金针菇是一种木腐菌,它能利用木材中的单糖、纤维素、木质素等化合物。但分解木材的能力较弱,坚硬的树木砍伐之后,没有达到一定的腐朽程度长不出子实体。陈旧的阔叶树木屑,经堆积发酵,部分分解的更适合金针菇的生长。1.碳源金针菇所需要的碳素营养都来自有机碳化合物,如纤维素、木质素、淀 Flammulina velutipes is a wood-rot fungus that uses compounds such as monosaccharides, cellulose and lignin in wood. However, the ability to decompose wood is weak. After hardened trees are cut down, they do not reach a certain level of decay and do not grow in the same way. The old hardwood chips, by the accumulation of fermentation, some decomposition is more suitable for the growth of Flammulina velutipes. 1. Carbon source Flammulina need carbon nutrients are derived from organic carbon compounds, such as cellulose, lignin, the lake
