Problems solved by technology

[0007] In recent years, although various selenium-enriched crops have been developed successively in my country, different plants are subject to different living conditions and environments, and their cultivation methods are also different. Dendrobium huoshanense itself is difficult to cultivate artificially, and inappropriate selenium The abuse of elements will affect the growth of Dendrobium, how to make Huoshan Dendrobium rich in organic selenium has not yet been reported on the cultivation technology

Embodiment l

[0023] Embodiment 1: the preparation of organic selenium biological preparation

[0024] Self-made organic selenium conversion medium: 5 g sodium selenite, 30 g white sugar, 3 g calcium dihydrogen phosphate, 6 g dipotassium hydrogen phosphate, 0.5 g magnesium sulfate, 0.05 g calcium chloride, 1.25 g sodium citrate , 2.25 g of ammonium sulfate, 1.85 g of urea, 15 g / L of yeast powder, and 7.5 g / L of peptone were dissolved in water and adjusted to 1 L, and the pH value was adjusted to 7.0. After the medium was sterilized at 121 degrees Celsius for 30 minutes, the Add 5-7% EM active probiotics, mix well and carry out anaerobic fermentation in a sealed container at a fermentation temperature of 20-25°C for 7 days. After opening the cover, it has a sour and fragrant smell, and it is made into an organic selenium biological preparation.

Embodiment 2

[0025] Embodiment 2: the production of selenium-rich Dendrobium Huoshanense.

[0026] The organic selenium biological agent prepared in Example 1 was diluted with water to 100 times of the original volume. At this time, the selenium content is about 27mg / L. When the temperature is lower than 20 degrees Celsius at 3 o'clock in the afternoon from April to May and September to October, use a sprayer to spray the diluted organic selenium biological agent on the leaves and culture substrate of Dendrobium huoshanense, and do not spray on rainy days. The spray volume is 50mL / m 2 , Spray once every 5 days, and spray 6 times in total.

[0027] After being picked, it is made into finished products through the conventional production process of Dendrobium Huoshanense. The Dendrobium Huoshanense prepared by the process of the present invention is compared with the common Dendrobium Huoshanense of the same species (that is, not sprayed with an organic selenium biological agent) as a con...

Abstract

The invention discloses a method for producing selenium-rich dendrobium huoshanense by utilizing organic selenium biological agent, comprising the following steps: the biological agent which is rich in organic selenium and prepared by EM (effective microorganisms) probioltics is diluted to the selenium content of 20-30 mg/L, the biological agent is sprayed to the surface of the dendrobium huoshanense plant and culture medium respectively in April and September each year, the spray mount is 40-60 ml/m<2>, the biological agent is sprayed once every 5-7 days, and the biological agent is totally sprayed for 5-6 times. The leaves of dendrobium huoshanense to which the organic selenium biological agent is sprayed is rich in selenium, the dendrobium huoshanense accords with the limit standard of selenium-rich tea in NT/T600-2002 promulgated by the Ministry of Agriculture of China, so that the effects of disease prevention and disease resistance of the dendrobium huoshanense are better played, and the immune function of a human body is improved.

Description

technical field [0001] The invention relates to nutrition engineering transformation technology, in particular to a method for producing selenium-enriched dendrobium by utilizing the prepared organic selenium biological preparation. Background technique [0002] At present, scientific institutions and health organizations all over the world have unanimously recognized that selenium is one of the essential trace elements for human beings. At present, there are more than 40 kinds of human diseases related to selenium deficiency, including cancer, cerebrovascular disease, diabetes, liver disease, thyroid hormone imbalance and so on. It has been clinically proven that selenium can be used for anti-aging, prevention and treatment of coronary heart disease, diabetes, esophageal cancer, liver cancer, lung cancer, gastric cancer and other diseases. [0003] Selenium cannot be synthesized in the human body, and must be ingested from the outside. If the human body wants to maintain t...
