TECHNICAL FIELD
[0001] The utility model relates to the technical field of scion cutting, especially to a fine scion cutting for eight-angle grafting. BACKGROUND
[0002] The fine scion for eight-angle grafting refers to the branch of the eight-angle tree of the excellent variety, which is used for grafting propagation. The selection of the fine scion is crucial, which directly affects the survival rate and growth performance of subsequent grafting. By selecting the variety with strong disease resistance, high yield and good adaptability, the quality and production efficiency of the plant can be improved. The scion cutting plays a core role in the grafting process, and correct cutting can ensure the quality of the scion, reduce the spread of diseases, and at the same time ensure the close docking of the grafting part, and improve the success rate of grafting. Therefore, accurate scion cutting is not only a necessary step to improve the propagation efficiency of eight-angle, but also ensures the healthy growth and high yield of the plant after grafting.
[0003] The traditional fine scion cutting method for eight-angle grafting usually includes selecting healthy, disease-free and excellent variety branches, which are usually taken from 2-5 year old trees. The scion cutting should be carried out in spring or autumn, and the semi-lignified branches with a length of 10-15 cm and 2-3 full bud points are cut. The cut surface should be smooth and avoid burrs or serrations. To avoid infection, the scion needs to be disinfected, such as soaking in potassium permanganate or carbendazim solution. The cut scion should be kept moist, usually wrapped with a wet cloth or stored in a cold place to maintain its activity and moisture. This method is simple and direct, but it depends on manual operation, which is easily affected by the technical level of the operator and environmental factors.
[0004] The traditional fine scion cutting for eight-angle grafting usually uses fixed blades or cutting heads, which are difficult to disassemble or replace, so it is difficult to quickly replace the cutting tool or cutting head according to the needs, which limits the versatility and flexibility of the tool. At the same time, if the cutting head is damaged, cracked or rusty, it will directly affect the quality of the scion and the success rate of grafting, which is easy to cause damage to the scion, disease infection or poor healing of the grafting part.
