Problems solved by technology

It is well known that after sexual reproduction of Dendrobium officinale, its genetic characteristics are likely to change relative to the parent body, and the cultivators cannot know the quality of the cultivated seeds or new shoots after they grow into mature plants before cultivation
When cultivating, the cultivators need to take the risk that some cultivated plants will not be used in the future

Embodiment 1

[0017] Embodiment 1——Segmented cutting method

[0018] Cutting time: feasible throughout the year, the best time is from February to May.

[0019] Cutting container: a flat plate with a length*width*height of 54cm*27cm*6cm.

[0020] Cutting substrate: Soak sphagnum moss in clean water for 15 minutes, dehydrate, tear it apart, and lay it on a flat plate. The thickness of the laying is in the range of 2.5cm to 4.5cm, and the cutting substrate is watered with carbendazim solution with a mass content of 1‰ Disinfect and ensure that the humidity of the cutting substrate is in the range of 60%-80%.

[0021] Cultivation environment: plastic greenhouse, with sunshade nets outside the shed, and inner sunshade nets inside the shed. Double-layer sunshade nets are used to reduce light. The light intensity is controlled in the range of 1500-30000lus. When cutting, it is necessary to control the light intensity in a lower range and follow the iron The growth of Dendrobium gradually streng...

Embodiment 2

[0027] Embodiment 2——whole stem cutting method

[0028] Compared with Example 1, the whole-stem cutting method does not segment the cutting material, but adopts the method of whole-stem cutting: the pseudobulb cut from the parent body is removed from the first node at the top with the growth point, and the internodes are removed. The leaves are cut off, soaked in potassium permanganate solution with a mass content of 1‰ for 5 minutes, dried in a ventilated place, and placed flat in the cutting matrix.

Abstract

The invention relates to a cuttage cultivation method of Dendrobium officinale. The method comprises the following steps: (1) cuttage material preparation: extracting the pseudobulb from the root of the parent plant and serving as the cuttage material; (2) cuttage material segmentation: cutting the pseudobulb into cutting shoots and allowing 2 to 3 nodes of each cutting shoot, cutting off leaves between the nodes, and soaking the cutting shoots in the potassium permanganate solution and then air-drying; (3) shoot cuttage: inserting the cutting shoots in a prepared cuttage matrix, watering and covering with a wet non-woven fabric; (4) cutting shoot management: keeping the cultivation environment semi-shady and moist, maintaining the temperature in the range from 5 DEG C to 35 DEG C and ensuring the illumination in the range from 1500 to 5000 lux; and (5) transplanting: cutting off the regenerated plant by using a pair of sterilized scissors and transplanting to a transplantation matrix. By adopting the cuttage cultivation method, the cultured plant retains the excellent quality of the parent plant and is free from mutation. The cuttage cultivation method has the advantages of foreseeable cultivation result, low cultivation risk and short cultivation period.

Description

technical field [0001] The invention relates to an artificial cultivation method of dendrobium candidum, in particular to a cutting cultivation method of dendrobium candidum. Background technique [0002] Dendrobium officinale, also known as Dendrobim officinale Kimra et Migo, belongs to the phylum Angiosperms, Monocotyledons, Microorders, Orchidaceae, and the genus Dendrobium. It is a precious medicinal material. Due to the destructive excavation by the farmers in the production area, the wild resources of Dendrobium candidum are on the verge of extinction. The state encourages scientific research institutions, enterprises and institutions to artificially cultivate Dendrobium candidum. The Chinese invention patent "Artificial Large-scale Cultivation Method of Dendrobium officinale" with the application number CN 200410084496.1 discloses a method of using the seeds of Dendrobium officinale to obtain good social and economic benefits through unique multiplication, training, t...
