摘  要：
通过试验的方法利用罗非鱼养殖密度为50 kg/m-3时循环水养殖系统（RAS）尾水配制水培生菜营养液,同时侧面研究了RAS尾水对水培生菜生长及品质的影响。试验设置5个不同梯度的营养添加试验组,分别是富通水培营养液通用配方营养成分的1/5 （T1）, 2/5 （T2）, 3/5 （T3）, 4/5 （T4）,和全部（T5）,并以60%浓度的RAS尾水为底水,配制成5份新的水培营养液;以不掺RAS尾水的富通水培通用营养液作为对照组（CK）。试验结果表明,向RAS尾水中适当添加营养能够促进水培生菜生长,并提高水培生菜品质。与CK组相比,T4组增加了18.1%; T5组增加了19.4%。从最终产量来看,T5组最高;综合品质与产量因素,T4组最优。根据试验结果,营养成分的添加方案还能够继续优化。本研究为RAS排放的尾水提供了一种环境友好型的净化方式;同时尝试利用尾水培育水培生菜,为未来开发新型的鱼菜共生模式提供了数据基础。

摘  要：
The experimental method was used to prepare hydroponic lettuce nutrient solution by using the tailwater of the circulating aquaculture system(RAS) at a tilapia culture density of 50 kgm-3, and the effects of RAS tailwater on the growth and quality of hydroponic lettuce were also studied. The experiment set up five different nutritional addition test groups, which are 1/5(T1), 2/5(T2), 3/5(T3), 4/5( T4), and all(T5), and using 60%RAS tail water as the bottom water, 5 new hydroponic nutrient solutions were prepared; Futong hydroponic universal nutrient solution without RAS tailwater was used as a control group(CK). The test results show that proper addition of nutrients to RAS tailwater can promote the growth of hydroponic lettuce and improve the quality of hydroponic lettuce. Compared with the CK group, the T4 group increased by 18.1%; the T5 group increased by 19.4%.From the perspective of the final output, the T5 group is the highest; comprehensive quality and yield factors, the T4 group is the best. According to the test results, the nutritional supplement scheme can be optimized. This study provides an environmentally-friendly method for purifying tailwater discharged from RAS. At the same continuously time, it attempts to cultivate hydroponic lettuce by using tailwater, which provides a data basis for the development of a new aquaponics model in the future.
