Method for cultivating selenium-enriched officinal dendrobium stem

Abstract

The invention discloses a method for culturing the selenium-rich iron Dendrobium nobile, comprising: by applying the tissue culture, getting the iron Dendrobium nobile seed for sprout inducing in the sterility tube, primal bulb inducing and domesticating, then replanting it to the culture medium for the culture sprout growing, the composition of the culture medium during the sprout growing comprises per 1000 unit culture medium: macronutrient, 10 units; microelement, 1 unit; ferric salt, 5 units; banana, 100 units; fruitone, 2 units; sugar, 25 units; agar, 9 units; modifying the pH to be 5.6; sodium selenious acid with the concentration to be 200-300 ppm; and it comprises the following macronutrients: potassium nitrate, 14.1497g; amino sulfate, 2.3160 g; potassium phosphite, 2.0046 g; addex-magnesium, 0.9245 g; common salt, 0.6655 g; and the following microelements: potassium iodide, 0.8326 g; sodium permanganate, 0.2532 g; blue copperas, 0.0248 g; cobalt chloride, 0.0256 g; manganese sulfate, 22.3212 g; white copperas, 8.6281 g; boracic acid, 6.2308 g. The selenium-rich iron Dendrobium nobile got in this invention employs the iron Dendrobium nobile as the selenium carrier and transfers into the said product by the adsorption through Dendrobium nobile, and the absorption and utilization rate by human is high and is the most safe health food, combining the medical, nutriment, health and food together.

Description

technical field [0001] The invention relates to an artificial cultivation method of Dendrobium officinale, in particular to a cultivation method of selenium-enriched Dendrobium candidum. Background technique [0002] At present, 72% of the population in the country needs scientific supplementation of selenium, thus forming a potential large market for selenium-enriched products. At present, consumer groups in big cities in China, especially in some cities in the south of the country, are forming an upsurge of selenium supplementation, especially for selenium-enriched products. [0003] Selenium cannot be synthesized in the human body and must be ingested from the outside. However, the selenium content in the dietary structure of Chinese people is low. The Chinese Nutrition Society recommends a daily selenium intake of 60-200ug for normal human beings. Nutritional surveys in 13 provinces and cities in my country show that the daily selenium intake for adults is only 26.36ug,...

Problems solved by technology

[0008] In recent years, although my country has successively developed products such as selenium-enriched black fungus, selenium-enriched tea, selenium-enriched corn, selenium-enriched pear, selenium-enriched apple, selenium-enriched bean sprouts, and selenium-enriched yeast, different plants are subject to their own living conditions and environments. Different species have different culture methods. Dendrobium officinale itself is difficult to cultivate artificially, and inappropriate selenium abuse will affect the growth of Dendrobium officinale. There is no technical report on how to make Dendrobium officinale rich in organic selenium.
