The impacts of inorganic salts and growth factors on the growth of Agaricus bisporus strain and strain in liquid medium were studied.The results showed that 0.1% KH2PO4 and MgSO4 in the medium could promote the growth rate of Agaricus bisporus strain.0.15 μg/ml Vc,0.15 μg/ml VB1,0.1 μg/ml VB6 and 0.05 μg/ml VB7 was beneficial for the growth of strain in agar medium.In addition,the mixture of 0.05 μg/ml Vc,0.1 μg/ml VB1,0.1 μg/ml VB6 and 0.1 μg/ml VB7 was added to the liquid medium,which could promote the gr...
