线虫(Nematodes)是蘑菇生长后期的重要害虫。为害蘑菇的线虫由于虫体较小(一般长500～1000微米,宽20～50微米),肉眼不易观察,加上其为害的症状不易与生理性的菌丝萎缩相区别。因此,长期以来对由线虫引起蘑菇减产和品质下降没有引起人们足够的重视。我们对上海郊区的十个菇房春菇培养料进行抽样调查表明,所有的菇房都有不同程度的线虫发生,低产菇房尤为严重,现将调查结果报道如下。
Nematodes are an important pest in the later stages of mushroom growth. Nematodes damage mushrooms because of small parasites (usually 500 to 1000 microns long, 20 to 50 microns wide), the naked eye is not easy to observe, coupled with its harmful symptoms and physiological atrophy is not easy to distinguish mycelium. Therefore, for a long time by the nematodes caused by the mushroom yield and quality did not cause enough attention. We conducted a sample survey of 10 Mushroom Cultivation Materials in the suburbs of Shanghai. The results showed that all Mushroom Houses had different degrees of nematode occurrence and the low-yielding mushroom house was particularly serious. The survey results are reported as follows.
