A fungus is a creature. In order to survive and grow, they need to eat a lot of nutrients. The most basic are carbon source, nitrogen source and trace elements. Carbon source mainly comes from organic matter, such as sugar, straw, wood and so on. Nitrogen sources mainly come from amino acids, urea, nitrates and other compounds. In addition, fungi also need to ingest a small amount of elements such as potassium, calcium, magnesium, phosphorus and iron, which are very important for their growth and reproduction.

2. The ideal environment for fungus growth

Besides essential nutrition, the growth of fungi also needs suitable environmental conditions. The most important things are temperature and humidity. Different kinds of fungi have different requirements for temperature and humidity, but generally speaking, the ideal growth temperature of fungi is between 20~30℃ and the humidity is above 50%. In addition, fungi also need adequate oxygen supply, otherwise it will lead to suffocation and death.

3. Fungal growth substrate

The growth of fungi needs a certain growth substrate to support it. Different kinds of fungi have different substrates suitable for growth. For example, some wood rot fungi are suitable for growing in wood; Some edible fungi need to grow in a suitable bed. If the growth substrate is too dry or lack of nutrition, fungi can't grow or grow slowly.

4. What tools and techniques are needed to cultivate fungi artificially?

Artificial cultivation of fungi requires some special tools and techniques. Among them, the most basic equipment includes fermentation tank, culture medium, temperature and humidity controller, etc. At the same time, cultivating fungi requires corresponding knowledge and skills, such as the preparation of culture medium, disinfection of washing equipment and so on. In addition, when cultivating different kinds of fungi, it is necessary to master some targeted techniques, such as inoculation, fermentation, separation and so on.
