Description

Technical Field

[0001] The utility model belongs to the technical field of winter jujube cultivation, and particularly relates to a grafting auxiliary device for dwarfing cultivation of winter jujubes. Background Technique

[0002] Grafting is one of the artificial propagation methods of plants, that is, a branch or bud of one plant is grafted onto the stem or root of another plant, so that the two parts joined together grow into a complete plant. Grafting is carried out by utilizing the function of plants to callus after being injured.

[0003] When grafting jujube trees, the cleft grafting method is a commonly used method, but improper operation will cause some problems. Specifically, if the scion is cut too thick and not enough blank part is left, when the grafted tree encounters extreme weather such as strong wind, due to the insufficient tight connection between the scion and the rootstock, it is very easy to be broken by the strong wind. This is because cutting too thick will result in a large gap between the scion and the rootstock, reducing the contact area between them, thus reducing the stability of the connection. Moreover, the winter jujube scion is generally short, usually with a single bud, and the length is about 4-5 cm. This short length makes the manual cutting of the scion more delicate, but manual cutting is not easy to control, and uneven cutting is likely to affect the cutting quality, thereby affecting the survival rate of grafting and the quality of subsequent fruits.

[0004] Therefore, when grafting jujube trees, attention should be paid to mastering the correct scion cutting technique to ensure that the scion is cut neither too thick nor too thin, and at the same time leave an appropriate blank part to improve the success rate of grafting and the wind resistance of the tree. Using a device for cutting the scion can reduce the labor intensity of fruit tree technicians, avoid the harm to fingers caused by long-term manual cutting, and also reduce the cutting error caused by human factors.

[0005] In addition, the humidity of the interface is a factor that is easily overlooked in grafting. Insufficient humidity of the interface has a great impact on the survival rate of grafted seedlings. Timely moisturizing of grafted seedlings can reduce water evaporation, extend the grafting time, improve the survival rate, etc., and is an important technical point for improving the planting efficiency and fruit quality of winter jujubes.

[0006] At present, the existing dwarfing grafting auxiliary device for winter jujubes only considers the cutting treatment of one side of the scion, without considering the cutting of both sides of the scion. Moreover, the existing dwarfing cultivation grafting auxiliary device for winter jujubes lacks the moisturizing measure for the scion after cutting. Once the moisturizing measure fails to keep up in time, the survival rate of grafting will be reduced.

[0007] Therefore, it is necessary to provide a grafting auxiliary device for dwarfing cultivation of winter jujubes to overcome the problems existing in the existing device. Content of the Utility Model
