不同用量氮、钾肥对油菜产量及品质的影响

Effects of Different Application Rates of Nitrogen and Potassium Fertilizers on Yield and Quality of Rape

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。

The results of pot experiments showed that in higher N application treatments the rape yield and Vc content in leaves incresed significantly, but the soluble sugar was decreased, and the nitrate content was more accumulated. The rape yield and Vc content also increased when the K fertilizer was applied, but the effect on nitrate inrape plant was not regularity.
