新疆绿洲生态区袋栽黑木耳催耳芽技术

【目的】开发有效的袋栽黑木耳催耳芽方法,为袋栽黑木耳栽培提供理论基础和技术支持。【方法】 采用小孔出耳和集中催芽方法,对菌床菌袋的不同遮盖物和通风方式进行对比试验。【结果】主动通风和保湿性好的催芽方式出芽率最高,为93.28%;自然通风和具有一定保湿性的催芽方式出芽率也较高,可达80%以上;而通风差,保湿性好的催芽方式出芽率最差,在45%以下,且污染率和烧菌程度高。【结论】袋栽黑木耳催耳芽效果受湿度、温度、通风等多个因素的影响,在温度、湿度适宜的条件下,通风流畅可以明显提高出芽率和整齐度,降低污染率和烧菌程度。

Research on Pregermination Techniques of Auricularia auricula in Plastic Bag in Xinjiang Oasis Ecological Region

【Objective】 To develop an effective pregermination method of inducing ear bud in plastic bag culture of Auricularia auricular, and to provide theoretical basis and technical support for cultivation of Auricularia auricular.【Method】A comparative experiment was conducted on different covers and ventilation methods of mushroom bags in bacteria bed by using the method of perforated ear and concentrated germination.【Result】The germination rate of the active ventilation and moisturizing method was the highest, which was 93.28%. The germination rate was high in the case of natural ventilation and good humidity, which was over 80%. However, the sprouting rate was the worst in poor ventilation but good humidity condition, which was below 45%, and the pollution rate and the degree of burning bacteria were high.【Conclusion】Humidity, temperature and ventilation affect the pregermination effect of Auricularia auricula in plastic bags. The good ventilation could improve the germination rate and uniformity obviously and reduce the pollution rate and burning degree under the suitable temperature and humidity conditions.
