Embodiment 1

[0048] Example 1—Control experiment on rooting of Acer palmatum Jinling Huangfeng seedlings

[0049] Taking the cutting propagation of Acer palmatum Jinling Huangfeng seedlings as an example, the above-mentioned examples were tested respectively. After the cuttings took root, the Acer palmatum Jinling Huangfeng seedlings that were propagated were managed in the same way under the same conditions, and were treated with conventional water and fertilizer. The way of management is until about 50 days after the cutting, the seedlings are hardened. About 20 days after the seedlings were hardened, they were transplanted in pots, and the rooting period of Jinling Huangfeng seedlings was measured according to Table 1 as follows:

[0050] Table 1—Experiment on the rooting cycle of Acer palmatum Jinling Huangfeng seedlings

[0051] test subject

Embodiment 2

[0052] Example 2—Control experiment on the survival rate of Acer palmatum Jinling Huangfeng seedlings

[0053] Taking the cutting propagation of Acer palmatum Jinling Huangfeng seedlings as an example, the above-mentioned examples were tested respectively. After the cuttings took root, the Acer palmatum Jinling Huangfeng seedlings that were propagated were managed in the same way under the same conditions, and were treated with conventional water and fertilizer. way management. The survival rate of the Acer palmatum Jinling Huangfeng seedlings was measured 70 days after cutting, and the obtained data list 2 is as follows:

Abstract

The invention discloses a method for propagating twigs of acer palmatum Jinling Haungfeng by cutting. The method comprises the steps of cutting bed preparation, cutting shoot collection and treatment, cutting process and after-cutting management process. A high-quality Jinling Huangfeng nursery stock can be obtained by cutting a Jinling Huangfeng twig in a greenhouse, conducting clipping and hormone treatment on a cutting shoot in the early stage and controlling relative humidity, relative temperature, lighting, moisture content of matrix and the like in a late growing. The cutting propagation method has a high culture-rooting rate and a high transplanting survival rate, can well maintain the characteristics of excellent strains, can be directly applied to practical production, and has relatively good economic benefit, social benefit and ecological benefit.

Description

technical field [0001] The invention relates to the technical field of plant asexual propagation, in particular to a method for cutting propagation of Acer palmatum Jinling Huangfeng twigs. Background technique [0002] Acer palmatum (Acerpalmatum), also known as maple palmatum, belongs to the small deciduous trees or shrubs of the Aceraceae family. As an excellent ornamental colorful leaf plant, it has a long history of application in Chinese gardens, and it is more common in today's urban gardens. Jinling Huangfeng is a new variety with colorful leaves selected from the seedlings of Acer palmatum. The new shoots are bright red, the color of the annual branches is slightly reddish, and the biennial branches are green. Sprout in late March, new buds are bright orange-red; young leaves are yellow, leaf margins are light coral red; leaf color is golden yellow during vigorous growth period; mature leaves turn yellow-green from September to October, and new leaves on autumn sh...
