摘　　要：通过“3414”肥料试验，研究了油菜的施肥效应。结果表明，江汉平原中等肥力地块上。N对油菜产量的贡献最大；配合施肥时，N、P、K的协同效率最高；提出了N、P、K推荐施用量，分别为225～270、75～105和45-75kg／hm^2。The effects of fertilization in rapeseed through ＂3414＂ fertilizer experiment were studied. The results showed that N was maximum on the yield contribution for medium-fertility land in Jianghan plain. The coordination rate of N, P, K was the best when combined with fertilizers. The fertilizer application was recommended that N,P,K were 225-270 kg/hm^2, 75- 105 kg/hm^2 and 45-75 kg/hm^2, respectively.
