Embodiment 1

[0049] Embodiment 1—Control experiment on rooting of Acer palmatum yellow Bazhang seedlings

[0050] Taking the cutting propagation of Acer palmatum Huangbazhang seedlings as an example, the above-mentioned embodiments were tested respectively. After the cuttings took root, the Acer palmatum Huang Bazhang seedlings obtained by propagation were managed in the same way under the same conditions, and were managed in a conventional water and fertilizer mode. Start seedling hardening until about 50 days after cutting. About 20 days after the hardening, the potting was transplanted, and the rooting cycle data list 1 of the Huangbazhang seedlings was measured as follows:

Embodiment 2

[0053] Embodiment 2—Control experiment on the survival rate of Acer palmatum yellow Bazhang seedlings

[0054] Taking the cutting propagation of Acer palmatum Huangbazhang seedlings as an example, the above-mentioned embodiments were tested respectively. After the cuttings took root, the Acer palmatum Huang Bazhang seedlings obtained by propagation were managed in the same way under the same conditions, and were managed in a conventional water and fertilizer mode. . Measure the survival rate of the Acer palmatum yellow Bazhang seedlings 70 days after cutting, and the obtained data list 2 is as follows:

Abstract

The invention discloses a method for acer palmatum ki-hachi-jo twig cutting propagation. The method comprises the working procedures of cottage bed preparation, cutting shoot collecting and treating, cutting and management after cutting. Ki-hachi-jo twigs are utilized for cutting in a greenhouse, and high-quality ki-hachi-jo seedlings are obtained by trimming cutting shoots in the early stage, carrying out hormone treatment, and controlling relative humidity, relative temperature, illumination, matrix water content of the growth environment in the later stage. According to the method for cutting propagation, the culture rooting rate and the survival rate of transplanting are high, the characteristic of good stains can be well kept, and the method can be directly applied to actual production and has good economic benefits, social benefits 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 and propagating twigs of Acer palmatum. 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. Acerpalmatum 'Osakazuki' is one of the horticultural variants of the Acer 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". Acerpalmatum 'Koto-no-ito' is one of many variant cultivars of Acer palmat...
