Ashwagandha is an extremely aerobic mushroom, which needs more oxygen than other edible mushrooms, and the mushroom room needs to be ventilated 5-6 times a day. The mycelium growth stage requires less oxygen than the mushrooming stage, but it can't lack of oxygen, otherwise the mycelium will gradually weaken and shorten its life. In case of severe oxygen deficiency, mycelial growth will be hindered. Therefore, the mushroom shed should be ventilated frequently to keep the air fresh. Oxygen demand increases in the development stage of the mushroom, if the concentration of carbon dioxide in the air is high, it will affect the development of the mushroom, resulting in coral-like deformity, and in severe cases, the mushroom stops growing. Ashwagandha does not perform well in a corner position for mushroom production, and some varieties are not suitable for mushroom production indoors, such as Qianxi 1 and Xiaoheiting, and outdoor mushroom production also needs to be 2 to 3 meters away from high walls. Ashwagandha production sheds need to be kept continuously ventilated, except in windy weather, and generally 12 to 15 cm high vents should be maintained at the edge of the border field with 12 cm lying bricks, with one set up at two meter intervals. In order to verify the effects of temperature, humidity and ventilation on the development of ashwagandha mushrooms, Chen Guozhu et al. (1995) placed bags of mushrooms in three different humidity and ventilation environments to produce mushrooms after the buds had appeared and recorded the temperatures at 6 a.m. and 13 p.m. in the mushroom room on a day-by-day basis. The results (Table 8) showed that it was suitable to produce mushrooms from April to June, and the average temperatures at 6:00 a.m. and 13:00 a.m. were 20°C and 29°C. In late June, the temperatures at 6:00 a.m. and 13:00 a.m. were 24°C and 29°C on average, and the mushrooms were still able to grow normally. In early July, the average temperatures at 6:00 and 13:00 were 29℃ and 31℃, and the development of the mushroom body stopped, so it can be seen that high temperatures around 30℃ must be avoided during the cultivation period of the ashwagandha. Conditions of high humidity and poor ventilation are not favorable for mushroom development.
