Problems solved by technology

[0004] In order to solve the technical problems that the existing camellia cutting propagation operation is random, the rooting rate is unstable, the quality of the root system is poor, the degree of automation management is low, and it cannot meet the requirements of industrialization and large-scale breeding, the present invention provides a method that can improve the quality of the root system, Improve and stabilize the higher rooting rate of camellia cutting propagation, shorten the seedling cultivation cycle, and can be suitable for industrialization and large-scale breeding of fine varieties, and can be accurately operated by single-bud soilless cutting propagation method of camellia

Embodiment 1

[0023] The female parent variety is 'Mr. Parkes' camellia variety, and the implementation location: Kunming City, Yunnan Province, longitude E102°41', latitude N25°01', altitude 1920m.

[0024] (1) Seedbed preparation: The seedbed is a brick-concrete structure with a width of 100cm, a length of 10m and a height of 20cm. The seedbed is built in a colorless and transparent plastic greenhouse, and the bottom layer of the seedbed is paved with 3-5cm thick perlite, and the geothermal wire is laid on the perlite, and the geothermal wire is covered with a 10cm thick cutting substrate. The cutting substrate is made of peat and The perlite is mixed according to the volume ratio of peat:perlite is 2:1; the cutting substrate on the seedbed is leveled and then watered thoroughly, and the seedbed and the ground in the plastic greenhouse are disinfected with 0.1% sodium hypochlorite solution. A high-pressure dense-mist automatic spray device is installed in the plastic greenhouse. The high-...

Embodiment 2

[0036] Repeat embodiment 1, have the following difference: select the Camellia cultivar ' fish scale armor ' that does not have damage by disease and insect, healthy growth as female parent. The volume ratio of the cutting substrate peat in the seedbed: perlite is 3:2.

[0037] Observation found that the camellia variety 'Yulianjia' began to form callus 20 days after cutting, new roots began to grow after 55 days, and a root system with a diameter of 3-4 cm was formed at the base of cuttings after 90 days, and the rooting rate reached more than 90%. .

Embodiment 3

[0039] Repeat embodiment 1, have the following differences: select the Camellia cultivar ' Liexiang ' that does not have damage by disease and insect, healthy growth as female parent.

[0040] It was observed that the camellia variety 'Liexiang' began to form callus 20 days after cutting, new roots began to grow after 55 days, and a root system with a diameter of 3-4 cm was formed at the base of the cuttings after 90 days, and the rooting rate reached more than 95%. .

Abstract

The invention discloses a single-bud soilless cutting propagation method of camellia. The method comprises the steps that a seedbed cutting matrix in a plastic greenhouse is prepared from peat and perlite, the volume ratio of the peat to the perlite is 2:1 or 3:2, floor heating lines are laid in a seedbed, and an automatic high-pressure thick mist spraying device is installed in the greenhouse; current-year semi-lignified branches of a maternal plant serve as cuttings, and a stem node, a leaf and a resting bud are retained on each cutting; in the cutting propagation period, the air temperature in the plastic greenhouse does not exceed 30 DEG C, and the temperature of the cutting matrix keeps at 20 DEG C-25 DEG C; the light intensity is 30,000-50,000 lx, the relative air humidity in the greenhouse is 85% or above, and the relative air humidity after rooting is 70%-85%; alternating spraying is performed with a 0.1% thiophanate methyl solution and a 0.1% chlorothalonil solution every other 10 days. According to the method, precise operation is achieved, the repeatability is high, the rooting rate reaches 85% or above, the propagation period is short, and transplanting can be performed after cutting is performed for 90-100 days.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and in particular relates to a single-bud soilless cutting propagation method of camellia. Background technique [0002] Camellia, which belongs to the genus Camellia of the family Theaceae, is a famous traditional flower in my country and a world-renowned precious ornamental flower. Its bright and changeable flower colors, beautiful appearance, dense green leaves, and never withering through winter are deeply loved by people from all over the world. China has abundant camellia resources, and the development potential of the camellia industry is great. [0003] At present, the production of potted camellias has reached a relatively large scale. The propagation methods of potted camellias mainly include grafting and cutting propagation. Domestic potted camellias are generally propagated by grafting, especially some rare and precious varieties of camellias. However, due to the high techn...
