King oyster mushroom, also known as the king of oyster mushrooms, has very high environmental requirements for its growth and development.

The king oyster mushroom that everyone usually uses for stir-frying is an edible mushroom that grows in the Mediterranean region of Europe, the Middle East and North Africa, but also in parts of Asia. It is named for its almond aroma and the thick, abalone-like texture of its flesh. The king oyster mushroom has thick flesh and a crisp, tender texture; in particular, the tissue of its stem is dense, firm and milky white, and the entire mushroom can be eaten. The stem is even crisper, smoother and more refreshing than the cap. It is called the “king of oyster mushrooms” and the “scallop mushroom”, and has a pleasant almond aroma and an abalone-like texture. It is suitable for preservation and processing, and is deeply loved by people. Sowhat environmental requirements does the king oyster mushroom have for growth?

1. What environmental requirements does the king oyster mushroom have for growth?

1. Temperature environment: King oyster mushroom mycelium prefers culture conditions of around 25°C; the suitable temperature for fruiting body growth is 10°C to 25°C, and the most suitable temperature is around 15°C.

2. Light environment: During the mycelium growth stage, the king oyster mushroom does not need any light conditions, and we should cultivate it away from light. However, the growth and development of the fruiting body requires an appropriate amount of scattered light.

3. Air environment: Both the mycelium and fruiting body growth of the king oyster mushroom require fresh air conditions. However, during the mycelium growth stage, a certain concentration of accumulated carbon dioxide actually stimulates and promotes the mycelium.

4. pH environment: The pH range that king oyster mushroom mycelium growth can adapt to is 4.5 to 8, the suitable substrate pH is 6 to 7, and the most suitable range is 5.5 to 6.5. Too low or too high a pH will cause varying degrees of inhibition on mycelium development.

5. Moisture environment: During artificial cultivation, it is advisable to adjust the moisture content of the substrate to about 65%; during the mycelium-running period, the air humidity of the culture room should be regulated to about 70%; during the fruiting stage, it should be maintained at 85% to 95% humidity to ensure the normal and healthy development of the fruiting bodies.

2. Where are the production areas of king oyster mushroom?

The natural distribution of king oyster mushroom production areas includes Italy, Spain, France, Germany, Czechoslovakia, Hungary, the southern part of the former Soviet Union, Morocco, India, Pakistan, and China's Xinjiang and western Sichuan, in alpine, grassland and desert zones.

King oyster mushroom is produced in many places in China, among which Shijiazhuang in Hebei and Tang County in Baoding have relatively large production scales.

3. When is king oyster mushroom generally planted?

For cultivation under natural conditions, according to the suitable growth temperature of king oyster mushroom, it is generally best to cultivate in autumn-winter and winter-spring, but in areas with higher temperatures in winter, it is better to schedule fruiting from December to February, because if the temperature is too high or too low, it is difficult to form primordia, which is not conducive to the growth and development of the fruiting bodies. King oyster mushroom is different from other oyster mushrooms: if the first flush does not form normally, it will affect the occurrence of the second flush, and will inevitably affect the total yield. Therefore, whether in the south or the north, the appropriate cultivation period should be arranged according to the suitable temperature for fruiting. Generally, it is advisable to prepare cultivation bags 50 days in advance when the local temperature drops below 18°C.
