| 摘 要： | 实验以枯草芽孢杆菌和光合细菌为研究对象,研究了生物絮团对中华锯齿米虾养殖水体酸碱度、氨氮、亚硝酸氮、COD等水质指标的调节及其在促进米虾生长方面的作用。结果显示,添加了生物絮团的实验组,比对照组养殖水体的亚硝酸氮含量降低54%,COD水平降低39%,氨氮含量降低35%,pH值稳定保持在适宜的水平,中华锯齿米虾的存活率和增重率也有显著提高。结果表明,生物絮团的使用,能够有效调节水质,促进中华锯齿米虾的生长。

| Abstract: | In this experiment,biological floc consisted of Bacillus subtilis and Photosynthetic bacteria were added into culture water of Neocaridina denticulate sinensis.We determind the concentration of COD,NH4＋-N,NO2——N and pH value,and studed the effect of biological floc on promoting the growth of N.denticulate sinensis.The results showed that,in the culture water added biological floc,the content of COD,NH4＋-N and NO2——N were reduced 39%,35% and 54%,respectively,the pH value stabilized at appropriate level,and the survival and weight gain of N denticulate sinensis also increased significantly.The use of biological floc,can really regulate the culture water quality effectively,and promote the growth of cultured organisms. |
