氮肥运筹对‘沪油杂1号'生长影响初探

Preliminary study on growth of rape cultivar 'Huyouza 1' as influenced by nitrogen fertilizer application

在不同氮肥施用量、氮肥施用比例下对杂交双低油菜品种‘沪油杂1号'进行了小区试验。结果表明:‘沪油杂1号'氮肥适宜施用量270~300 kg/hm^2;在氮肥施用量270 kg/hm^2时,年前、年后氮肥施用比例应为6.5~7.0:3.5~3.0。

A plot experiment with double low rape cultivar ＇ Huyouza 1＇ was carried out at various nitrogen fertilizer rates and ratios. The results showed that the suitable nitrogen fertilizer rate was 270-300 kg/hm^2, and when the application rate of nitrogen fertilizer was 270 kg/hm^2 the suitable nitrogen fertilizer ratio before and after the year was 6.5 - 7.0： 3.5 - 3.0.
