knife for grafting forest fruit tree seedlings

Abstract

The utility model provides a special cutter for bud grafting cutting of forest fruit tree nursery stock, which comprises a cutter head, a cutter neck and a cutter handle, the cutter head has a convex arc shape, so that the cutter head has a cutting operation function, the cutter head is short and small, the operation is flexible, the use is more convenient, and the problems that the existing bud grafting cutter is uncomfortable in clamping and inflexible in operation after being used for a long time are solved. The method is applied to industrial production using the shield-shaped bud grafting method, the grafting speed can be further increased while the bud grafting survival rate and the grafting bud utilization rate are increased, and therefore industrial popularization and application of the shield-shaped bud grafting method in forest fruit nursery stock grafting production are promoted, and the industrial production efficiency of forest fruit nursery stock bud grafting is improved.

Description

Technical Field

[0001] This utility model relates to a grafting tool for forest and fruit tree seedlings, and particularly to a bud grafting knife for grafting forest and fruit tree seedlings. Background Technology

[0002] Whether self-pollinating or cross-pollinating, forest and fruit trees undergo chromosome recombination to produce heterozygous seeds. Therefore, seed propagation results in significant differentiation, and the resulting trees often fail to retain their original superior qualities, such as rapid growth, high quality, high yield, or specific resistance. If propagation through cuttings or other asexual methods is difficult, grafting is the only way to maintain the original qualities. This involves taking branches or buds as scions for grafting. Therefore, many superior forest and fruit tree varieties are propagated using grafting.

[0003] Grafting methods for forest and fruit tree seedlings mainly include branch grafting, bud grafting, and root grafting. Compared with branch and root grafting, conventional bud grafting has a higher survival rate and rootstock / scion utilization rate. However, existing bud grafting tools generally suffer from difficulties in gripping the tool, thus limiting the grafting speed and affecting grafting efficiency. Therefore, developing a specialized cutting tool for bud grafting of forest and fruit tree seedlings is of great practical significance for further improving the industrial production efficiency of bud grafting of forest and fruit tree seedlings. Summary of the Invention

[0004] The purpose of this utility model is to provide a special cutting tool for bud grafting of forest and fruit tree seedlings, so as to improve the production efficiency of bud grafting of forest and fruit tree seedlings.

[0005] A budding knife for grafting forest and fruit tree seedlings, as shown in Figure 1, includes: a blade head 1, a blade neck 2, and a handle 3.

[0006] The blade has a sharp edge located at the front end of the budding knife. The sharp edge is a slightly convex arc-shaped blade, and the slightly convex arc-shaped blade forms a certain angle A with the handle 3, preferably the angle A is 30°.

[0007] The blade neck 2 is located between the blade head 1 and the handle 3. The blade neck gradually narrows compared to the blade head and handle to improve the firmness of the operator's thumb and forefinger gripping the blade and effectively withstand and transmit the upward pushing force applied by the operator's thumb.

[0008] The handle 3 is located at the tail of the budding knife, has a length suitable for hand gripping, and is wrapped with medical tape to improve the operator's gripping stability and comfort.

[0009] The grafting knife used for grafting forest and fruit tree seedlings is made of tool steel with high hardness and a certain degree of toughness. Attached Figure Description

[0011] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0012] A budding knife for grafting forest and fruit tree seedlings, as shown in Figure 1, includes: a blade head 1, a blade neck 2, and a handle 3, with an overall length of 14cm; wherein: the blade head 1 is 3.5cm long, the convex arc-shaped cutting edge is 3.8-4.2cm long and 0-1.5cm wide, the angle A between the slightly convex arc-shaped cutting edge of the blade head 1 and the handle 3 is 30°, the blade neck 2 is 3.0cm long and 1.1-1.5cm wide, the handle 3 is 7.5cm long, and the blade body is 1.5cm wide.

[0013] First, the bud patch is cut. When cutting the bud patch, generally hold the branch with your left hand and the utility model knife with your right hand. First, make a horizontal cut 0.8cm above the bud, reaching the xylem. Then, use the slightly convex, rounded blade to cut 1.0cm below the bud, cutting upwards from bottom to top, also reaching the xylem, until you reach the horizontal cut. This will create a shield-shaped bud patch that is wider at the top and narrower at the bottom. Next, the rootstock is cut. At the intended bud location on the rootstock, make a horizontal cut with the budding knife. Then, make a vertical cut about 2.5cm long from the center of the horizontal cut, forming a "T" shaped incision. Use the tip of the knife to pry open the bark and insert the cut bud patch into the "T" shaped incision, ensuring that the cross-section of the bud patch is tightly connected to the bark of the rootstock. Cover it with the bark of the rootstock and then bind it with a plastic strip.
