Biological characteristics and production mode of Oyster mushroom

Biological characteristics of Oyster mushroom

Oyster mushroom is a mesophilic edible fungus, wood-decomposing nutrition type. The optimum 

growth temperature of mycelium is 25~28℃, the temperature of fruiting body is 15~21℃, and the 

carbon dioxide concentration is controlled at 0.2%. The relative humidity of air is controlled at 60%~65%

 during the spawning stage, and 85%~90% during the fruiting stage. 

Production mode

According to the cultivation mode, the vast majority of China's Oyster mushroom production is still 

agricultural production, and a few have achieved factory production. Due to the impact of agricultural 

production, the factory production of Oyster mushroom has not yet achieved year-round production.

 According to the cultivation container, my country uses plastic bags for cultivation, and there is no 

bottle cultivation. Japan and South Korea use bottle cultivation. According to the culture medium 

treatment method, it is divided into: raw material cultivation, fermented material cultivation and

 cooked material cultivation.

For Oyster mushroom, the advantages of bag cultivation are more tides and high yields. The specifications

 of the cultivation bag are one of the important factors affecting the yield. The advantages of bottle cultivation

 are high consistency of mushroom production, easy management, and suitable for factory cultivation. 

The above picture shows grid cultivation. The light-induced mushroom buds are neat. The reflection on

 the ground is the presence of a water film, which increases the relative humidity of the air and ensures

 that the mushroom buds develop normally into commercial mushrooms.

Regarding the processing methods of culture media, there are mainly three types: raw materials, fermented 

materials, and cooked materials. Raw material cultivation has been almost eliminated due to serious pollution

rates and pests and diseases. For agricultural production, fermented materials or cooked materials can be selected 

according to the season. Some areas have tried to ferment for a short time before sterilization, but this technology

is affected by the season and raw materials and is not yet mature. Factory cultivation must use cooked materials.
