不同施氮量对油桃产量和品质的影响研究

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

为了探讨不同施氮量对油桃产量和品质的影响,以秦皇岛的某油桃种植示范基地为试验基地,共设置5个氮肥处理组,氮肥的施用量分别为0、216、291、366、441 kg/hm^(2),分基肥、萌芽肥和壮果肥3次施入,待油桃成熟后统计其产量并测定其品质;结果发现,氮肥施肥量为366 kg/hm^(2)的油桃单果质量、产量、可溶性糖含量、维生素C的含量、总酸含量、糖酸比均显著高于其他处理组,说明油桃采用366 kg/hm^(2)的施氮量可以获得更高的产量,并且可以提高油桃果实品质。

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/hm^(2)nitrogen application,and the sweetness and Vitamin C content of Prunus persica fruit could be improved.
