不同氮肥施用量对茉莉王葡萄果实品质的影响

Effects of Different Nitrogen Application Rates on Quality of King Jasmine Grape

[目的]研究不同氮肥施肥量处理对茉莉王葡萄的果实品质和产量的影响。[方法]在葡萄园区,氮肥设施入量为0、300、450、600 kg/hm^(2)4个处理试验区(CK、N1、N2、N3),观察对葡萄果实品质的影响。[结果]施肥量为450 kg/hm^(2)时,葡萄的果实品质质量和葡萄果实产量达到最高值。[结论]可为氮肥在茉莉王葡萄上的使用提供理论依据。

[Objective]The effects of different nitrogen fertilizer rates on fruit quality(soluble solids,organic acids,vitamin C)and yield of King Jasmine grape were studied.[Method]In the vineyard area,under the different rate of nitrogen fertilizer 0,300,450 and 600 kg per hectare(CK,N 1,N 2,N 3),the effect of grape quality was studied.[Result]The quality and yield reached the highest value when the fertilization amount was 450 kg/hm^(2).[Conclusion]It could provide theoretical basis for the application of nitrogen fertilizer on the grape of king jasmine.
