Mushroom is a kind of edible fungus planted indoors, which grows gradually from mycelium to fruiting body and eventually becomes an edible fungus, and can grow better and faster in a suitable environment. Mushrooms belong to saprophytic fungi, and there is no chlorophyll in their bodies, so they cannot directly carry out photosynthesis under light.

In the process of mushroom growth, various nutrients in the culture medium are mainly used as nutrient sources, thus achieving growth and development. Culture materials are generally composed of pig manure, cow dung, phosphate fertilizer and other substances.
