摘　　要：[目的]筛选出适合黄山地区的"油蔬两用"油菜品种和最佳农艺措施组合。[方法]选用3个甘蓝型双低油菜品种皖油28、同油杂2号、中双11,研究播期和密度对油菜生育期、菜薹和菜籽产量及综合经济效益的影响。[结果]推迟播期或增加密度都能缩短油菜的生育期。适当早播或增加密度均有利于提高菜薹和菜籽产量。皖油28的9月26日播期、密度225 000株/hm2的处理组合产值最高,综合经济效益最好。[结论]该研究可为优质油菜"油蔬两用"的推广和应用提供科学依据。[Objective] The research aimed to screen out suitable rape varieties in the regions of Mount Huangshan and their optimum agronomic measures. [Method] Choosing three double-low rape varieties Wanyou 28,Tongyouza 2 and Zhongshuang 11,the effects of different planting density and sowing date on the growth period,the yield of flowering stalk and rapeseed,comprehensive economic benefits were studied. [Result]The growth period of rape could be shortened by postponing the sowing date or increasing the planting density. Both sowing early and increasing the planting density were beneficial to improve the yield of flowering stalk and rapeseed. Wanyou 28 with the sowing date of September 26 and the planting density of 225 000 plants / hm^2 obtained the highest output value and the best comprehensive economic benefits.[Conclusion]The research could provide scientific basis for the extension and application of fine rape variety＂Youshuliangyong＂.
