摘　　要：采用3因素2项分组试验设计,研究了贵杂4号油菜成熟期经济性状及产量表现。结果表明,处理2(垄作+宽窄行+喷多效唑)的千粒重和产量最高,分别为4.967 g和174.53 kg.667 m-2,为最佳栽培组合措施。其中"垄作+宽窄行"互作效应能提高油菜单株有效角果数和千粒重;喷多效唑对油菜产量的影响达极显著,而垄作、宽窄行的影响不显著。By grouping test design to plant Guiza 4 rape, the economic characteristics of maturity and the yield of the rape were studied. The results showed that the treatment 2 （ ridge ＋ wide - narrow row ＋ spraying PP333 ） is the best combination measure for cultivation. The 1 000 - grain weight and the yield of treatment 2 reached their highest values with the corresponding numbers of 4.967 g and 174.53 kg-667 m-2. The treatment of ridge ＋ wide - narrow row could effectively raise the number of pod per plant and the 1 000 - grain weight. Spraying PP333 had a very significant effect on the yield of rape, while ridge and wide - narrow row did not have.
