我国南方冬油菜机械化生产农艺研究进展

Research of agronomic techniques for mechanical production of winter rape (Brassica napus L.) in south China

油菜机械化生产是我国油菜生产发展的方向,近年来在南方冬油菜区进行了适合机械化生产的油菜品种筛选和鉴定,农机和农艺配套技术试验示范。本文综述了在油菜机械直播和机械移栽、抗倒伏措施及理想株型构建、施肥技术、病虫草害化学防治、化学催熟技术、机械收获技术等方面的研究概况,并探讨了存在的问题及今后的研究方向。

Mechanization is the future direction of winter rape.Breeding and identification of varieties for mechanical production as well as trial demonstration of agricultural machinery and agronomy were conducted in south China in recent years.The agronomic techniques,including mechanical sowing and transplanting,lodging resistance and optimizing plant type,fertilizer application,chemical prevention of insect disease and weed,chemical ripening,and mechanical harvesting were analyzed.The associated problems and perspectives of mechanical production of winter rape were also discussed.
