以采自黑龙江省的5种大型真菌多脂鳞伞、豹皮新香菇、马鞍菌、晶粒鬼伞、绒白乳菇为试材,对子实体进行分离获得菌株,采用观察、测量、SPSS Statistics 17.0统计分析等方法,研究比较了4种不同水平的碳源、氮源、pH值对5个菌株菌丝生长速度及长势的影响。结果表明:每一种真菌都有其最适的碳氮源和pH值,分别筛选出了适宜5个菌株生长的最佳培养基。 Five species of large-scale fungi from the Heilongjiang Province were used to study the effects of five large-scale fungi, Scutellaria baicalensis, Lentinus edodes, Mycobacterium lemaneum, Statistics 17.0 statistical analysis and other methods to study the four different levels of carbon sources, nitrogen sources, pH value of the five strains of mycelial growth rate and growth. The results showed that each fungus had its optimum carbon and nitrogen sources and pH, and the best culture medium suitable for the growth of five strains was screened out.
