A kind of Chinese toon bud graft propagation method

Abstract

The invention relates to a cedrela sinensis budding and propagating method. The method comprises the followings: selecting annual tree seedlings of cedrela sinensis, which grow strongly and have a ground diameter of 1.0 to 1.2 cm, as rootstocks, and adopting annual branches which are robust, in full buds and free of plant diseases and insect pests from a cedrela sinensis seed tree for budding, so as to realize cedrela sinensis micropropagation. The budding specifically comprises the followings: selecting strong buds in the middles of the branches for scion, transversely cutting in places which is above the buds and is 0.5 cm far away from the buds, and then transversely cutting in places which are below the buds and are 0.5cm far away from the buds, wherein each bud piece requires a part of wood part to be carried, the thickness is 2 to 3 mm, and the lengths of the cutting surfaces of the bud pieces are 1.0 to 1.5 cm; selecting northeast surfaces of the rootstocks, cutting off skin blocks in positions 5 cm far away from the ground, (the rootstock cutting method is the same as the scion), then taking down the cut skin blocks, quickly adhering the bud pieces onto the cutting surfaces, enabling the lower ends of the bud pieces to be aligned with the lower cuts of cut surfaces, and then using ropes for tightening. The method provided by the invention has the characteristics of simple operation and high ratio of grafting, the cultivated seedling is high, the diameter growth is fast, and a good foundation is established for storing and using cedrela sinensis fine breeds in future.

Description

technical field [0001] The invention relates to the field of plant seedling breeding, in particular to a Chinese toon budding propagation method. Background technique [0002] Chinese toon is an excellent material, edible and landscaping tree species in my country. It grows rapidly, has strong resistance to diseases and insect pests, strong adaptability, good material, beautiful texture, and aromatic smell. It is known as "Chinese mahogany". It is a high-quality furniture material; in 2012, Chinese toon was included in the "Eleventh Five-Year" research plan to conduct more extensive and in-depth research on Chinese toon, effectively develop and utilize high-quality Chinese toon resources, and promote my country's fast-growing better and faster The development of timber forest industry.
