一、菌丝萎缩平菇播种后7～10天，有时会出现菌丝萎缩现象。这由于气温过高，加上料温高达30℃以上，造成菌丝烧死所致。应加强通风换气，降低温底和湿度。如培养料装得过紧，可将培养料撬松些。二、不现而菌丝长满后不出范。一是选用菌种不适宜，如春栽型选用了低温型品种，由
First, mycelium atrophy Pleurotus ostreatus after sowing 7 to 10 days, sometimes mycelial atrophy. This is due to the temperature is too high, with the material temperature as high as 30 ℃, resulting in mycelium burned. Ventilation should be strengthened to reduce temperature and humidity. If the material is too tight training materials, materials can be prized pine. Second, it does not appear after the mycelium covered. First, the selection of strains is not appropriate, such as the selection of the spring planting type of low temperature type, from
