在草菇栽培试验和生产过程中,常可见到成片的小菇萎蔫而死亡。本文根据笔者的实践和调查资料,就其死菇原因和防止措施,浅析如下。(一)通气不良草菇是高温型好气性真菌,生长发育过程需要足量的氧气,但由于在栽培过程中为了提高堆温,有时薄膜覆盖时间过长,结果料堆中的二氧化碳过多而导致缺氧,即使已揭开薄膜,小菇仍因通气不良,排气不畅,难以正常长大而萎蔫.因此,在播种4天内,要注意定时小通风(每天约半小时),4天后揭去薄膜时要用小竹棍向料堆均匀戳些通气孔,促使菌丝正常结蕾,小菇正常长大;室内栽培每天要注意定时通风。 Mushroom cultivation in the test and the production process, can often be seen into pieces of small mushroom wilt death. This article based on the author’s practice and investigation of information on the causes of their mushrooms and prevention measures, as follows. (A) poor ventilation Straw mushroom is a high-temperature aerobic fungi, the growth and development process requires sufficient oxygen, but due to the cultivation process in order to improve the reactor temperature, sometimes the film covering time is too long, the results of the pile of carbon dioxide too much Leading to hypoxia, even if the film has been opened, mushroom is still due to poor ventilation, poor exhaust, difficult to grow normally and wilting.Therefore, within 4 days of planting, pay attention to regular small ventilation (about half an hour a day), 4 days Uncover the film with bamboo sticks to the heap even stab some vents, to promote normal mycelium knot bud, mushroom normal growth; indoors cultivation should pay attention to regular ventilation.
