【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。更多还原

【Abstract】 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.更多还原
