摘要
以江淮地区推广的皖油18、中油杂10号、中双8号3个优质油菜品种为材料,设计播期和密度试验,研究了品种、播期、密度及其交互效应对优质油菜菜薹、菜籽产量与经济效益的影响。结果表明:(1)播期对菜薹产量影响不显著,品种×密度、播期×密度、品种×播期×密度互作效应不显著,品种、密度对菜薹产量有极显著影响。(2)密度对菜籽产量影响不显著,品种×播期、品种×密度、品种×播期×密度互作效应不显著,品种、播期对菜籽产量有极显著影响。(3)综合评价以中油杂10号、8月28日播种、密度1.2×105株/hm2时产值最高,经济效益最好。
Using three high quality rape varieties, i.e. Wanyou18, Zhongyouza10 and Zhongshuang8, as materials, choosing variety, sowing date and density as experimental factors, the main and interaction effects on the yields of rape stalk and rapeseed, and economic benefit were studied. The results showed that： （1） Sowing date had no significant effect on stalk yield. The interacting effects of variety and density, sowing date and density, variety and sowing date and density were not significant. But variety and density had significant effect on the yield of rape stalk. （2） Density had no significant effect on rapeseed yield. The interacting effects of variety and sowing date, variety and density, variety and sowing date and density were not significant. But variety and sowing date had significant effect on rapeseed yield. （3） Comprehensive evaluation indicates that Zhongyouza10, sowing date was August 28, density was 120000 plants/hm^2 had the highest output value and the best economic benefits.
