Problems solved by technology

[0002] In the traditional breeding method of Chinese golden leaf elm, the grafting method is the main method. The problem is that the grafting process has strict technical requirements for the scion and grafting workers. In addition, the grafting and breeding process is slow, and the seedling output is low, which cannot meet the market demand, which leads to the price of golden leaf elm seedlings. High, which has a certain impact on the landscaping in northern my country

Embodiment 1

[0011] Select the semi-lignified branches of Ulmus japonica with a length of 5-10cm, at least 3 buds, and a thickness of at least 0.2cm to cut. Use a sharp tool when cutting. After cutting, remove 1 / 3 of the leaves at the base. Leaves with strong photosynthesis are retained; first with dehydrated alcohol, indole butyric acid is completely dissolved, then poured into water to dilute as a rooting agent, and the concentration of indole butyric acid in the rooting agent is controlled to be 1000ppm, and the sheared Put the 2cm of the base of the cutting ear into the prepared rooting agent and dip it for 20 seconds, and then cut it in mid-June.

[0012] Cuttings can be cut along with the treatment, one plant per hole, cutting depth 3cm, spray water after cutting to keep the branches in close contact with the substrate, and continue for 7 days to maintain the humidity of the substrate, that is, continue to spray water to maintain the humidity of the substrate to avoid cutting spikes ...

Embodiment 2

[0015] Select the semi-lignified branches of Ulmus japonica with a length of 5-10cm, at least 3 buds, and a thickness of at least 0.2cm to cut. Use a sharp tool when cutting. After cutting, remove 1 / 3 of the leaves at the base. Leaves with strong photosynthesis are retained; first fully dissolve indole butyric acid with dehydrated alcohol, then pour into water to dilute as a rooting agent, control the concentration of indole butyric acid in the rooting agent to be 900ppm, and cut the indole butyric acid Put the 3.0cm of the base of the cutting ear into the prepared rooting agent and dip it for 30 seconds, and then cut in the first ten days of July.

[0016] Cuttings can be cut along with the treatment, one plant per hole, cutting depth 2cm, spray water after cutting to keep the branches in close contact with the substrate, and keep the substrate humidity for 6 days, that is, keep spraying water to keep the substrate humidity to avoid cutting spikes Dehydration wilting is the m...

Abstract

The invention relates to a cutting propagation method of Ulmus pumila cv. jinye. The cutting propagation method is characterized by comprising the steps of: cutting semi-lignified branches, with length of 5-10 cm, at least three buds and diameter of at least 0.2 cm, of current-year ground-grafted Ulmus pumila cv. jinye, and removing 1 / 3-1 / 4 leaves at the bottom part after cutting; dipping the bottom part with length of 1.5-3.0 cm of the cut cuttage scion into a rooting agent for 5-30 seconds, and then carrying out cuttage during from the middle ten days of May to the first ten days of July, wherein cuttage and treatment are sequentially carried out, one plant is inserted into one hole by hole tray cuttage and the cuttage depth is 2-3 cm; after cuttage, spraying water to maintain close contact between the branches and the medium, and maintaining for 6-7 days to maintain the medium humidity; and entering a domesticating stage when the rooting rate of the cuttage scion achieves 75-90%, domesticating for 10-15 days and carrying out field planting. According to the cutting propagation method provided by the invention, the cuttage survival rate of Ulmus pumila cv. jinye in a micro-spraying environment can achieve more than 90%, and the seedlings are tidy, strong in growth vigor aftereffect and excellent in commodity property.

Description

technical field [0001] The invention relates to a cutting propagation method of Ulmus chinensis. Background technique [0002] In the traditional breeding method of Chinese golden leaf elm, the grafting method is the main method. The problem is that the grafting process has strict technical requirements for the scion and grafting workers. In addition, the grafting and breeding process is slow, and the seedling output is low, which cannot meet the market demand, which leads to the price of golden leaf elm seedlings. High, which has a certain impact on the landscaping in northern my country. Contents of the invention [0003] The object of the present invention is to provide a cutting propagation method of Ulmus chinensis, which can increase the breeding speed of seedlings, reduce production costs, and have a high survival rate. [0004] In order to achieve the above object, the technical solution adopted in the present invention is. [0005] A cutting propagation method of...
