Abstract：In order to determine the effects of different nitrogen fertilizer rates on broccoli NUE,nitrogen contents and yields,the experiment was conducted at 5 different application levels 0 kg per 667 m2,5 kg per 667 m2,10 kg per 667 m2,20 kg per 667 m2 and 30 kg per 667 m2. We used correlation analysis and regression equations to understand the impact of nitro-gen on the broccoli. The results showed that the correlation between amounts of nitrogen fertilizer with NUE was significant-ly negative. There was a significant positive correlation with the amount of nitrogen fertilizer and plant nitrogen content. The nitrogen effect equation of broccoli is:Y=0.829 5X2+33.171X+543.55,It can achieve the maximum benefit when the ni-trogen fertilizer amount was 19.46 kg per 667 m2 under the same conditions.
