Abstract: Dry conditions in the field by field experiment to study the application of phosphate (P2O5) 150 kg/hm2, potash (K2O) 225 kg/hm2, based on different nitrogen levels (0,75,150,225 kg/hm2;N0,N75,N150,N225) of lily yield, nutrient uptake and quality. The results showed that one, two, three years production of raw annual growth rate of lily, respectively (51.69±25.76)%, (110.71±40.85)%, (88.29±21.45)%, the largest increase for the second year, followed by the third year. Lily total sugar, starch and soluble sugar content increased with nitrogen rate generally decreased, following increasing content of crude fiber and crude protein increased as nitrogen rate was high after the first drop and then increase the trend, which lily under nitrogen content of crude protein were higher than N0, and soluble sugar content were lower than N0. When nitrogen is 75 kg/hm2, the total sugar and starch content increased significantly compared with N0 (an increase of 3.3% and 5.1%, P<0.05). When the nitrogen application rate of 225 kg/hm2, the soluble sugar content was significantly decreased compared with N0 (down 6.2%, P<0.05). When nitrogen is 75 kg/hm2, the crude protein content increased significantly compared with N0 (an increase of 20.3%, P<0.01), and when the nitrogen application rate of 225 kg/hm2, the ratio of N0 was increased significantly (an increase of 37.9%, P<0.05). Nitrogen is the impact of yield and quality of lily one of the main factors.
