Embodiment 1

[0020] A kind of propagation method of camphor tree, comprises the following steps:

[0021] (1) cultivation body selection: reach about 20 ℃ in autumn temperature, select good seed quality, tree body health, no damage by disease and insect, and the half-lignified twig of the year on the camphor tree seedling of 1 year is made cultivation body;

[0022] (2) Detoxification of the culture body: Rinse the selected culture body with clean water, disinfect it with 75% alcohol alcohol for 30 seconds in the aseptic laboratory, and then sterilize it with 0.1% mercuric chloride for 5 minutes. Rinse with water 3 times, dry the filter paper and set aside;

[0023] (3) value-added culture: the culture body is cut into 1.5cm of the segment with axillary buds, and then cultured on the culture medium, the callus induction medium is MS, and when the bud tip grows 2cm, it is inoculated into the culture medium for value-added culture; This step is not required when the selected culture body is...

Abstract

The invention discloses a breeding method for cinnamomum camphora. The breeding method includes the following steps that annual semi-lignification twigs at the autumn temperature of about 20 DEG C andon 1-2-year-old cinnamomum camphora seedlings are selected as cultivating bodies; the selected cultivating bodies are washed to be clean with fresh water, sterilized for 30 s with alcohol of 75% in asterile laboratory, then sterilized for 5 minutes to 10 minutes with mercury bichloride of 0.1% and washed three times with sterile water; the cultivating bodies are cut into 1.5-cm-to-2-cm small sections with axillary buds, and the small sections are inoculated onto an MS culturing medium for culturing and inoculated into a culturing medium for culturing when 2-cm shoot tips grow; if the selected cultivating bodies comprise stem tips and leaf buds, the previous step is avoided, but the cultivating bodies are sterilized and directly inoculated into the culturing medium for enrichment culturing; after the cultivating bodies are subjected to enrichment culturing for 35 days to 45 days, the growth condition of enrichment culturing seedlings is observed, and when the seedlings grow to have the height of 8 cm to 10 cm and the length of roots is larger than 5 cm, transplanting can be conducted. The breeding method for the cinnamomum camphora has the advantages that the survival rate of thecinnamomum camphora can be increased, the cultivating periods of the cinnamomum camphora can also be shortened, and the cultivating quantity of the cinnamomum camphora can also be decreased.

Description

technical field [0001] The invention relates to the technical field of plant cultivation, in particular to a breeding method of camphor trees. Background technique [0002] Camphor trees are distributed in southern and southwestern provinces and autonomous regions of China. It is also distributed in Vietnam, North Korea, and Japan, and it is often introduced and cultivated in other countries. The entire plant has a camphor aroma, which can be used to extract camphor and camphor oil. The wood is hard and beautiful, suitable for making furniture and boxes. Camphor tree is resistant to harmful gases such as chlorine, sulfur dioxide, ozone and fluorine, can repel mosquitoes and flies, and can withstand short-term flooding. It is the main raw material for the production of camphor. The material is high quality and is a good material for making furniture. The camphor tree grows slowly, and the cultivation period is long. Most of them come from large trees transplanted in the m...
