本文论述了不同用量氮、钾肥对油菜产量和品质的影响。盆栽试验结果表明：增施氮肥可以明显提高油菜产量和叶片中Ｖｃ含量，降低可溶性糖含量，但增加了硝酸盐含量。施用钾肥也可明显提高油菜产量和Ｖｃ含量，而对油菜体内硝酸盐含量的影响则无规律性。
This article discusses the effects of nitrogen and potassium fertilizers on the yield and quality of rapeseed. The results of pot experiment showed that nitrogen addition could significantly increase the yield of rapeseed and the content of Vc in leaf, decrease the content of soluble sugar, but increase the content of nitrate. Potassium application also significantly increased rapeseed yield and Vc content, but had no regular effect on nitrate content in rapeseed.
