为研究常见元素对榆木离褶伞菌丝生长的影响,通过其在含有不同离子浓度的PDA培养基中生长速度的观察,探讨不同元素及其浓度对榆木离褶伞菌丝生长的影响。结果表明:1 mg/mL的Mg(Ac)2、KH2PO4和CaO促进菌丝生长;5,10 mg/mL的Mg(Ac)2、CaO,10mg/mL的Na2SO4、NaCl抑制菌丝生长;其他种类及浓度的离子对菌丝生长的影响不显著。 In order to study the effect of common elements on the growth of Elsholtzia pleuromum, the effects of different elements and their concentrations on the mycelial growth of Pleurotus elm were studied by observing their growth speed in PDA medium containing different ion concentrations . The results showed that mycelial growth was promoted by Mg (Ac) 2, KH2PO4 and CaO at 1 mg / mL, Mg (Ac) 2 at 5 and 10 mg / mL, CaO at 10 mg / mL and Na2SO4 at NaCl concentration of 10 mg / The type and concentration of ions on the mycelium growth was not significant.
