Red mushroom is a large class of mycorrhizal fungi belonging to the subphylum basidiomycetes, the order Laminae, the order Umbellifera, the family Red Mushroom, and the genus Red Mushroom. It is a valuable wild edible (medicinal) fungus. Widely distributed in the world, China is mainly distributed in Fujian, Yunnan, Jiangxi, Liaoning, Henan, Sichuan, Guangxi and other provinces and regions, the altitude is 300 ~ 1000m mountain forest area, vegetation and soil vertical distribution is obvious, slope 10 ° ~ 45 ° gentle slope to slope.
Most of the species of red mushrooms are edible, and rich in nutrition, delicious taste, have the reputation of "the king of mushrooms", are natural nutrition products, and have high nutritional value. Red mushrooms are rich in essential amino acids, polysaccharides, organic acids, vitamins, fatty acids and steroids, pigments and antibiotics.
Red mushrooms are mainly grown on red-brown soil or red soil slopes, and the soil is generally rich in humus, which is loose, ventilated and water-retaining, and is rich in organic matter. The soil pH of the place where it grows is weakly acidic.
Climatic conditions are important influencing conditions for the occurrence of red mushrooms, which directly affect the time of occurrence of fruiting bodies of red mushrooms every year, and also related to production. Red mushroom fruiting bodies generally need rainfall before occurrence, and after rain need to be sunny, the amount of rainfall and whether it is sunny after rain directly affect the production of red mushrooms. The exchange of rain and sunny weather can provide the following conditions for the occurrence of fruiting bodies of red mushrooms: suitable humidity, temperature, and the creation of suitable metabolic conditions for symbiotic plants, thereby providing the carbohydrates and other nutrients needed for the growth of fruiting bodies.
