摘　　要：为丰富宁夏引黄灌区麦后复种饲料油菜品种多样性,以福油128(P1)、福油158(P2)、宁杂19(P3)、金油杂158(P4)和华油杂62(P5,对照)为材料,通过田间试验,研究了5个饲料油菜品种在相同播种量处理下的株高、茎粗、SPAD值、单株干质量、植株氮磷钾养分含量和养分累积量、饲草产量。结果表明:收获时,P4的单株干质量与P5的无显著性差异;P4、P3、P2的株高、茎粗、SPAD值与P5的差异均无统计学意义;油菜生长过程中氮磷钾养分含量下降,但养分累积量呈不断增加趋势;本试验中,P1的地上部鲜草产量最低,为46 200 kg/hm^2,P5的鲜草产量最高,为57 200 kg/hm^2,P3、P4的鲜草和干草产量与P5的均无显著性差异。综合分析,P4、P3、P2可在宁夏引黄灌区推广。In order to increase the diversity of post-wheat multiple-feed rapeseed in Ningxia Yellow River Irrigation Area,Fuyou 128(P1),Fuyou 158(P2),Ningza 19(P3),Jinyouza 158(P4)and Huayouza 62(P5,control)was studied in this study.Through field trials,the plant height,stem thickness,SPAD value,dry weight per plant,plant nitrogen,phosphorus and potassium nutrient content and nutrient accumulation,forage yield of the five rapeseed varieties were treated by use of the same sowing rate.The results showed that:at harvest,there was no significant difference between P4 dry weight per plant and P5;plant height,stem thickness,SPAD value of P4,P3,P2 and P5 were not statistically significant;nitrogen,phosphorus and potassium nutrient content during rape growth were decrease,but the cumulative amount of nutrients continue to increase;under this test condition,P1 had the lowest fresh grass yield at 46200 kg/hm^2,P5 had the highest fresh grass yield at 57200 kg/hm^2,the fresh grass and hay yields of P3 and P4 were not significantly different from P5.Comprehensive analysis,P4,P3,P2 can be popularized in Ningxia Yellow River Irrigation Area.
