Technical Field

[0001] The utility model relates to the technical field of grafting, in particular to a crop grafting support. Background Art

[0002] Grafting is one of the artificial propagation methods of plants, that is, grafting the branches or buds of one plant onto the stem or root of another plant, so that the two parts grow into a complete plant. Grafting can increase the yield of fruit trees. When grafting crops, a crop grafting support is usually used. The grafting support can support the grafted part of the crop, so that the grafting effect of the crop is better.

[0003] For example, a Chinese patent with publication number CN218277914U discloses a crop grafting support, which belongs to the technical field of grafting supports; it includes: a fixing device and a sealing device, wherein the fixing device includes a first fixing sleeve, a second fixing sleeve, and a connecting rod, wherein the first fixing sleeve is an annular structure composed of two semi-rings, and an ear plate is provided on the side wall of the first fixing sleeve, and a fixing bolt is screwed on the ear plate, the first fixing sleeve is placed on the thin grafted branch, and the side wall of the thin grafted branch fits the inner wall of the first fixing sleeve, and the thin grafted branch is fixed to the first fixing sleeve by using the fixing bolt, the second fixing sleeve is an annular structure composed of two semi-rings, and an ear plate is provided on the side wall of the second fixing sleeve, and a fixing bolt is screwed on the ear plate, and a protective cover is used to wrap the grafting interface, which can keep warm and moist, and prevent the invasion of external pathogens, so that the grafting can heal better, and can fix the two grafted branches to prevent deviation or falling off.

[0004] The patent fixes the two branches at the grafting site. However, after the grafting is successful, the grafted branches sometimes need to be supported to prevent them from bending too much and causing the grafting site to break. The grafting support described in the patent cannot support the grafted branches after the grafting is completed. Therefore, the planters need to install an additional support frame to prevent the grafted branches from bending, which increases the planting cost. Utility Model Content
