有益微生物对中华鳖养殖池塘水质及细菌数量的影响
Effects of Beneficial Microbes on the Water Quality and Bacteria Quantity in the Pond of Pelodiscus sinensis
摘要
Abstract
The research aimed to study the effects of applying Bacillus subtilis, Lactobacillus plantation and the mixture of these two microbe by the in equal ratio on the water quality and total amount of heterotrophic bacteria in the culture pond of Pelodiscus sinensis. [ Methodj 1 mg/L Bacillus subtilis, 1 mg/L Lactobacillus plantarum and the mixture of 0.5 mg/L B. subtilis and 0.5 mg/L L. plantarum were applied in the test ponds to study its effects on the nitrite content, ammonia nitrogen content, dissolved oxygen content, pH and total amount of heterotrophic bacteria in the water body in the culture pond of Pelodiscus sinensis. [ Result ] Applying these beneficial microbes had no significant effect on dissolved oxygen and pH in the culture water body. The mixture had the most obvious removal effects on ammonia nitrogen and nitrite in culture water body and trie contents of ammonia nitrogen and nitrite decreased 42.37% and 45.56% respectively. The removal rates of B. sublilis and L. plantarum was the next,which decreased the contents of ammonia nitrogen and nitrite 34. 60% and 31. 63% , 14. 54% and 15. 59% respectively. The total amount of heterotrophic bacteria in the test groups of adding B. subtilis and L. plantarum and the mixture and control group were 3. 02 x 105,3.09 × 105,3.13× 105 and 3.45× 105 cfu/ml respectively and there was no significant difference among the test groups(P <0.05). [Conclusion] Applying this mixture could effectively improve the water quality,and the total amount of heterotrophic bacteria in the water body was the lest.关键词
