Alderleafed whitebeam scion grafting method

Abstract

The invention discloses an alderleafed whitebeam scion grafting method. The alderleafed whitebeam scion grafting method comprises the following steps that the portion, away from the ground by 20-25 cm, of fraxinus chinensis stock is stumped before grafting; one side of the section of the stock is cut once slightly to expose the cambium, and then the portion which is located at the inner side of the cambium and slightly has xylem is vertically cut by 2-3 cm; the side, without buds, of a scion is cut downwards into the bottom in the direction parallel to the scion axis, part of xylem is cut off, the section is 2-3 cm long, and the opposite side of the cut section is cut into a 45-degree small oblique plane with the length of 0.5 cm; the big cut face of the scion is inserted into a stock notch inwards, the cambium of the stock and the cambium of the scion are aligned, the upper end of the scion cut face need to be exposed by about 0.2 cm, the stock and the scion are bound from bottom to top, and a worker should pay attention to the requirement that the grafting portion cannot be exposed. The alderleafed whitebeam scion grafting method is convenient to operate, high in propagation speed, low in cost and short in seedling raising period and saves labor and materials, the grafting survival rate reaches 95% or more, and nursery stock is high in growth speed and good in quality.

Description

technical field [0001] The invention relates to the field of plant planting, in particular to a method for branch grafting of water catalpa. Background technique [0002] Water catalpa, a large tree of the genus Fraxinus in Oleaceae, the only precious tree species in the genus Fraxinus. Hi was born in moist and fertile soil. The tree is tall, with a straight and round trunk, fast-growing, excellent material, fine texture, relatively resistant to corrosion and moisture, and strong toughness. It is widely used in indoor decoration, machinery manufacturing, shipbuilding, vehicles, furniture, and inlaid wood floors. Although water catalpa is a precious tree species with strong stress resistance and high ecological and economic value, there are very few research reports on water catalpa at home and abroad, only a little research on seedling cultivation. No one has conducted a general survey and collection of its germplasm resources, let alone research on excellent provenance an...

Problems solved by technology

Water catalpa has been cultivated in the Xiaolongshan forest area for more than 60 years. It was once used as the main tree species of broad-leaved trees for afforestation on a large scale, but so far the preserved area is small and the preservation rate is low.

In the production, the seeds and seeds are mixed and multiplied, especially the short and inferior plants are easy to collect seeds, and the chances of reproduction are artificially increased. In addition, the variation and degradation of the seeded offspring lead to uneven forest trees, inferior species tend to be more, the forest is not neat, the population is degraded, and its own production potential is not high. can be played
