Abstract:: Taking the cut-flower of OT type Lily ‘Manissa’ as test material，under different level of fertilization，the effects of quality at different nutrient combinations A，B that were from imported fertilizer Hua Duoduo and C from AR(analytical regent) chemicals on the plant of chlorophyll content，photosynthetic characteristics and amount of dry matter in the experiment were studied，so as to fertilize the Lily more scientifically and accurately.The results showed that the photosynthetic ability and the amount of dry matter accumulation of 7.5 g/plant and 12.5 g/plant treatments were obviously superior to the control group CK and 2.5 g/plant treatment groups.Under 7.5 g/plant treatments，the dry matter accumulation of group A was higher than the other two groups and got the maximum benefit with low input as well.Under 12.5 g/plant treatments，the group C and B were better than the group A in the photosynthetic ability and accumulated quantity of dry matter，and group C had the best effect on the improvement of lily cut flower followed by group B.
