In order to investigate the effects of different nitrogen application rates on Prunus persica yield and quality,a Prunus per-sica planting demonstration base in Qinhuangdao was set up as the experimental base.A total of 5 nitrogen fertilizer treatment groups were set up,and 40 Prunus persica trees with the same growth were selected from each treatment group and divided into 5 parallel groups with 8 trees in each parallel group.Each parallel group applied fertilizer according to the amount of nitrogen fertilizer mentioned above,divided into base fertilizer,germination fertilizer and strong fruit fertilizer for 3 times,and counted the yield and measured the quality of Prunus persica after maturity.The results showed that the yield of Prunus persica fruit could be higher with 366 kg/hm2 nitrogen application,and the sweetness and Vitamin C content of Prunus persica fruit could be improved.
