开放式生产栽培种,即不是在瓶子等小容器里而是在平菇床上培养菌种是可行的,其原理是运用平菇菌丝体的拮抗作用,自然抑制其他杂菌生长。平菇菌丝体在与常见霉菌菌丝体共居的情况下,前者常以粗壮的菌丝束包围吞并后者,并杀死其菌丝体,最后长满整个培养料。除少数青霉、木霉等外,在感染霉菌的菌种瓶里可观察到这种拮抗现象。 Open-planted cultivars, that is, not in small containers such as bottles, but in the cultivation of mushroom strains of mushroom is feasible, the principle is the use of mushroom antagonistic effect of mycelium, natural inhibition of other bacteria growth. Pleurotus ostreatus mycelium living in common with the mycelium of the case, the former often surrounded by thick mycelium swallow the latter, and kill its mycelium, and finally covered with the entire culture material. In addition to a few penicillium, Trichoderma, etc., this fungal antagonistic phenomenon can be observed in mold-infected bottles.
