[目的]推广高效油菜生产技术，研究“油薹两用”对直播油菜生产的影响。[方法]设摘薹20cm、摘薹10cm和不摘薹3个处理，3次重复，随机区组排列，记录生育期，考察农艺性状、产量和效益。[结果]摘薹使油菜生育期延长，株高降低，有效分枝位降低，一次分枝数减少，二次分枝数增加，总分枝数减少，单株角果数减少，千粒重减小，油菜籽产量减少；摘薹长度越长，莱薹产量越大，但油菜籽减产越明显。[结论]直播油菜适当应用“油差两用”技术才能增加生产效益。

[Objective] The effects of direct-seeding rape for both oilseed and vegetable uhhzatlon were studied in order to popularize high efficient production technology of rape. [Method] Three treatments （flower stalk cut off in 20, 10, 0 cm） with three repeats in randomized arrangement were done, and the growth periods were recorded, agronomic characters,yield and benefit were examined. [Result] Cutting off the flower stalk of direct-seeding rape result in extended growth period, lower plant height, reduced effective branch height , less number of first effective branch, more number of secondary effective branch, less total number of effective branch, less silique number of per plant, less 1 000 grains weight, and decreased yield of oilseed. Meanwhile, when the length of cutted-off flower stalks increased, the output of flower stalk for vegetable increased, and the effect on reduction of oilseed yield was more obvious. [Conclusion] The total production benefit could increase when applied production technology about both oilseed and vegetable utilization on direct-seeding rape appropriately.
