摘　　要：采用裂区试验设计 ,研究了肥料运筹和栽期对甘蓝型黄籽杂交油菜新品种“渝黄一号”超稀植产量及其有效性状的影响 ,寻找出产量 415 7.1kg/hm2 (B2 A2 )和 3 65 3 .6kg/hm2 ,加黄籽率 93 .2 % (A1 B2 )的肥料运筹和栽期的最佳方案。 10月 12日栽(B2 ) ,A2 的肥料运筹是N肥基∶追∶薹为 5∶3∶2、PK基施 ;A1 的肥料运筹是N肥基∶追∶腊 :薹为 5∶3∶1∶1,P肥基∶追∶腊为 5∶4∶1,K肥追∶腊∶薹为 3∶2∶5。Under the condition of super-lower density planting, the effect of fertilizer and transplanting date on yield and effective characters of rapeseed--Yuhuang No.1, new hybrid of yellow-seeded rapeseed (Brassica napus L), was analyzed with using split plot design. The results indicated that the treatment A 2B 2 had the highest yield (4 157.1kg/hm 2) and the treatment A 1B 1 was with higher yield (3 653.6 kg/hm 2 ) and yellow-seeded rate (93.2%). In this experiment,the first-rank suited transplanting date (B 2) was October 12.In A 1,nitrogenous fertilizer was consisted of three ports: 50% fertilizer before transplanting(FBT), 30% fertilizer after transplanting(FAT) and 20%fertilizer at stem extension stage(FSES); phosphate fertilizer and potash fertilizer were 100% FBT, but in A 2, nitrogenous fertilizer was consisted of 50% FBT, 30% FAT, 10% fertilizer at flower bud differentiation stage (FSES) and 10% FSES; phosphate fertilizer included 50% FBT, 40% FAT and 10% FFBDS; meanwhile, potash fertilizer included 30% FAT, 20% FFBDS and 50% FSES.
