Problems solved by technology

[0003] At present, in the propagation system of Dendrobium candidum test-tube seedlings, the rooting medium adopts solid medium. The application of solid medium not only increases the production cost, but also easily causes root damage when taking seedlings, and reduces the survival rate of transplanting.

experiment example 1

[0028]Under aseptic conditions, get the stem section of Dendrobium officinale with axillary buds of 2-2.5 cm in length with 3-5 stem sections as explants, and place the explants in formula one, two, three, four, five respectively. The culture medium and common MS culture medium (formulation 6) were cultivated, culture conditions: temperature 25°C, light condition 2000LX, light time 12h / d, and compared after 25 days of culture.

[0029] Table 1 Comparison table of polysaccharide content and growth status

[0030]

[0031] The experimental results show that the polysaccharide content of Dendrobium officinale can be significantly increased by using the culture solution of the present invention to cultivate the stem segments of Dendrobium officinale.

experiment example 2

[0033] Under aseptic conditions, get the stem section of Dendrobium officinale with axillary buds of 2-2.5 cm in length with 3-5 stem sections as explants, and place the explants in formula one, two, three, four, five respectively. Stem segment proliferation and expansion was carried out with the culture medium and common MS culture medium (recipe 6). The culture conditions were: temperature 25°C, light condition 2000LX, and light time 12h / d.

[0034] Table 2 Comparison table of stem segment proliferation and expansion

[0035]

[0036] The experimental results show that the cultivation period of Dendrobium officinale can be significantly shortened by using the culture solution of the present invention to cultivate the stem segments of Dendrobium officinale.

Abstract

The invention discloses a Dendrobium officinale culture solution and belongs to the technical field of agricultural planting. The culture solution comprises the following ingredients: potassium nitrate, ammonium nitrate, magnesium sulfate, manganese sulfate, zinc sulfate, monopotassium phosphate, copper sulfate, potassium iodide, cobalt dichloride, boric acid, sodium molybdate, vitamin VB1, vitamin VB6, vitamin VB5, glycine, ferrous sulfate, disodium ethylenediamine tetraacetic acid, calcium chloride, naphthylacetic acid, mashed banana, mashed potato, white sugar, inositol, and powdered agar. The dendrobium officinale culture solution is reasonable in compatibility, can provide comprehensive nutrition for a Dendrobium officinale stem, fast promote the stem to grow out of a root, increase the polysaccharide content and the amino acid content in the Dendrobium officinale, shorten the time for culturing the Dendrobium officinale stem to a complete plant to about 25 days, and significantly improve the transplanting survival rate of the Dendrobium officinale.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, and in particular relates to a culture solution of dendrobium candidum. Background technique [0002] Dendrobium officinale is a perennial epiphytic herb of Orchidaceae. Born on the semi-shady rocks in the mountains at an altitude of 1600 meters, it likes warm and humid climates and semi-shady and semi-yang environments, and is not cold-resistant. Generally, they can withstand low temperatures of -5°C. Dendrobium can be divided into dozens of species such as yellow grass, nobile, and horsewhip. Dendrobium candidum is the best product of Dendrobium. It is named for its iron-green skin. Dendrobium candidum has unique medicinal value, and its stem is used as medicine. The name of the traditional Chinese medicine: Dendrobium, belongs to the yin-tonifying medicine in the tonic medicine. "Chinese Pharmacopoeia": Yiwei Shengjin, nourishing yin and clearing heat. [0003] At present, in ...
