Description

Technical Field

[0001] The present invention relates to a fruit tree grafting knife that does not require learning. The large-sized knife is refined from a stainless steel rectangular tube, and its cutting edge is a rectangular opening-shaped grafting knife; the small-sized knife is refined from a stainless steel rectangular tube, and its cutting edge is a waist-drum-shaped grafting knife, which cuts the rootstock incision and the scion bud skin piece with exactly the same size and shape. Background Art

[0002] 1. The original old-fashioned fruit tree grafting knife: When cutting a rootstock shield-shaped bud skin piece, it takes 4 - 6 cuts to replace the scion bud skin piece, and it is required to align the upper horizontal straight edge of the scion shield-shaped bud piece with the upper horizontal straight edge of the rootstock "T" - shaped incision as precisely as possible. The length of the incision line, the size of the opening area, etc. These cumbersome procedures will bring low efficiency and low survival rate to fruit tree grafting workers.

[0003] 2. Sleeve budding: Its disadvantage is that the diameter of the scion branch is not suitable to select the same thickness, and the cut scion bud skin sleeve cannot fit tightly with the circumference of the rootstock branch, resulting in slow healing, low survival rate, low efficiency, and wasting precious scion bud resources.

[0004] 3. Square bud skin grafting: I once used a double - edged grafting knife with adjustable parallel distance. However, when the worker makes a horizontal cut, it is difficult to control the two parallel cutting edges perpendicular to the longitudinal center line of the scion branch, and when making a vertical cut, it is difficult to keep parallel to the longitudinal center line of the scion branch. The difference between the two cuts results in scion bud pieces and rootstock incisions with different inner adjacent angles. Coupled with the different diameters of the scion branches, it is difficult to fit tightly when the two bud skin pieces are replaced, with low work efficiency, and repeating the above - mentioned defects.

[0005] The above three grafting methods also have a common defect. Because of the thickness of the scion bud skin, there is a certain space left in the bark - folded cortex of the rootstock incision, and the rootstock needs to generate new callus tissue to fill these spaces to complete the healing, which prolongs the healing time of the rootstock wound and reduces the survival rate.

[0006] The old - fashioned single - edged knife is not easy to master, especially for beginners. Moreover, it is easy to cut the finger when not paying attention. Utility Model Content

[0007] The utility model aims at the problems existing in the above - mentioned prior art and adopts a fruit tree grafting knife that does not require learning, which is refined from a high - quality stainless steel rectangular tube with a thickness of 0.3 mm. The size and shape of the cut scion bud piece and the rootstock incision are exactly the same, solving the technical problem of difficult cambium docking. Everyone can use it, with a fast grafting speed and a high survival rate.

[0008] The utility model is realized as follows:

[0009] The large knife has a length × width × height of 90mm × 15mm × 8mm, and can cut branches with a diameter of 10mm - 1000mm. One end is ground into a sharp edge, and the other end is installed with a plastic handle. The cutting edge of the large knife is rectangular. The small knife has a length × width × height of 90mm × 15mm × 5mm - 6mm. The middle width of the two long sides of the cutting edge of the small knife is 6mm, and the widths at both ends are 5mm. The cutting edge of the small knife is waist-shaped. The middle of the cutting edge of the small knife is widened to protect and facilitate the cutting of the scion bud. One end is ground into a sharp edge, and the other end is installed with a plastic handle. The small knife can cut branches with a diameter of 4mm - 20mm.

[0010] Due to the above structure: The utility model adopts rectangular and waist-shaped grafting knives. The sizes and areas of the cuttings of the rootstock and the scion bud pieces cut by this grafting knife are exactly equal. The bud pieces are complete, easy to wrap, convenient and fast. The grafting wounds are in close contact, creating good conditions for wound healing. It has a low cost, is easy to manufacture, and is suitable for industrial production.

[0024] Referring to the attached drawings to illustrate the specific implementation manner of the grafting knife: It is made of high-quality stainless steel rectangular tubes with a thickness of 0.3 mm. The large-sized knife has a length × width × height of 90 mm × 15 mm × 8 mm, and can cut scion branches with a diameter of 10 mm - 1000 mm. One end is ground into a sharp edge, and the other end is installed with a plastic handle. The cutting edge of the large-sized knife is in the shape of a rectangular opening; the small-sized knife has a length × width × height of 90 mm × 15 mm × 5 mm. The middle width of the two long sides of the cutting edge of the small-sized knife is 6 mm, and the width at both ends is 5 mm. The cutting edge of the small-sized knife is in the shape of a waist drum. The middle of the cutting edge of the small-sized knife is widened to protect and facilitate the cutting of the scion bud. One end is ground into a sharp edge, and the other end is installed with a plastic handle. The small-sized knife can cut branches with a diameter of 4 MM - 20 MM.

[0025] During operation, hold the knife in the right hand, aim at the grafting part of the rootstock, apply appropriate force and rotate horizontally around the branch left and right to the corresponding angle, and at the same time shake up and down axially until reaching the xylem. Then use the same method to cut the scion bud and make the scion bud piece loose and semi-connected. First, take out the bark piece of the rootstock, and then take the scion bud piece. Let the growth point of the bud piece face up and quickly move it into the rootstock incision. It is required to complete it within 2 - 3 seconds. During this period, try not to let the wound objects and greases of the two touch. It is known from practice that if the scion bud piece is too thin and the rootstock bark is too thick, the scion bud piece should be taken with a small section of petiole. If the difference is too large, the cut rootstock bark piece should be covered to prevent warping and affecting healing. Pressing with elasticity indicates poor contact. Then tightly wrap the film to prevent rain and keep moisture, and remove the film slightly earlier than conventional grafting.
