What kind of growing environment is suitable for pearl mushrooms

Pearl mushrooms, also called nameko mushrooms, originated in Japan, and are now cultivated in many places around the world. They were introduced to China for cultivation in the 1970s. Because their surface has a layer of slippery mucus, they are called slippery mushrooms. They are a world-famous artificially cultivated edible mushroom. So what kind of environment does this edible mushroom mainly grow in, and where is it suitable to cultivate? What are the requirements for artificial cultivation? Please continue reading below to learn more.

1. Nutritional conditions

Artificial cultivation relies on the growing medium to provide nutrients for growth, so the medium needs to be selected. Generally, sawdust from hard broadleaf mixed wood is chosen to make the growing medium. Sawdust from coniferous trees is not suitable for cultivation. Wheat bran also needs to be added, as this can provide a source of vitamins and nitrogen. Some artificial nutrient preparations can also be added.

2. Temperature

The mycelium can generally grow above 4°C and below 32°C, but the most suitable range is between 22°C and 28°C. It is not tolerant of high temperatures, so above 30°C growth becomes very slow, and above 32°C growth may stop. It is more tolerant of low temperatures than other fungi, and can generally still produce mushrooms and form fruiting bodies below 15°C. So mushrooms can generally form at temperatures between 6 and 0°C.

3. Air and moisture

Nameko mushrooms are an aerobic edible mushroom and need frequent ventilation to release carbon dioxide from the shed and bring in fresh air. Carbon dioxide must not accumulate. Frequent ventilation is needed throughout the entire growth stage. As for moisture, the growing medium moisture for mycelial growth is generally around 60% to 65%, and the air humidity will naturally be fine; after fruiting bodies form, the moisture increases to around 70%, and the air humidity is above 80%. This is because the mycelium does not need that much moisture and is prone to oxygen deficiency, while after mushroom production more moisture is needed, so it is increased somewhat.

4. Light and pH

Mycelial growth likewise does not require light. During the fruiting body formation stage, some light is needed, which makes it easier to grow fruiting bodies. Diffused light is needed, and it cannot be completely dark and light-blocking; the light can be adjusted. The growing medium is suitable for growth in a slightly acidic medium, but it cannot be too acidic. Around 6.0 is best.

Pearl mushrooms are an aerobic edible mushroom. Cultivation requires adjusting temperature and humidity at every stage, and also maintaining relatively good air and moisture, as well as adjusting light. This achieves suitable environmental conditions.
