Abstract
The use of quadratic regression orthogonal rotation design,the effect of glucose,peptone,yeast extract,inorganic salts(MgSO_4,KH_2PO_4) on growth rate,dry weight of Pleurotus ostreatus.mycelium were studie.The result showed that glucose,peptone,yeast extract,inorganic salts of four components of Pleurotus ostreatus mycelia-speed effect of long-glu-cosepeptoneInorganic saltsyeast.Dry weight of mycelium of Pleurotus ostreatus effect for glucosesaltspep-toneyeast,hyphal length velocity was5.91 mm/d,dry weight of mycelium109.84 mg/total,with glucose 18.865～19.735 g/L,peptone 1.83225～1.98975 g/L,yeast extract,0.8685～1.6185g/L,salt 2.604-2.7000 g/L.
