短木段熟料栽培黑木耳技术,是在传统段木栽培木耳技术的基础上,对木段进行高温灭菌处理,其工艺是:将准备好的段木截成12cm长短木段,套聚丙烯塑料筒,蒸汽灭菌,接种,室内菌丝培养,室外脱袋出耳,采收。与传统段木栽培法相比,增加了截断、套袋、灭菌、脱袋四道工序,但少了上堆发菌、散堆排场、起架管理三个劳动强度大的工序。 实践表明,一根直径1Ocm、长12cm的短木段,熟料栽培可产干耳50g,而一根直径1Ocm、长2m的段木,传统栽培最高产干耳380g,平均12cm长木段产干耳仅22.8g,产量明显低于短木段熟料栽培法。分析其高产原因:①木段经高温灭菌,杂菌被杀死,减少了木段营养的损失;②木段经高温熟化,营养物质外溢,等于增加了木耳利用率最高的边材营养,③室内培养,温度、湿度、光线可控制在菌丝生长最适范围,菌丝生长健壮,增强了抗性。该技术在白石山林业局琵河林场应用三年,取得了较好的经济、生态和社会效益,并为森 Shortwood clinker cultivation black fungus technology, is based on the traditional section of fungus cultivation of fungus technology, high temperature sterilization of wooden sections, the process is: the prepared section of wood cut into 12cm length wood section, sets of poly Acrylic plastic tube, steam sterilization, inoculation, indoor mycelium culture, outdoor Shou Dai ears, harvesting. Compared with the traditional segment cultivation method, truncation, bagging, sterilization and bag removal are added. However, there are fewer processes with high labor intensity, such as stacking of bacteria, random stacking, and frame management. Practice shows that a diameter of 1Ocm, 12cm long short pieces of wood, clinker cultivation can produce dry ear 50g, and a diameter of 1Ocm, 2m long section of the wood, the traditional cultivation of the highest yield dry ear 380g, an average of 12cm long section of wood production Dry ear only 22.8g, the yield was significantly lower than the short block clinker cultivation method. Analysis of the reasons for its high yield: ① high temperature sterilization wooden section, the bacteria were killed, reducing the nutritional loss of wooden section; ② high temperature aging of wood, nutrient spills, equal to increase the fungus utilization of the highest sapwood nutrition, ③ indoor training, temperature, humidity, light can control the optimum range of mycelium growth, mycelium robust growth, enhanced resistance. The technology in Baishishan Forestry Bureau Pihe Forest Farm for three years and achieved good economic, ecological and social benefits, and Sen
