肥料运筹对不同熟期品种油菜产量和品质的影响

对3种不同熟期的油菜品种采用2种肥料运筹模式进行种植,研究其对不同熟期油菜品种产量和品质的影响。结果表明：各处理间的产量、单株角果数、每角粒数、千粒重均存在显著或极显著差异;中熟品种华油杂62和华油杂9号的产量较高;早熟品种青杂7号的产量较低,其单株角果数明显比中熟品种少,但千粒重高。在品质方面,对同一品种,随着氮素水平的提高,蛋白质的含量有所增加,含油量有所降低;同一氮素水平下,不同品种的蛋白质含量无明显差别,青杂7号的含油量较华油杂9号和华油杂62高,华油杂9号与华油杂62的含油量无明显差别。不同氮素水平对同一品种的芥酸含量无明显影响,在同一氮素水平下,华油杂62的芥酸含量最高,华油杂9号...

Summary:对3种不同熟期的油菜品种采用2种肥料运筹模式进行种植,研究其对不同熟期油菜品种产量和品质的影响。结果表明：各处理间的产量、单株角果数、每角粒数、千粒重均存在显著或极显著差异;中熟品种华油杂62和华油杂9号的产量较高;早熟品种青杂7号的产量较低,其单株角果数明显比中熟品种少,但千粒重高。在品质方面,对同一品种,随着氮素水平的提高,蛋白质的含量有所增加,含油量有所降低;同一氮素水平下,不同品种的蛋白质含量无明显差别,青杂7号的含油量较华油杂9号和华油杂62高,华油杂9号与华油杂62的含油量无明显差别。不同氮素水平对同一品种的芥酸含量无明显影响,在同一氮素水平下,华油杂62的芥酸含量最高,华油杂9号次之,青杂7号最低;硫甙的变化趋势和芥酸的变化一致。

Fertilization; Different maturities; Rape; Yield; Quality
The effects of 2 fertilization patterns on the yield and quality of 3 rape varieties with different maturities were studied.The results showed that there were very significant differences in yield,number of pod,seeds per pod and 1000-grain weight among different treatments.Middle-mature variety Huayouza 62 and Huayouza No.9 had higher yield.Early-mature variety Qingza No.7 had lower yield,and its number of pod was obviously less than that of middle-mature varieties,but it had higher 1000-grain weight.As for seed quality,the protein content of the same variety increased and oil content decreased along with the increase in nitrogen application rate;under the same application rate of nitrogen,protein content
