[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,菜薹产量越大,但油菜籽减产越明显。[结论]直播油菜适当应用“油薹两用”技术才能增加生产效益。
[Objective] The research aimed to promote the efficient rapeseed production technology and study the influence of “oil sow and dual use” on the direct seeding rapeseed production. [Method] The 20 cm bolting, 10 cm bolting and 3 bolting - no - bolting treatments were selected and randomly arranged in groups. The growth period was recorded and the agronomic traits, yield and benefits were investigated. [Result] The bolting increased the growth period of rapeseed, reduced plant height, reduced the effective branching position, reduced the primary branching number, increased the secondary branching number, decreased the total branching number, reduced the number of pods per plant and reduced the 1000-grain weight , Rapeseed production decreased; pick the longer the bolting length, the greater the yield of vegetable sprouts, but the more obvious the rapeseed yield reduction. [Conclusion] The proper application of live rapeseed “oil sedge dual-use” technology can increase production efficiency.
