Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of forest grafting, specifically to an economic forest grafting fixing device. BACKGROUND

[0002] Grafting is a kind of propagation method that the bud or branch of one plant is connected to another plant to grow into a complete plant. The connected bud or branch is called scion, and the connected plant is called stock. The key to successful grafting is to tightly combine the cambium of scion and stock.

[0003] The patent with publication number CN210959548U discloses a grafting fixing support, which comprises a fixing assembly and a connecting assembly. The fixing assembly comprises an upper fixing belt, an upper fixing bolt, an upper fixing block, a lower fixing block, a lower fixing belt and a lower fixing bolt. The upper fixing belt is connected to the upper fixing block. The device can firmly fix two plants. The new grafting fixing support is not easy to deform, and greatly improves the success rate of grafting.

[0004] However, the length of the connecting rod connecting the lower fixing belt and the upper fixing belt is fixed, while the grafting positions of plants in actual life are different, which leads to an increase in the use cost of the grafting device if the length of the connecting rod is manufactured according to the grafting position of the plant. On the contrary, the fixed length of the connecting rod cannot meet the fixation of different grafting plants. Therefore, an economic forest grafting fixing device is proposed to solve the problem that the existing fixing device cannot adjust the fixing position according to the grafting position of the plant.
