用棉籽壳栽培平菇和凤尾菇时,经常出现菌种播后料面局部或大块的菌种不萌发。据观察,这种现象的主要原因是薄膜封盖太严密,引起培养料发酵产生的废气积聚氧气不足所致。若不及时处理,将会导致严重减产。自1985年以来,笔者在栽培和辅导生产的过程中,对上述出现情况采取以下方法进行处理,收到了明显效果。1.播种后,用木棒、竹签或菌种瓶撑起薄膜,薄膜边缘切忌扎紧,使膜内有足够空间进行气体交换,为菌种萌发创造一个良好的供氧环境。
With cottonseed shell cultivation Pleurotus ostreatus and Pleurotus ostreatus, it is not uncommon for bacteria to grow locally or chunky after sowing. It is observed that the main reason for this phenomenon is the film sealing is too tight, causing the culture material fermentation exhaust gas accumulation due to lack of oxygen. If not handled in time, it will lead to serious cuts. Since 1985, in the process of cultivating and counseling the production, the author has taken the following measures to deal with the above situations and has received obvious effects. 1. After sowing, stick with sticks, bamboo sticks or strain bottles propped up the film edge should not be tight, so that there is sufficient space for gas exchange membrane for the germination of bacteria to create a good oxygen environment.
