II. The life characteristics of Jade fungus

1. Temperature: temperature is an important factor in the growth and development rate and life activity intensity of left and right Auricularia auricula. Auricularia auricula is a medium-high temperature fungus, its spore germination temperature is in the range of 22-32 ℃, and 30 ℃ is the most suitable. The mycelium could grow between 8 and 36 ℃, but the suitable one was 22 to 32 ℃. When the mycelium was below 8 ℃, the mycelium was inhibited above 38 ℃. The mycelium of Auricularia auricula is resistant to high temperature but not to low temperature. The mycelium of Auricularia auricula can be killed at low temperature for a long time, so the preservation temperature of Auricularia auricula should be above 8 ℃. Auricularia auricula belongs to thermostatic fruiting fungi. The temperature required for the fruiting body is lower than that of the mycelium. The mycelia of Auricularia auricula could differentiate into fruiting bodies under the condition of 15: 32 ℃, and the optimum temperature for growth was 20: 28 ℃. More than 38 ℃ was inhibited. Lower temperature leads to slow growth and development, long growth cycle and strong mycelium, and the fruit body is white and thick in the suitable temperature range, which is beneficial to obtain high-yield and high-quality Auricularia auricula; the higher the temperature, the faster the growth and development, the mycelium grows easily to senescence, the fruit body is thin and poor meat quality.

2. Moisture and humidity: water is an important component of Auricularia auricula, which can also promote the metabolism of Auricularia auricula and help it absorb nutrients. Auricularia auricula needs water at all stages of growth and development. A large amount of water is needed during the development of fruiting body. The spore germination of Auricularia auricula needs water. The germination time was longer on solid medium. The water content of conventional medium can meet the requirement of water content during spore germination.

Most of the water needed for the growth and development of Auricularia auricula comes from the culture material, and the water content of the culture material is an important factor for the emergence of auricularia auricula. The colonization and spread of Auricularia auricula in the mycelium; the water content of the culture material during the growth period should be 60%-70%. Too little water affects the absorption and utilization of nutrients and reduces the vitality of mycelium; too much water leads to poor air permeability and lack of oxygen inhibits the growth and development of mycelium and may even suffocate to death. During the period of fruiting body formation, the requirement of humidity is relatively strict. In addition to the culture medium requiring water content of 70%, the air relative humidity is also required to be kept at 90%-95%. This can promote the fruiting body to grow rapidly, with big ears and thick flesh. Less than 80% of the fruiting bodies are slow or even difficult to form.

3. Lighting: different developmental stages of Auricularia auricula have different requirements for light. Mycelium can grow normally in dark or scattered light environment. Light can promote the transformation of Auricularia auricula from vegetative growth to reproductive growth, which may be related to the light induction or activation of enzymes in the physiological transformation of fungi. It is difficult for Auricularia auricula to form a fruiting body in a dark environment, and only with a certain amount of scattered light can a strong fruiting body be grown. However, Auricularia auricula does not like direct light, which is easy to affect the quality of Auricularia auricula.

4. Air: Auricularia auricula is an aerobic fungus. Its respiration is to absorb oxygen and release carbon dioxide. When the carbon dioxide in the air exceeds 1%, it will hinder the growth of the mycelium, and the fruiting body will become deformed into coral, often without opening; more than 5% will lead to the poisoning and death of the fruiting body. Therefore, in the whole process of growth and development of Auricularia auricula, the cultivation site should keep the air fresh. In the production of bacteria, the moisture of the culture material should not be too much, and the bottle should not be too full, so as to provide the necessary oxygen to the mycelium. In addition, fresh air can also avoid rotten ears and reduce the breeding of diseases and insects.

5. PH: Auricularia auricula is suitable to live in a slightly acidic environment. The mycelium could grow normally in the range of pH4~7, and pH5~6.5 was the most suitable.

The above is the introduction of the planting method of Auricularia auricula. Auricularia auricula belongs to constant temperature fruiting fungi. Temperature is an important factor in the speed of production and development and the intensity of life activities of left and right Auricularia auricula. The lower the temperature is, the slower its growth and development is, and the higher yield and quality can be obtained.
