| 摘 要： | 通过在泥鳅(Misgurnus anguillicaudatus Cantor)养殖水体中施加一定浓度梯度枯草芽孢杆菌(Bacillus subtili Cohns),测定了水化学指标并观察泥鳅生长情况。试验结果表明:枯草芽孢杆菌能够稳定养殖水体的pH值,对CODMn、TN和NO3--N降解极为显著,其降解速率分别为1.2、0.24和2.7g·L-1·d-1,TP在一定范围内波动;当菌液浓度大于149mL·L-1时,随着浓度的增加,停食后的泥鳅体重变化减小,因此,枯草芽孢杆菌对泥鳅养殖池塘水水质改善效果明显。

| Abstract: | The chemical indicators of water were determined and the growth of loach (Misgurnus anguillicaudatus Cantor) was observed after applied Bacillus subtilis in the loach culture water. The results showed that Bacillus subtilis could stabilize the pH of culture water, and remove COD_(Mn), TN and NO_3~--N obviously with the degradation rate of 1.2, 0.24 and 2.7 g·L~(-1)·d~(-1). TP fluctuated in a certain range. When the concentration of Bacillus subtilis was higher than 149 mL·L~(-1), the change of loach weight decreased with the increasing of concentrations. Therefore, the water quality of loach culture pond was improved obviously. |
