Background technique

As a multi-functional and characteristic native plant, the demand for giant Bauhinia is increasing year by year with the development of the application market. However, due to the special dormancy of giant Bauhinia seeds, the natural germination power is poor, the seedling breeding efficiency is low, and it is difficult to ensure the seedlings themselves. The excellent characteristics of seedlings lead to uneven quality of seedlings; although cuttings can make up for the shortcomings of seedlings themselves, they are slow in rooting, single-colored seedlings, and long-term cultivation cycle, which makes it difficult to meet the market demand for high-quality seedlings of Giant Bauhinia in a short period of time. Based on the above shortcomings in seedling cultivation, the grafting and seedling raising technology has effectively improved the cultivation efficiency of high-quality giant Bauhinia seedlings, and improved the quality and ornamental effect of seedlings.

Grafting, that is, grafting the branches or buds of one plant to the stem or root of another plant, so that the two parts that are joined together grow into a complete plant, which requires a special cutting tool, which can effectively cut Cutting plant tissue can also minimize damage to plant tissue. At present, the functions of the commonly used grafting tools for grafting are relatively simple. Different tools are required for pruning, cutting, and trimming of scions. The work procedure is relatively complicated, and multiple grafting aids must be carried. It is very inconvenient to carry out the work and greatly reduces the work efficiency. So there is room for improvement.
