mushroom

Mushrooms belong to Agaricus, Agaricus, Agaricus, also known as fungi. Many countries have cultivated it, and the total output of China ranks second in the world.

In recent years, with the rapid development of edible fungi industry, the output of Agaricus bisporus is also increasing year by year, which has become a pillar industry to increase farmers' income in many areas. With the improvement of people's living standards, the consumption demand for mushrooms is increasing every year, and the industrial cultivation of Agaricus bisporus has also begun to be realized.

Knowledge expansion:

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.

Mushroom growth is mainly divided into two stages: mycelium growth and fruiting body growth. At different growth stages, mushrooms have different requirements for temperature. The optimum temperature range is 18~20℃ in the mycelium growth stage and 12~ 16℃ in the fruiting body growth stage.

Temperature control is very important in all stages of mushroom growth. If the temperature is too high, the development of mycelium will be accelerated, but it will be very fine. This mycelium is prone to aging and premature aging, and it will be easy to open the umbrella when it grows to fruiting body. If the temperature is lower than 4℃, both mycelium and fruiting body will stop growing.

The water content of mushroom fruiting body is extremely high, about 90%. In the actual cultivation of mushrooms, the humidity of the culture material should be controlled at 55%~60%. If the environment is too dry, the growth of mushrooms will be seriously affected.

Too wet will affect air circulation, and hyphae and fruiting bodies will gradually die. Therefore, the control of moisture should be very accurate, which is a problem that needs attention in actual cultivation and an important principle to be followed in mushroom cultivation.
