通过改变温度、湿度、通风等条件设计5种北方黑木耳催耳芽处理方式,研究不同催耳芽处理方式与耳基形成、耳芽分化率和产量的关系。结果以菌床密集摆放,用塑料薄膜严盖,上盖草帘,于每天早7时、晚7时揭膜通风30分钟这一催芽方式较好,耳基形成较对照组早4天,耳芽分化率100%,子实体单片、厚实,较对照组出耳期缩短22天,产量提高18%以上。 Five kinds of treatment methods were designed by changing the temperature, humidity, ventilation and other conditions to study the relationship between ear bud formation, ear bud differentiation rate and yield. The results of densely placed bacteria bed, covered with plastic film, covered with straw curtain, every morning as early as 7 o’clock, 7 o’clock in the evening air exposed for 30 minutes, this germination is better, ear formation than the control group as early as 4 days, Ear bud differentiation rate of 100%, fruiting body monolithic, thick, shortened 22 days compared with the control group of the ear, the yield increased by 18%.
