| 摘要: |
| 监测了施用芽孢杆菌(Bacillus sp.)后的养虾池水体和底泥总异养细菌和弧菌数量以及水体浮游微藻数量的变化,分析了应用芽孢杆菌对养殖环境微生态的影响。结果表明,芽孢杆菌对虾池水体的异养细菌和弧菌生长和繁殖具有一定的抑制作用,对底泥异养菌和弧菌具有一定的促进作用,能促进浮游微藻的平稳繁殖。芽胞杆菌通过这些作用抑制了水体中条件致病菌的繁殖,促进了虾池物质和能量的循环,有利于虾池的自我净化。 |

| Primary study on mediating micro-ecological environment with Bacillus sp. in shrimp pond |

| Abstract: |
| The influence of Bacillus sp. utilization on a micro-ecological environment in shrimp pond was studied primarily by detecting the changes of phytoplankton, heterotrophic bacteria and Vibrio in the pond water and sediment. The results showed that Bacillus sp. could inhibit the growths of heterotrophic bacteria and Vibrio in the pond water while it enhances those of the heterotrophic bacteria and Vibrio in the sediment to a certain extent, and promotes the consistent reproduction of the phytoplankton. So, the utilization of the Bacillus sp. could reduce the opportunistic pathogens and promote the cycles of the material and energy, which would be favorable to the self-cleaning of the shrimp pond. |
