传统的知识认为,香菇(Lentinus edodes Benk Sing)菌丝体不能在杉树段木上生长。而我们的研究揭示了杉树段木可直接用于香菇的栽培,且香菇生产与段木床香精油含量密切相关。研究结果如下:(1)7—12树龄的杉树段木对香菇的生产最好;(2)段木顶部(近树冠)获得了较高的产量;(3)树木砍伐后,为了利于香菇生产,在接种前,把段木搁置林中80天或浸泡在水中3天;(4)菌丝接种最理想的钻孔距离是3～6cm;(5)在接种香菇菌丝后,为促进菌丝体的生长,最佳成熟期为6个月,而且在栽培期,段木床最佳倾斜角度小于45°;(6)在菌丝种植的段木床上生产的香菇收摘可达13次,最高的产量是第4～6次收摘期或在种植后9～11月中获得。
The traditional wisdom is that Lentinus edodes Benk Sing mycelia do not grow on cedar wood. Our research revealed that Cunninghamia lanceolata wood can be directly used for the cultivation of mushrooms, and the production of mushrooms is closely related to the content of essential oil in the wood block. The results are as follows: (1) Fir trees with ages of 7 to 12 were the best to produce mushrooms; (2) the top of the tree (near the crown) got higher yield; (3) Production, before inoculation, the section of wood shelved in the forest for 80 days or soaked in water for 3 days; (4) mycelium inoculation ideal drilling distance is 3 ~ 6cm; (5) after inoculation of mushroom mycelium, to promote Mycelium growth, the best maturity of 6 months, and in the cultivation period, the optimal tilt angle of the section of the wood bed is less than 45 °; (6) Times, the highest yield is the first 4 ~ 6 harvest received or 9 to November after planting obtained.
