摘　　要：近年来,油菜的收获机械化越来越受到农户重视。在油菜生产过程中,收获损失是影响油菜产量的主要因素,也是影响油菜生产成本的重要原因。本文设计油菜联合收获和分段收获对比试验,研究了不同收获方式、不同收获机型、不同配比的生长调节剂在油菜收获过程中对收获产量的影响。试验结果表明,分段收获有一定局限性,不适合在江西省大规模使用;最佳的油菜收获方式为使用生长调节剂(调节剂与水体积比为1∶10)对油菜成熟时间进行调节;采用油菜专用联合收获机械进行收获作业,不仅能有效控制收获期,主动掌握收获时间,也可以提高收获产量。In recent years,the mechanization of rape harvest has been paid more and more attention by farmers.In rapeseed production process,the main factor of rapeseed yield reduction is the loss of harvest,which is an important factor affecting the production cost of rapeseed.It is necessary to carry out the comparative experiment analysis of rapeseed mechanized harvest.In this paper,the combined harvesting experiment and sectional harvesting experiment were designed to study the effects of different harvesting methods,different harvesting types and differnet ratios of growth regulators on harvest yield during rapeseed harvesting.The results showed that the best way to harvest rapeseed at present was to use special combined harvesting machine for rapeseed harvesting,and to use the ratio of growth regulator to water of 100:1000ml/mu to regulate the ripening time of rapeseed,which could effectively control the harvesting period,grasp the harvesting time actively and increase the harvesting yield.
