Problems solved by technology

However, selenium-enriched Dendrobium officinale has strict requirements on the growth environment, and it is difficult to grow seedlings. Traditional artificial propagation methods such as branching and cuttings are used for propagation, and the proliferation rate is very low. Restricted the expansion of the production scale of selenium-enriched Dendrobium officinale

Abstract

The invention discloses a culture method for selenium-rich dendrobium officinale kimura ex migo with a high transplanting survival rate. The culture method comprises the following steps: obtaining a sterile dendrobium officinale kimura ex migo stem fragment; cutting the sterile dendrobium officinale kimura ex migo stem fragment into a thin slice along the cross section, so as to obtain a tissue thin slice; putting the tissue thin slice into an induction culture medium and carrying out germination of a protocorm, so as to obtain the protocorm; inoculating the protocorm into a proliferation culture medium and carrying out proliferation of the protocorm, so as to obtain a proliferated protocorm; inoculating the proliferated protocorm into a rooting culture medium and carrying out rooting culture to obtain a tissue culture seedling; inoculating the tissue culture seedling into a seedling culture medium and culturing to obtain a seedling; transferring the seedling into a grown-up seedling culture medium and culturing to obtain a grown-up seedling. According to the culture method disclosed by the invention, the cultured selenium-rich dendrobium officinale kimura ex migo seedling has theadvantages of good growth, high transplanting survival rate and stable quality, so that the expansion of a production scale of the selenium-rich dendrobium officinale kimura ex migo is facilitated.

Description

technical field [0001] The invention relates to the technical field of dendrobium cultivation, in particular to a method for cultivating selenium-enriched dendrobium officinale seedlings with high transplanting survival rate. Background technique [0002] Selenium is an essential trace element for humans and animals. It has biological properties such as scavenging free radicals, anti-oxidation, anti-aging, anti-cancer, enhancing immunity, and antagonizing heavy metals. Selenium is generally divided into two categories: inorganic selenium and organic selenium: the former includes selenate, selenite, etc. Inorganic selenium is poorly absorbed by humans and animals, and has a high risk of toxicity. Improper use can easily cause selenium poisoning; the latter The former mainly refers to the form of selenium combined with biological organic molecules. For humans and animals, organic selenium has a high absorption rate and low toxicity risk, which is more suitable for the requirem...
