Embodiment Construction

[0025] The technical characteristics of the present invention will be further elaborated below in conjunction with specific embodiments.

[0026] 1. Expansion:

[0027] Collect and clean the mature capsule seeds of wild Dendrobium officinale origin, soak them in 1% sodium hypochlorite for 10 minutes, wash them with clean water, soak them in warm water for 15 minutes, wrap them in gauze and put them in a clean petri dish to keep them moist , after it cracks, put it into the medium of MS basic medium+NAA (a-naphthoic acid) 0.4mg / L+potato juice 20% (V / V)+agar 7g / L, carry out seed germination culture, culture The temperature is 22-25°C, the light is 10 hours a day, and the light intensity is 1800-2500 lx. After about 2 weeks, the seeds gradually turn green, and a protocorm is formed in one month. Look with a magnifying glass, and you can see that the protocorm has needles; The protocorm is transferred to MS basic medium + BA (6-benzyl adenine) 0.2mg / L + potato juice 20% (V / V) + a...

Abstract

The invention discloses an industrial cultivation method for dendrobium candidum, belonging to the technical field of Chinese herbal medicine cultivation. The industrial cultivation method disclosed by the invention comprises the following steps of: taking freshly wild dendrobium candidum seeds as a raw material, thereby obtaining a dendrobium candidum sterile cultivating system; the industrial cultivation method comprises related technologies, such as seed treatment, seedling propagation, seedling tissue-cultivation and seedling training, transplantation and the like, so that the source of the dendrobium candidum seedlings and the geo-authentic character of the seedlings are effectively ensured; compared with the conventional seedling propagation, the seedling propagation speed is increased by 37%, the seedling training and transplantation survival rates are increased to above 90%, and the yield is increased by above 30%; and compared with the active ingredient content of wild dendrobium candidum, the dendrobium candidum, cultivated according to the method disclosed by the invention, comprises a same polysaccharide content as the wild dendrobium candidum, and slightly higher amino acid content as well as trace-element content than the wild dendrobium candidum.

Description

technical field [0001] The invention relates to a cultivation method of the medicinal plant dendrobium officinale, in particular to a factory cultivation method of the dendrobium officinale. Background technique [0002] Dendrobium candidum is an excellent variety of Dendrobium, also known as black knot grass, which is a perennial epiphytic herb of Orchidaceae. Dendrobium candidum has unique medicinal value. Its stems are used as medicine. The name of Chinese medicine is Dendrobium. .
