菌种瓶用棉塞封口，成本较高，并且棉花容易污染，再利用性也较差。利用塑料代替棉塞，虽然降低了成本，但是因为塑料透气性差，供氧不足，菌丝生长迟缓，柔弱纤细，还导致嫌气性杂菌生长。在黑木耳育种过程中，用九层纱布封口，菌丝生长迅速，洁白粗壮，又不发生污染，而且简
Seeds bottle sealed with a tampon, high cost, and cotton easily contaminated, re-use is also poor. The use of plastic instead of tampons, although lower costs, but because of poor plastic breathability, lack of oxygen, mycelial growth retardation, weak and slender, also led to the growth of anaerobic bacteria. In the black fungus breeding process, with nine layers of gauze seal, mycelium grow rapidly, white thick, without pollution, and Jane
