【摘要】 在罗非鱼鱼苗培育池塘和鱼种饵料中应用纳米生物助长器。试验结果表明:池塘放置试验组与对照组相比总产量、成活率、饵料蛋白质效率分别提高15.53%、24.15%、8.95%,饵料系数降低8.25%;饵料放置试验组与对照组相比增重率、饵料蛋白质效率分别提高11.74%、20.67%,饵料系数降低17.12%。并对纳米生物助长器的增产作用进行了分析,提出了在淡水池塘应用纳米生物助长器清洗和晾晒周期的建议。更多还原

【Abstract】 The nanometer growth promoter model were used in the Tilapia nilotica fry cultivate pond and finglering feed.The experimental results show that nanometer growth promoter model used in the pond trail make the total yield,surrival rate,feed protein efficiency raise 15.53%,24.15%,8.95% seperately,the feed coefficient dropped 8.25% by the contrast group.And compared with the contrast group nanometer growth promoter model used in feed make dynamiting rate and feed protein efficiency raise 11.47% and 20.67%,the feed coefficient dropped 17.12%.At the same time we analysed the promotion effect of yield which the nanometer growth promoter model played,put forward a proposal about cleaning and drying the nanometer growth promoter model in freshwater fish-farming.更多还原
