香菇烂筒病及其病因研究初报

本文报道了香菇烂筒病的发生情况、症状及病原体的鉴定。笔者在福建省不同地方调查了早、中、晚期发病且症状明显的菇筒,分离、培养、鉴定了病原,并作回接发病试验,证实土壤中的木霉(Trichoderma spp.)是引起烂筒病的重要病原。

A Preliminary Study on the Rotten Substrate Bag Disease of Lentinula edodes and Its Causal Pathogens

The ocurrence, symptoms and pathogens of rotten substrate bag disease of Lentinula edodes were reported in this paper. The rotten substrate bags occurred at early, middle or later cultivation periods with obvious symptoms were collected from different places in Fujian Province, and the pathogens of the rotten substrate bags were isolated and cultured for identification.
