黑木耳的生活能力较平菇弱,即使用熟料栽培,因其发菌慢,常遭杂菌污染。再就是采收第一潮耳后,极易发生暴发性绿霉污染。针对这些问题,江苏省滨海县食用菌技术研究所经过多年探索,总结出一套菌墙覆泥栽培黑木耳的高产新技术。应用该技术栽培1 000千克料的黑木耳,在室温下发菌时间45天,污染率仅0.5%,生物效率达120%以上。黑木耳菌墙覆泥高产栽培技术要点如下:1.适时制种原种培养基配方为:棉籽壳 Black fungus living more weak mushrooms, that is, the use of clinker cultivation, due to its slow onset of bacteria, bacteria often contaminated. Then there is the first ebb ears after harvest, prone to outbreak of mold pollution. In response to these problems, Binhai County, Jiangsu Province, Institute of Edible Fungi after years of exploration, summed up a set of bacteria wall black fungus cultivation of new high-yielding new technology. Application of the technology to cultivate 1 000 kg of black fungus material, at room temperature germicidal time 45 days, the pollution rate was only 0.5%, the biological efficiency of 120% or more. Black fungus wall mulch high-yielding cultivation techniques are as follows: 1 timely seed production of the original medium formula: cotton seed hulls
