Embodiment 1

[0051] Embodiment 1—Control test on rooting of Acer palmatum seedlings

[0052] Taking the cutting propagation of Acer palmatum seedlings as an example, the above-mentioned examples were tested respectively. After the cuttings took root, the Acer palmatum seedlings that were propagated were managed in the same way under the same conditions, and were managed in a conventional way of water and fertilizer. Start seedling hardening until about 50 days after cutting. About 20 days after the seedlings were hardened, they were transplanted in pots, and the rooting cycle data list 1 of the Acer palmatum seedlings was measured as follows:

Embodiment 2

[0055] Embodiment 2—Contrast experiment on survival rate of Acer palmatum seedlings

[0056] Taking the cutting propagation of Acer palmatum seedlings as an example, the above-mentioned examples were tested respectively. After the cuttings took root, the Acer palmatum seedlings that were propagated were managed in the same way under the same conditions, and were managed in a conventional way of water and fertilizer. . Measure the survival rate of the gained Acer palmatum seedlings 70 days after cutting, and the gained data tabulation 2 is as follows:

Abstract

The invention discloses a method for acer palmatum gold thread twig cuttage. The method comprises the steps of cuttage bed preparation, cutting slip collecting and processing, cuttage, management after cuttage. Gold thread twigs are utilized for cuttage inside a greenhouse, and high-quality gold thread nursery stocks are obtained through early-stage cutting slip clipping and hormone treatment and control over relative humidity, relative temperature and illumination of the growing environment of the later stage and the water content of a substrate. According to the method for cuttage, the culture rooting percentage is high, the survival rate of transplanting is high, the features of the good strain can be well kept, and the method can be directly applied to actual production and has the good economic, social and ecological benefits.

Description

technical field [0001] The invention relates to the technical field of plant vegetative propagation, in particular to a method for cutting propagation of Acer palmatum 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. Golden thread (Acerpalmatum 'Osakazuki') is one of the horticultural variants of the maple palmatum. For deciduous trees, the growth rate slows down with the growth of the plant, and its leaves are leathery. Under the condition of suitable water and fertilizer, the leaves are not easy to be burned. Yellow-green with reddish leaves in spring, dark green in summer and intense crimson in fall, it has been likened to a "burning bush". Golden thread (Acerpalmatum 'Koto-no-ito') is one of many var...
