【摘要】 中油肥1号是中国农业科学院油料作物研究所选育的肥油兼用型绿肥油菜新品种,湖北省两年三点试验结果表明,在肥料投入低的情况下,相比对照阳光2009,地上部生物量压青鲜重平均为43 560.0kg/hm²,鲜重增加15.81%;植株养分还田量平均分别为氮（N）88.20 kg/hm²、磷（P₂O₅）14.25 kg/hm²、钾（K₂O）119.10 kg/hm²;植株氮、磷、钾养分还田量分别增加21.2%、12.5%和17.3%。该品种在低氮肥投入条件下菜子产量略高于主栽对照品种,其菜子品质符合国家双低油菜子标准,在正常栽培条件下可以作为兼收菜子型油菜品种进行菜子生产。更多还原

【Abstract】 Zhongyoufei 1 was a new rapeseed variety which could use for green manure or oilseed production which was bred by the oil crop research institute of Chinese academy of agricultural sciences. The results of 2-year multi-site experiment in Hubei province showed that,under low fertilizer input conditions,the fresh weight of shoot biomass was 43 560.0 kg/hm² on average,which was 15.81% increase than that of the control variety Yangguang 2009,the amount of N,P（P₂O₅）and K（K₂O）returning were 88.20 kg/hm²,14.25 kg/hm² and 119.10 kg/hm²,increasing by 21.2%,12.5% and 17.3%. The seed yield of Zhongyoufei 1 was slightly more than that of the control cultivar under low N fertilizer input conditions,and its seed quality meeted the criteria of double low rapeseed in China.Under normal fertilizer application,the variety could be used as seed production and green manure.更多还原
