Most kinds of russula are edible, nutritious and delicious, and have the reputation of "king of mushrooms", which is a natural nutritional product with high nutritional value. Russula is rich in essential amino acids, vitamins, fatty acids and steroids, pigments and antibiotics.
The artificial cultivation of Russula is extremely difficult, which is embodied in the following aspects: the spores of Russula are difficult to germinate under artificial conditions, and the dependent ecological environment is too complicated, which leads to the regulation of fruiting by many factors. At present, tissue isolation is the only way to obtain Russula strains, and pure Russula strains can only be obtained after multiple separations.
