氮磷钾化肥与有机肥不同配比对油菜生长及产量、品质的影响

The effect of different ratios of nitrogen,phosphorus,potassium and organic fertilizer on growth,yield and quality of rape

运用田间小区试验探讨了氮磷钾化肥与有机肥不同配比对油菜生长及产量、品质的影响,以期为油菜大田生产科学、适量施肥提供依据。研究结果表明,在本试验条件下,施N 180 kg/hm2、P2O5108 kg/hm2、K2O144 kg/hm2、谷壳粉1 800 kg/hm2时,油菜的经济性状和产量表现最佳。

In order to privde the experimental basis for optimum fertilizer on field production, the effect of different ratios of N, P, K and organic fertilizer on rape＇s growth, yield and quality were discussed. The results showed that the best NPK and organic fertilizer application for rape was N 180 kg/hm2, P2 05 108 kg/hm2, K20 144 kg/hm2, rice husk powder 1 800 kg/hm2 , getting the best effect on economic characters and yield.
