Abstract:
Using the liquid vibration culture,the effect of trace element mixture on growth of several kinds of fertilizer microbes was studied. The results indicate that the growthes of Azotobacter chroococcum, Bacillus megatherium, B.mucilaginosus and Streptomyces microflavus are suppressed respectively when the total concentrations of MnCl2·4H2O、H3BO4、ZnSO4·7H2O、CuSO4·5H2O、Na2MoO4·H2O reach 1.00 g/L. However, the growthes of these fertilizer microbes are obviously promoted when the total concentration is 0.01 g/L.
