Abstract: In this paper, mycelial dry weight of mycelium and DNA content of Volvariella volvacea were determined to detect the effect of different concentrations of sodium acetate on mycelial biomass of V. volvacea. The results showed that with the increase of concentration of sodium acetate, mycelial biomass increased linearly. When the concentration reached 0.7 g·L-1, the biomass reached the peak, and the content of DNA was 468.9 ±4.10 μg·g-1, which was significantly higher than that of CK. While the concentration of sodium acetate was 0.9 g·L-1 and 1.1 g·L-1, the biomass decreased, but higher than that of CK. It was concluded that the suitable concentration of sodium acetate can significantly increase the mycelium dry weight of V. volvacea. Based on the optimal concentration of sodium acetate (0.7 g·L-1), the effect of Cu, Zn, K, Mn element and compound trace element on mycelia biomass were compared. The results showed that K and Cu element showed good effect, the mycelial biomass under all concentrations increased. Compared with CK, when the application amount of KH2PO4 was 8 g·L-1, the mycelial biomass was significantly increased by 84.32% (P<0.05); when the application amount of CuSO4 was 0.04 g·L-1, the mycelia biomass was significantly increased by 73.19% (P<0.05); when the application amount of ZnSO4 were 0.25 g·L-1 and 0.20 g·L-1, the mycelia biomass was increased by 42.69% and 20.34%, respectively; when the application amount of MnSO4 was 0.35 g·L-1, the mycelia biomass was increased by 25.23%. The Zn element and Mn element showed no significant effect on mycelium biomass with CK.
