Abstract:: Taking Pleurotus eryngii as material,the screening and optimizing of liquid spawn medium of Pleurotus eryngii in submerged culture with shake flask were studied according to the indexs of mycelial dry weight,mycelial density,mycelial germination time and the fungus ball diameter.The results showed that the optimum formula for liquid spawn medium of Pleurotus eryngii was glucose 10 g/L，peptone 5 g/L，soybean bread flour 60 g/L，KH₂PO₄ 0.5 g/L，MgSO₄ 0.5 g/L，VB₁ 0.01 g/L，the mycelium of the formula had abundant biomass,high density,short germination time and appropriate diameter.
