摘要
对3种微生态制剂改善河蟹养殖池水质的效果进行分析比较。实验组各池中分别加入超浓缩光合细菌(PSB)、"西菲利"活菌生物净水剂、活菌净水剂以及3种微生态制剂组成的混合制剂。观察氨态氮、亚硝态氮、硫化氢、溶解氧、化学耗氧量、pH及异养菌总数等水质指标。结果表明:3种微生态制剂均能改善水质,抑制异养菌的过度增长,但对水质指标的改善各有侧重,混合制剂优于单一制剂。
The effects of three micro-ecological pharmaceutics in improving the water quality of Eriocheir sinensis cultrued pond were compared.The super-concentrated photosynthetic bacteria(PSB),the lived biological purifying agents(Xifeili),the lived microbial purifying agents and the compound micro-ecological pharmaceutics which comprise of the upper three agents were used in every experimental ponds.The NH+4-nitrogen,nitrite nitrogen,H2S,dissolved oxygen(DO),chemical oxygen demand(COD),pH and the quantities of hegerotrophic bacteria were observed.The results showed that all the three micro-ecological pharmaceutics could improved the water quality,and could inhibited the growth of hegerotrophic bacteria,but the three micro-ecological pharmaceutics have different effects in the water quality,the compound agents were better than the others.
