Description

Additive for improving selenium content of dendrobe and preparation method thereof

Technical Field

The invention relates to the technical field of fertilizers, in particular to an additive for improving selenium content of dendrobium and a preparation method thereof.

Background

Selenium is a trace element necessary for human and animals, and has biological properties of scavenging free radicals, resisting oxidation, delaying aging, resisting cancer, enhancing immunity, antagonizing heavy metals and the like. Selenium is the active center of various enzymes in human body, and plays the roles of resisting diseases, delaying senility and enhancing immunologic function in life. Selenium has effects in protecting liver, resisting cancer, protecting cardiovascular system, regulating hormone secretion, antagonizing heavy metals, assisting radiotherapy and chemotherapy, treating cataract, and scavenging excessive free radicals. Selenium products play an important role in health food and pharmaceuticals.

Selenium is generally divided into two main categories of inorganic selenium and organic selenium: the former includes selenate, selenite, etc., inorganic selenium has poor absorption effect for human and animals, has large toxicity risk, and is easy to cause selenium poisoning when being used improperly; the latter mainly refers to selenium in a form combined with biological organic molecules, and the organic selenium has high absorptivity and low toxicity risk for people and animals, and is more suitable for the requirement of selenium supplement. Plants are the main source of selenium for humans and animals. In the nutritional effect of selenium compounds, organic selenium is greater than inorganic selenium, and plant selenium is greater than animal selenium. At present, the plant organic selenium cannot be artificially synthesized in China, the way of obtaining the plant organic selenium is mostly realized by a plant transformation technology, and the technology of improving the content of the organic selenium by utilizing the biotransformation of crops and entering a food chain for people and animals to eat is a main selenium-rich technology.

Dendrobe is a traditional famous and precious Chinese herbal medicine, which is listed as the head of the nine-large fairy grass in China from Tang and Song dynasties medical classics (Taoism Bidentis), and is always listed as a royalty tribute since Tang and Song dynasties. The dendrobium has unique medicinal value, belongs to yin-tonifying medicines in tonifying medicines by using the stem thereof as a medicine, and has the efficacies of tonifying stomach, promoting the production of body fluid, nourishing yin and clearing heat. Contains abundant herba Dendrobii polysaccharide, and has effects of enhancing immunity and relieving fatigue; the dendrobium has good inhibition effect on the helicobacter pylori which is a common pathogenic bacterium in the spleen and stomach diseases, can promote the secretion of gastric juice and the gastric emptying to help digestion; the dendrobium has better liver protection and cholagogic action, and is an essential drug for treating various liver and gallbladder diseases; the herba Dendrobii has effects of strengthening tendons and bones, lubricating joints, and resisting rheumatism; the dendrobium can enhance the activity of insulin and obviously reduce the blood sugar level; the dendrobium has strong anti-tumor activity, can reduce the side effects of radiotherapy and chemotherapy, improve the life quality and prolong the life time. In addition, the dendrobium has the effects of nourishing yin, nourishing eyes, nourishing skin and resisting aging.

The dendrobium nobile has extremely high health care and medicinal values, and the selenium is very important to the health of human bodies, so the selenium-rich dendrobium nobile developed by combining the dendrobium nobile and the selenium-rich dendrobium nobile is greatly welcomed by the market. However, the conventional selenium-rich dendrobium adopts a conventional fertilizer, so that the selenium content of the selenium-rich dendrobium cannot be increased, and the health-care effect of the selenium-rich dendrobium is influenced. Therefore, an additive for improving the selenium content of dendrobium and a preparation method thereof are expected to solve the problems in the prior art.
