Tea Tree Mushroom Cultivation Technology（1）

The growth environment requirements of Agrocybe agrocybe are as follows:

1. Nutrition
Agrocybe aegerita belongs to wood-decomposing fungi. Mycelium has a strong ability to utilize cellulose, but a weak ability to utilize lignin. It has a good utilization of organic nitrogen. When cultivated artificially, protein-rich raw materials such as rice bran, wheat bran, corn flour, and various cake flours are added to the culture medium to facilitate the growth of mycelium and shorten the fungus cycle.

2. Temperature
Agrocybe aegerita belongs to a mesophilic constant temperature fruiting fungus. The mycelium growth temperature is 5~34℃, and the suitable temperature is 24~28℃; the suitable temperature for fruiting body differentiation is 18~22℃, and the requirements for differentiation temperature are different for different varieties; the fruiting body growth temperature is 10~30℃, and the suitable temperature is 20~25℃. Primordial differentiation does not require temperature difference stimulation or low temperature stimulation, but culturing at a lower temperature for a period of time and then transferring to 18~25℃ for cultivation can make the mushrooms uniform and improve the commerciality of the fruiting bodies.

3. Moisture and Humidity
Mycelium grows faster when the moisture content of the culture medium is 65%~70%. During the growth of mycelium, the relative humidity of the air is preferably 60%~70%; during the fruiting body growth stage, 85%~90% is appropriate. If the humidity is too high, the cap will easily open, and if the humidity is too low, the mushroom body will shrivel and growth will be hindered.

4. Air
Agrocybe aegerita is an aerobic fungus. There should be sufficient oxygen during the spawning and fruiting stages. If the ventilation is poor, the mycelium will grow very slowly and the primordium will differentiate slowly. However, Agrocybe aegerita is a stalk-eating fungus. Properly increasing the carbon dioxide concentration in the mushroom house during the fruiting body growth stage will form high-quality commercial mushrooms with long stalks and small caps.

5. Light
Agrocybe aegerita is a photophilic fungus. Mycelium growth does not require light. During the fruiting body growth period, 250~500lx of scattered light is required. Insufficient light will result in slow fruiting, light-colored fruiting bodies, and long mushroom feet. The fruiting bodies of Agrocybe aegerita have obvious phototropism. The direction of the light source cannot be changed at will during cultivation to avoid deformed mushrooms.

6. PH Value
Agrocybe aegerita prefers an acidic environment. Mycelium can grow in the pH range of 4 to 7, and the most suitable pH is 5.5 to 6.5. Agrocybe aegerita produces very little organic acid during the fruiting process, so the pH on the surface and inside of the mushroom medium does not change much, and is usually maintained at pH 5.77 to 5.87. The pH required for primordium differentiation and fruiting body growth and development is generally 5.0 to 6.0.
