一、菌丝生长缓慢萎缩。菌种播后6～10天,有时出现菌丝生长缓慢甚至萎缩。其原因是由于气温过高,加上发酵料温度达30℃发上,抑制了菌丝的生长,导致菌丝烧死;或因料内含水多且又压得太实,空隙少,通气差,底层料内二氧化碳含量过高而造成。这时,应加强通风换气,降低湿度,并将过紧培养料适当撬松些。 First, mycelial growth slowed down. 6 to 10 days after sowing, sometimes mycelial growth slow or even shrink. The reason is due to the temperature is too high, with the fermentation material temperature up to 30 ℃ hair, inhibiting the growth of mycelium, resulting in mycelium burned; or because the material containing water and pressed too hard, less voids, ventilation Poor, the underlying material caused by high levels of carbon dioxide. At this time, ventilation should be strengthened to reduce humidity, and will be too tight training material appropriate pry more.
