油菜(Brassica napus L.);棉田套播;产量差异;播期;密度
摘  要：
以常规油菜(Brassica napus L.)华双5号为材料,调查分析了棉田套播油菜的产量表现和产量差异原因,研究了播期和密度对棉田套播油菜产量及构成因素的影响。结果表明,①棉田套播油菜产量主要分布在3 000～3 750 kg/hm2,种植密度和有效角果数是影响产量的关键因素。②播期和密度对产量构成因素有明显影响,播期推迟,密度增加,单株有效角果数、每角粒数均表现明显减少;播期和密度对千粒重影响较小。③播期、密度及其互作对产量影响显著,播期推迟,油菜产量降低,不同播期要求最适播种密度不同。

rapeseed(Brassica napus L.);under-sowed in cotton field;yield difference;sowing date;sowing density
摘  要：
Using normal rapeseed Huashuang No.5 as material,the yield performance of rapeseed under-sowed in cotton field and the reason for the yield differences were investigated focusing on the impact of sowing date and density on rapeseed yield as well as its contributing factors.The result showed that the yield of rapeseed under-sowed in cotton field range d from 3 000 to 3 750 kg/hm2.Sowing density and number of effective pods were the key factors influencing the yield.Sowing date and sowing density had evident influences on the yield contributing factors,as effective pods number per plant and seeds number per pod decreased obviously with the delay of sowing date or increasing of density.However,the effect of sowing date and sowing density on kernel weight was small.The effect of sowing date,sowing density and their interaction on the yield was significant.The yield would decrease when sowing date was delayed.The appropriate density differed with the difference of sowing date.
