The latest course of cultivation techniques of Auricularia auricula

Auricularia auricula, also known as Auricularia auricula, Auricularia auricula, etc., is a fungus of Auricularia auriculaceae, which is distributed in most parts of China and grows on willow, acacia, mulberry and other tree trunks or rotten wood. Its nutritional composition is similar to that of black fungus, which has the effect of clearing lung and tonifying qi, relieving pain and promoting blood circulation. Let's take a look at the cultivation techniques of Auricularia auricula.

Cultivation temperature

Auricularia auricula is a kind of medium-high temperature fungus, the mycelium growth temperature range is ~ 37 ℃, the suitable temperature is 25 ~ 30 ℃, and the mycelium growth stops when it exceeds 40 ℃. The temperature of fruiting body is 18-34 ℃, and the most suitable temperature is 22-28 ℃. At this temperature, a large number of fruiting bodies occur with high yield and good quality, and the optimum temperature for basidiospore germination is 22-25 ℃.

Cultivation humidity

The mycelium growth of Auricularia auricula requires that the water content of the culture material is about 60%, and the air relative humidity is less than 70%. If the water content of the culture material is too high and the bottom of the material is stagnant, the mycelium grows slowly or stops growing. The fruiting body development stage requires higher air humidity, and the air relative humidity of the mushroom room should be 85% 95%. Under this humidity, the fruiting body develops rapidly, the ear plexus is large and the ear piece is thick. However, if the air humidity is too high, it is easy to be infected by miscellaneous bacteria and cause ear bleeding.

Air condition

Auricularia auricula is a kind of aerobic fungus. In the process of growth and development, the air in the culture room (shed) is fresh, the oxygen is sufficient, the mycelium grows well, and the fruiting body is easy to form, elongate and open. If poor ventilation, excessive accumulation of carbon dioxide, inhibition of mycelium and fruiting body growth, but also lead to miscellaneous bacteria pollution.

Light condition

The mycelium of Auricularia auricula generally does not need light in the growth stage, but needs some scattered light in the stage of primordium differentiation and formation. The intensity of light has a direct effect on the color quality of the earpiece. Under the condition of low light, the earpiece is light, short and fine. The light is strong, the ear piece is dark, and the hair is long and thick.

Acidity and alkalinity

The optimum PH for mycelial growth of Auricularia auricula was 6.0 to 7.5. When the pH was below 4.5 or above 8.5, the mycelium growth potential was weak and the growth rate was slow. During the fruiting body growth, the suitable PH was 5.2-8.0 and the optimum PH was 6.5-7.0.

Note: Auricularia auricula is a kind of middle and high temperature ear, which is cultivated in spring, the Summer Solstice, summer and autumn, with strong vitality, wide adaptability and strong anti-mildew ability. in addition, Auricularia auricula has strong alkali resistance, and the growth of miscellaneous bacteria can be inhibited by properly adjusting the PH of culture materials. next we will take a look at the cultivation techniques of Auricularia auricula.
