Abstract:
Taking Lyophyllum decastes as material,effects of four inorganic salts and their orthogonal combination on the mycelial growth of Lyophyllum decastes were investigated by L9(34) orthogonal design on the PDA culture medium in this study，it could provide the theoretical basis of its high quality cultivation.The results showed that the best concentration on optical mycelia germination and growth of Lyophyllum decastes was ZnSO4 2.0 g/L，MgSO4 4.0 g/L，KH2PO4 4.0 g/L，FeSO4 1.5 g/L.ZnSO4，MgSO4，KH2PO4 and FeSO4 at high concentration could inhibit the mycelia growth，and mycelium could stop growth at a concentration of MgSO4≥10 g/L.The cooperative effects of four inorganic salts on the mycelial growth showed the impact order was FeSO4>MgSO4>KH2PO4>ZnSO4.Mycelial growth rate revealed that each combination had a highly significant difference and significant interaction.The best combination for the mycelia growth of?Lyophyllum decastes was 2.0 g/L ZnSO4+6.0 g/L MgSO4+6.0 g/L KH2PO4+1.0 g/L FeSO4.
