The influences of Hoagland's nutrient solution,basic nutrient solution and improved Sitainai formula and their concentrations on P.tetraphylla root morphology and physiological index were studied to provide a theoretical reference for production and application of hydroponic P.tetraphylla.The results showed that the optimum nutrient solution for P.tetraphylla was the formula of Ca(NO3)2·4H2O 236.3 mg/L,KNO3 151.8 mg/L,NH4H2PO4 28.8 mg/L and MgSO4·7H2O 123.3 mg/L.
