摘　　要：高产、高效是油菜生产目标。油菜机械收获技术可减少用工、降低劳动强度、提高油菜生产效益,但在油菜机械收获技术推广中常碰到因倒伏导致减产及机械收获操作困难等问题。甘蓝型油菜植株高大、成熟期角果易开裂,高产要求下,更易发生倒伏而不利于进行机械作业,同时也会造成收获损失率偏高,最终导致产量降低。多效唑是一种植物生长调节剂,合理施用可显著提高油菜抗倒性、改善角果发育及产量形成,进而提高油菜生产效益。从当前油菜生产实际出发,综述了施用多效唑对油菜产量、抗倒性及抗裂角性等机械收获关键性状的影响及其机理,以期为油菜机械化生产技术推广过程中多效唑的正确合理使用以及相关研究提供参考。Abstract Mechanical harvesting technology of rapeseed can reduce labor and labor intensity, but we often encoun- ter lodging when spread mechanical harvesting technology of rapeseed, which led to difficulty in mechanical harves- ting operations and loss in yield. Brassica napus L. produces tall plants that easily lodge with high yields. Pa- clobutrazol （MET） is a widely accepted regulator of plant height by inhibiting sterol and gibberellin biosynthesis. Reasonable application of MET can significantly increase crop yield and lodging resistance. Based on the current production of rapeseed in China, this article reviewed progress on mechanisms of MET that affect rapeseed yield, lodging resistance and pod shatter resistance that related to mechanical harvesting. These improvements could help augment the mechanical production of rapeseed in China
