I: Varieties of Mushrooms

The varieties of mushrooms are: flat mushroom, golden needle mushroom, crab mushroom, apricot abalone mushroom, white jade mushroom, shiitake mushroom, tea tree mushroom, bifidobacterium mushroom, shiitake mushroom, shiitake mushroom, portobello mushroom, monkey head mushroom, white lingzhi mushroom, shiitake mushroom, floral mushroom, straw mushroom, shiitake mushroom, and so on. Edible mushrooms are widely distributed all over the earth, with more in deciduous forest areas. There are many types and numbers of wood fungi growing in mountain forests, such as shiitake mushrooms, fungus, silver fungus, monkey head mushrooms, matsutake mushrooms, crimini mushrooms and porcini mushrooms.

China is the first country in the world to domesticate and artificially cultivate shiitake mushrooms, fungus, golden ear, silver ear, straw mushroom, golden needle mushroom, monkey head mushroom, bamboo ear, etc. Now, Mongolian mushrooms and wild edible mushrooms have been domesticated, and boletus, porcini, morel mushroom, amanita, apricot, rivulet, boletus, and crimini mushrooms are also available for large quantity collection and are sold to the markets both at home and abroad.

Two: the growing environment of mushrooms

Temperature: mushrooms like to grow in an environment of about 18-20 degrees. The temperature should be adjusted to between 12-16 degrees when the substrate is growing at a later stage. If the temperature is too high, the substrate will become old. Nutrition: Mushrooms need a lot of nutrients to grow. A nutrient substrate needs to be prepared for planting, consisting mainly of animal manure and sawdust. Moisture: A lot of water is needed, and the humidity requirement is around 70%. Light: the growth of edible mushroom does not need light, strong light will affect the growth.

The temperature range for mushroom mycelium growth is 4-32°C, with 20-25°C being the most suitable. At 20-25°C, mycelium grows faster, denser and more robust. Mycelium grows fast above 25°C, but sparsely and weakly. If it reaches above 30°C, the mycelium will be destroyed and the viability will be reduced; below 15°C, the mycelium grows slowly. Winter can withstand 0 ℃ low temperature.

The suitable temperature for spore formation of mushroom substrate is 18-22°C. When the temperature exceeds 25°C, the spores will not be dispersed even if other conditions are suitable. Generally the spores can be dropped in about 2 days of culture, and the spores can be separated when the culture blood is dark brown. The suitable temperature for spore germination is 23-25°C. Too high or too low temperature will lead to prolonged germination time or even no germination.
