近来用塑料袋制种或直接将塑料袋作为栽培容器进行熟料栽培食用菌的研究,发展十分迅速。为了满足季节性大生产的突击需要,常采用常压灭菌方法。影响常压灭菌效果因素有: 一、培养料预湿是否彻底用发酵过的粪草制作蘑菇塑料袋栽培种时,经常压灭菌、接种、培养十余日之后,常从袋中颗粒处暴出杂菌。除了因袋子被刺破、灭菌不彻底、灭菌时间过短有关之外,还跟培养料事先预湿不足有关。如粪草不经过预湿或预湿时间过短时,内部仍然呈干燥状态,致使湿热蒸气不能穿透到粪块中间,达不到彻底灭菌目的。因而粪草培养基配制时,粪块尽可能 Recently, plastic bags or plastic bags directly used as cultivation containers for cultivation of edible mushrooms, the development of very rapidly. In order to meet the needs of seasonal large-scale assault, often using atmospheric sterilization method. Affect the atmospheric sterilization factors are: First, the training material pre-wet Whether to use fermented dung to make mushroom plastic bag cultivation, the pressure sterilization, vaccination, training more than ten days, often from the bag particles Outbreak of bacteria. In addition to the bag was punctured, sterilization is not complete, sterilization time is too short, but also with the training material pre-wet less relevant. Such as dung without pre-wetting or pre-wetting time is too short, the interior is still dry, resulting in hot and humid vapor can not penetrate into the middle of fecal block, not up to the goal of complete sterilization. Therefore, manure medium preparation, fecal material as much as possible
