在生产香菇栽培种中,如何提高成品率,这是人们所关注的问题。笔者的实践和调查,目前制种成品率普遍较低,是由于链孢霭菌的污染。本文就如何防治链孢霉菌污染谈点看法,供同行们参考。首先,要预防棉塞受潮。引起链孢霉菌污染的关键是棉塞受潮,预防棉塞受潮要注意以下几点:①装袋时料不能装得太满,以免棉塞接触到料致使料中的水份被棉塞吸收而成湿棉塞。②高温灭菌时料袋最好套上牛皮纸袋,若不套纸袋则以横置为好。③灭菌锅的盖要做成弧形或维形,锅的内壁要做得光滑,使凝结水能沿边壁流下。④灭好菌待出锅前,先把门开小一些,借助内部热量蒸发纸袋和棉塞上的水份。⑤接种时如遇有湿棉塞,一定要更换干棉塞,这是制种过程中最后也是最关键的一关.
In the production of mushroom cultivation, how to improve the yield, which is a matter of concern. The author’s practice and investigation, the current rate of seed production is generally lower, due to the contamination of the filamentous fungus. This article on how to prevent streptomycin contamination point of view, for colleagues reference. First of all, to prevent tampons damp. Spore mold spores caused by fungus is the key to damp tamponade to prevent tampon damp should pay attention to the following points: ① bagging material can not be loaded too full, so that the tampon in contact with the expected material to make the water absorbed by the tampon Into a wet tampon. ② high temperature sterilization when the best kraft bag put on kraft paper bag, if not set of paper bag to horizontal as well. ③ sterilization pot lid to make a curved or dimensional shape, the pot wall to be made smooth, so that condensate can flow along the wall. ④ out of good bacteria to be before the pan, first open the door a little smaller, with the internal heat evaporation of paper and tampons on the water. ⑤ inoculation in case of wet tampons, cotton tampons must be replaced, this is the seed production process is the last and the most crucial level.
