蘑菇栽培中,通常有12～15种霉菌不被看成是引起病害的祸手,这并不意味着这些霉菌应该受到欢迎。尽管它们的存在不直接带来危害,我们也不能因此掉以轻心。蘑菇菌床上的任何霉菌,在某种程度上都可能与蘑菇争夺养料、水分和空间,某些霉菌也许正产生某些物质促进另一些蘑菇病原菌生长,或以某种方式影响蘑菇生长。事实上,有的霉菌或许正抵抗蘑菇病原菌,这是一种生物防治。但在没有相反的证据时,最好不要把霉菌往好处看,今天一小块毫不起眼的霉斑,明天可能发展成数个明显的斑块。虽然没有必要把这些霉菌看成完全有用, Mushroom cultivation, usually 12 to 15 kinds of mold is not seen as the cause of the disease, this does not mean that these mold should be welcomed. Although their existence does not directly bring harm, we can not therefore take it lightly. Any fungus on a mushroom bed may to some extent compete with the mushroom for nourishment, moisture and space, and some fungi may be producing something to promote the growth of other mushroom pathogens or in some way affect mushroom growth. In fact, some mold may be resistant to mushroom pathogens, which is a biological control. But in the absence of evidence to the contrary, it is best not to look at the benefits of mold. Today, a small piece of obscure mildew can develop into obvious plaques tomorrow. Although it is not necessary to think of these molds as completely useful,
