In the production of edible fungi, the cultivation of the mother species is a crucial part. At present, the producers adopt the PDA medium and the PDA medium is complex. High cost, used as the original adapter, hair invasion, easy to pollute. The author after years of exploration, according to the basic nutritional requirements of mycelium, after repeated research to find suitable for all kinds of mushroom growth of broad-spectrum medium, it is not only suitable for the expansion of the mother of the expansion,
