Effects of Different Nitrogen Application Rates on the Yield and Quality of Prunus persica
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.
