Problems solved by technology

[0003] Vietnamese cinnamon seedlings are scarce in my country. my country began to introduce them in 1960, and there are a small amount of cultivation in Guangdong, Guangxi, Hainan and other regions. The traditional domestic cinnamon planting conditions are not applicable to the cultivation of Vietnamese cinnamon, and there are currently no methods for raising Vietnamese cinnamon seedlings. Many deficiencies lead to the low quality of domestic Vietnamese cinnamon products, so breeding excellent strains is particularly important for the large-scale promotion and planting of Vietnamese cinnamon
At present, Vietnamese cinnamon is generally used for seedling cultivation, and seeds on 15-year-old robust cinnamon plants are generally selected, which greatly limits the large-scale promotion and planting of Vietnamese cinnamon.
Cutting propagation technology has the characteristics of maintaining the excellent traits of the parents, but Vietnamese cinnamon is difficult to root tree species, and there are very few studies on the asexual propagation of Vietnamese cinnamon

Embodiment 1

[0037] Embodiment 1 A kind of Vietnamese cinnamon cutting propagation method

[0038] 1. Cutting method

[0039] S1. Seedling bed preparation: use peat soil, loam, sand and vermiculite to form a mixed substrate in a volume ratio of 2:2:1:1, establish a seedbed, and use 0.1% carbendazim aqueous solution for the mixed substrate 3 days before cutting. disinfect;

[0040] S2. Preparation of cuttings: Select 150 3-year-old branches of 8-year-old Vietnamese cinnamon plants free from diseases and insect pests, cut the lower incision obliquely and the upper incision flatly, and cut the branches to a length of 8-15 cm, ensuring that each cutting has 3-6 pieces leaf bud;

[0041] S3. Preparation of 100mg / L indole butyric acid solution: take 50ml of alcohol with a mass fraction of 95%, dissolve 100mg of indole butyric acid in alcohol, add water to the solution to dilute to 1000ml after dissolving to obtain 100mg / L Indole butyric acid solution;

[0042] S4. Cuttings pretreatment: Soak...

Embodiment 2

[0050] The screening of the branch of embodiment 2 different old and tender degrees

[0051] The experimental procedure is the same as in Example 1, except that the branches selected during the preparation of cuttings in step S2 are different, as shown in Table 2.

[0052] Table 2

[0053]

[0054] From the data in Table 2, it can be found that using the 6-12 year-old Vietnamese cinnamon shoots to make cuttings, the seedling rate and rooting rate are far lower than the 2-3 year-old branches, and the present invention also finds that when the 4-5-year-old branches are selected, When the branches are grown, the seedling rate and rooting rate are not as good as the 2-3 year old branches.

Embodiment 3

[0055] The screening of different seedbed substrates of embodiment 3

[0056] 1. Experimental method

[0057] The experimental procedure is the same as that in Example 1, except that the substrate of the seedbed in step S1 is different, as shown in Table 3 for details.

[0058] table 3

[0059]

[0060]

[0061] From the data in table 3, it can be found that according to the above first 6 kinds of matrix treatments, its seedling rate and rooting rate are all lower than peat soil, loam, sandy soil and vermiculite as the matrix treatment of 2:2:1:1, especially When the ratio of river sand: vermiculite is 2:1, the rooting rate of Vietnamese cinnamon is the lowest.

Abstract

The invention provides a cutting propagation method of Cinnamomum loureirii Nees. According to the cutting propagation method, a seedling-raising bed is established by virtue of proper twigs of the Cinnamomum loureirii Nees, and effective preprocessing and timely cutting and reasonable culture management are carried out on cutting slips, so that rooting of the cutting slips of the Cinnamomum loureirii Nees is promoted, the rooting rate and the seedling emergency rate are increased, the final cutting survival rate of the Cinnamomum loureirii Nees reaches up to 85% or above, the propagation coefficient of the Cinnamomum loureirii Nees is increased, and the problems of recession, mutation and the like are avoided. The cutting propagation method is beneficial to maintenance of excellent characters of Cinnamomum loureirii Nees seedlings; and an important technique support is provided for large-scale production and stable character inheritance of the Cinnamomum loureirii Nees seedlings and establishment of a fine-variety female parent orchard; and a technical reference is provided for clonal propagation of other lauraceae plants.

Description

technical field [0001] The invention relates to the field of cinnamon planting, in particular to a Vietnamese cinnamon cutting propagation method and application thereof. Background technique [0002] Vietnamese cinnamon (Cinnamomum loureirii Nees.) belongs to the family Lauraceae. It is a tropical and subtropical evergreen tree. It is native to Changchun County, Thanh Hoa Province, Vietnam, and is also distributed in Guangnan, Quang Ninh and other provinces. Vietnamese cinnamon likes warmth and humidity, but young trees like shade and need proper shade to grow, while mature trees like light and need more sunlight. The cinnamon bark oil content of Vietnamese cinnamon is as high as 3.08%, and the content of trans-cinnamaldehyde is as high as 81.97%. The economic benefit is higher than that of Chinese cinnamon. Vietnamese cinnamon is a commonly used traditional Chinese medicine. It has the effects of nourishing fire and yang, dissipating heat and relieving pain, promoting blo...
