摘 要:在宁夏永宁县小任果业设施果树种植基地,通过田间试验研究了不同施氮量水平对设施油桃产量和品质的影响。结果表明:在一定范围内,随着施氮量的增加,油桃产量显著增加;当施氮量超过375 kg/hm2时,随着施氮量的增加,油桃产量下降。随着施氮量的增加,糖分累积显著下降,Vc含量先下降后升高,糖酸比下降。A field experiment was conducted to study the effects of different N application rate on the yield and quality of Nectarine in greenhouse at the Xiaoren Fruit Industry Company fruit tree planting base in Yongning county in Ningxia. The results showed that in a certain range the nectarine yield increased significantly along with the increased rates of nitrogen application. However, when the N application amount exceeded 375 kg/hm2, along with the increased rates of nitrogen application the yield of the nectarine decreased. The sugar accumulation rate as well as the sugar and acid ratio decreased along with the increased N application amount. The content of Vitamin C in nectarine decreased along with increased N application, but further increased N application amount led to. the rising up of the Vitamin C.
