用木屑制香菇木耳原种,菌丝分解木屑很快,保种易老化。1977年,我们改用硬质木块作培养基接种,保存香菇、木耳种、效果较好。此后,又用木麻王树的干果制原种,效果也很好。3月接种,保存到10月移接栽培种,用木块、硬果做原种的,成活率均在99%以上,而木屑原种只成活40%。 Sesame mushrooms fungus species, mycelium break down sawdust quickly, easy to seed aging. In 1977, we switched to hardwood for medium inoculation, preserved mushrooms, fungus species, the effect is better. Since then, with the dried tree of the original plant species, the effect is also very good. Inoculated in March, preserved until October transplanting cultivars, with wooden blocks, hard fruits to do the original species, the survival rate was above 99%, while the sawdust species only survive 40%.
