| 摘 要： | 通过免耕直播不同播期试验,研究了播期对双季稻区油菜熟期、产量及抗性的影响。结果表明:在江西宜春,晚稻收获后抢时播种的油菜熟期较早,产量最高,抗冻性最强。播期对油菜的产量及抗冻、抗病性影响较大,对抗倒性、成熟期影响较小。在该试验中,双季稻区油菜的最佳播期为10月20日左右,推迟播种则减产显著。

| Abstract: | The effects of sowing date on the yield,maturing and resistance of rapeseed in double cropping rice region were studied through no-tillage direct seeding tests in Yichun city.The results indicated that when rapeseed was sown in time after the harvest of late rice,its mature date was the earliest,its yield was the highest,and its resistance to freeze injury was the strongest.Sowing date had great influence on the yield,freeze resistance and disease resistance of rapeseed,while it had little influence on the ... |
