人防地道中栽培平菇常出现花椰菜花球型、珊瑚型及柄长盖小的高脚型三类畸形菇,对产量影响较大。在适宜于平菇子实体形成的气温条件下,它们分别由 CO_2浓度过高或光照度不足或两者兼备的因素引起。调查及试验证明,菇床表面保持光照度4～10Lux 及 CO_2浓度1,000ppm 左右,平菇子实体可以正常形成。在通风条件好的人防地道中,床面光照度只需1～3 Lux。因此,目前用于栽培平菇的多数人防地道,光照度配置不当,可较大幅度降低,以节约用电,降低成本。
Civilian civilians in the cultivation of mushrooms often appear cauliflower flower ball, coral and stem long cover small tall three types of mushroom, a greater impact on the yield. Under suitable temperature conditions for the formation of Pleurotus ostreatus fruiting bodies, they are caused by factors such as high CO 2 concentration or insufficient illumination or both. Investigation and test proved that the mushroom bed surface to maintain the illumination 4 ~ 10Lux and CO 2 concentration of about 1,000ppm, Pleurotus fruiting bodies can be normal. In well-ventilated civil air defense, the bed illumination only 1 ~ 3 Lux. Therefore, most of the current civil air defense cultivation for mushroom cultivation Road, light intensity configuration properly, can be significantly reduced in order to save electricity and reduce costs.
