Problems solved by technology

[0003] With the deepening of industrialization and economic development, it has also brought environmental pollution, especially the intensification of heavy metal pollution, and the raw materials for edible fungus cultivation have also received varying degrees of pollution. If we still cultivate according to traditional methods, the The cultivated edible fungi may also contain more or less pollutants, resulting in a decrease in the nutritional value of the edible fungus and reducing the health benefits of the edible fungus
[0004] At present, some progress has been made in the research on fungal polysaccharides, mainly focusing on how to extract fungal polysaccharides and how to improve the extraction method of polysaccharide content, but little is known about how to improve the cultivation of tremella polysaccharides

Abstract

The invention discloses a cultivation method for increasing the polysaccharide content of tremella. The cultivation method comprises various measures of: selecting a stock culture medium, a cultispecies culture medium, a substrate and the color of a film, managing fertilizers and water, controlling temperature difference between day and night and carbon dioxide in a greenhouse and the like, and finally, the polysaccharide content of the tremella treated by the cultivation method is increased by 16%.

Description

technical field [0001] The invention relates to a cultivation method, in particular to a cultivation method for increasing the polysaccharide content of white fungus. Background technique [0002] In recent years, many polysaccharides have been found in fungal research not only have anti-tumor and high immune effects, but also have good pharmacological and clinical value, and have been developed into clinical drugs. Modern scientific research has proved that edible fungus polysaccharides can enhance the body's immunity and cellular immunity; it can excite the reticuloendothelial system and protect the animal liver; it has broad-spectrum anti-virus, anti-tumor immunity and Solubilization of cholesterol. At present, no suitable agent has been found for the treatment of plant virus diseases in the world. Therefore, looking for immune enhancers is one of the directions for developing new drugs today, and fungal polysaccharides are ideal new immune agents. It is non-toxic and s...
