黑木耳正常情况下应出4茬耳,但目前有些头茬耳采收后,没等2茬耳长出就感染了杂菌,造成2~4茬耳产量降低,甚至绝收,影响了效益。江苏省滨海县食用菌栽培技术研究所经过多年实践,找出了黑木耳易受杂菌污染的原因,探索出一套黑木耳防污染多茬高产栽培新技术,使杂菌的污染率下降到最低,污 Black fungus should be 4 stubble under normal circumstances, but some of the first stubble after harvest, did not wait for 2 stubble out of infection on the bacteria, resulting in 2-4 stubble yield reduction, or even close, affecting the efficiency. Binhai County, Jiangsu Province, after years of practice of edible fungi cultivation practice to identify the black fungus susceptible to bacterial contamination of the reasons to explore a set of black fungus anti-pollution crop high-yielding cultivation of new technologies, the contamination rate of bacteria decreased to The lowest, dirty
