摘要
[目的]探讨杂交油菜德油6号的轻简高效栽培方式。[方法]在水稻收获后进行了免耕直播、免耕移栽和翻耕移栽3种不同栽培方式的试验研究。[结果]免耕直播油菜开花后的单株根系、主茎、叶片、花序以及单株总干重均显著低于免耕移栽处理和翻耕移栽处理,但后两者之间无显著差异。免耕直播油菜开花后主茎干重所占单株重的比例均高于或显著高于免耕移栽处理和翻耕移栽处理。免耕直播处理的油菜单株角果数显著低于免耕移栽处理和翻耕移栽处理,而每角果粒数、千粒重以及经济产量在3种不同栽培方式处理间均差异不显著。[结论]油菜免耕直播栽培方式是一项重要的简化省工、节本增效的技术。
[Objective] The research aimed to study a labor-saving and high efficient cultivation mode of hybrid oil rape Deyou 6. [Method]The field experiment of different cultivation mode treatments （no-tillage direct seeding, no-tillage transplanting and plowed transplanting） were carried out in hybrid oil rape Deyou 6. [Result] The average dry weight of roots, main stem, leaf, inflorescence and the whole plant weight of no-tillage direct seeding treatment significantly lower than no-tillage transplanting treatment and plowed transplanting treatment. And the proportion of main stem dry weight to whole plant of no-tillage direct seeding treatment was higher or significantly higher than no-tillage transplanting treatment and plowed transplanting treatment after flowering. The pod numbers per plant of no-tillage direct seeding treatment was significantly lower than no-tillage transplanting treatment and plowed transplanting treatment. But there was no significant difference in seeds per pod, thousand-grain weight and economic yield under different cultivation mode treatments. [Conclusion] No-tillage direct seeding mode was characteristics of simple, labor-saving, cost-saving and high efficiency technique.
