以浙江省油菜主栽品种＂浙油50＂为对象进行不同施氮量试验,研究不同施氮量对油菜菌核病发生程度及产量的影响。研究结果表明：浙油50每667 m2适宜施N量为15～20 kg,在该施氮水平下,油菜菌核病发生较轻,且产量水平高。

In this paper,an experiment of different nitrogen-applied levels to the main cultivars "Zheyou50" in Zhejiang was carried out,and the effects of different nitrogen levels on occurance degree of sclerotium and crop yield were explored.The results showed that,15-20 kg N/667 m2(225-300 kg N/hm2) is suitable for Zheyou50.In this N-applied level,the harmness of sclerotia sclerotium was lighter and the yield was high.
