一.蘑菇轮枝菌病害的特点蘑菇床上发生的杂菌,经回接试验发现,一类只是占据蘑菇的生长空间,夺取培养料中的营养物质,使蘑菇生长衰弱,甚至不长,造成蘑菇减产;另一类则属病原菌,它直接侵害菇体.1980年开始,我们先后从病菇与菇床上分离出294株轮枝菌及其近似属,经健菇回接试验,发现能感病的169株,占57.5%,无感病的125株. A characteristic of mushroom disease Vertebrate mushroom bacteria occurred on the bed, the back connection test found that only occupy a class of mushroom growth space, to seize the nutrients in the culture material, so that weak mushroom growth, or even not long, resulting in mushrooms Reduce production; the other is a pathogenic bacteria, which directly infringe the mushroom body .1980, we have from the mushrooms and mushroom bed separation of 294 strains of Verticillium and its genus, the mushroom back connection test found that flu Of 169 strains, accounting for 57.5% of the non-susceptible strains of 125.
