Abstract: Carbamide and KH2PO4 were set for topdressing fertilization to study the fertilization effects on leaf growth, bulb biomass and the net photosynthetic rate (Pn) of Lycoris aurea. The lightresponse to photosynthesis and a diurnal change of Pn were also studied. Results showed that the fertilization couldnt increase the leaf growth, bulb biomass and Pn significantly. L. aurea showed lighttolerance with two types of the lightresponse curve, singlepeak and parabola, and the diurnal change of Pn had a single peak. Finally a suggestion was given for the cultivation of L. aurea.
