| 中文摘要: |
| 在测定养殖水体pH值、溶解氧、氨态氮、亚硝态氮等水质指标和养殖青虾肥满度、平均规格、饲料系数等生长性能指标的基础上,比较研究了全池泼洒复合芽孢杆菌、EM菌、类球红细菌、超浓缩光合细菌微生态制剂对养殖水质的改善情况及提高杂交青虾"太湖1号"生长性能的效果。结果表明,4种微生态制剂均可改善水质;其中,芽孢杆菌与EM菌具有较强的降亚硝态氮功能,类球红细菌和EM菌具有较强的降氨态氮作用。4种试验菌剂的调水效果排序为:类球红细菌>EM菌>复合芽孢杆菌>超浓缩光合细菌。4种菌剂不同程度提高了青虾的生长性能;其中,类球红细菌效果最为显著,其次为EM菌、复合芽孢杆菌,而光合细菌的效果不显著。 |
| 英文摘要: |
| The improving effects of four micro-ecological preparations，including compound Bacillus，effective microorganisms(EM)，Rhodobacter sphaeroides and super-concentrated photosynthetic bacteria，on water quality in freshwater shrimp culture ponds and grow-out performance of hybrid oriental river prawn “Taihu No.1”were comparatively evaluated. The water quality parameters including pH value，dissolved oxygen，ammonia-nitrogen(NH+4一N)，and nitrite-nitrogen(NO-2一N)，and prawn growth performance parameters such as fatness，average size，and feed coefficient were measured. The results indicated that all the four micro-ecological preparations could improve water quality in freshwater shrimp culture ponds，among them compound Bacillus and EM exhibited stronger effects in reducing nitrite-nitrogen，while R. sphaeroides and EM showed stronger effects in reducing ammonia-nitrogen. These four micro-ecological preparations could be ordered as R.sphaeroides>EM>compound Bacillus>super-concentrated photosynthetic bacteria in terms of their effectiveness in improving water quality. The results also showed that applications of these micro-ecological preparations could improve growth performance of hybrid oriental river prawn in varying degrees，among them R. sphaeroides gave the most remarkable effects，followed by EM and compound Bacillus，while super-concentrated photosynthetic bacteria did not provide sufficient effects. |
