technical field

The invention relates to a grafting device, in particular to a tomato grafting device.

Background technique

Tomatoes, also known as tomatoes, are herbaceous plants belonging to the order of Tubular Flowers, Solanaceae, and Tomato. Special flavor; it has the functions of losing weight, eliminating fatigue, increasing appetite, improving protein digestion, and reducing stomach bloating and food accumulation. It is a vegetable that consumers love very much. Grafting of tomato trees is a new technology that has been promoted in recent years. There are many existing tomato tree grafting methods, such as leaning, plugging, splitting, oblique sticking, budding and other methods. During grafting, a grafting device will be used for auxiliary grafting, thereby improving the survival rate of the tomato tree after grafting.

In the prior art, the existing grafting device is relatively simple. The mother plant and the graft are wrapped and fixed with plastic cloth, or the grafted part is directly clamped with a clip to fix and protect the grafted part.

However, whether it is fixed by plastic sheeting or by clips, the grafting site will not be fixed firmly, and it is easily affected by external forces, resulting in the separation of the mother plant and the grafted graft, resulting in poor survival rate of the grafted tomato tree. High, waste of manpower and material resources.
