The Gracilarla tenuistipitata Var. liui were built 5 density groups for: 10g/L, 20g/L, 25 g/L, 30g/L and 35g/L. Experiment were conducted in lab in 24 hours, on degrading NH4-N,NO2-N,NO3-N,PO4-P.

• 细基江蓠繁枝变种净化养殖废水研究本文将细基江蓠繁枝变种(Gracilarla tenuistipitata Var.；liui)分成10g/L；20g/L；25 g/L；30g/L；35g/L等5个密度组；在实验室条件下研究其24h之内对排水沟废水营养盐NH4-N；NO2-N；NO3-N；PO4-P的吸收降解效果的差异。
