文章针对秋播油菜播种时干旱等不利天气和播栽费工、费时、投入大等问题,在现行成熟油菜播栽技术基础上集成了一套稻田油菜免耕直播机械开沟技术。该技术具有茬口好、墒情足、易操作、省人工、节成本、宜机收、产量高等特点,效益明显高于移栽油菜和常规直播油菜,适宜在双季稻、一季晚稻、中稻再生稻等两熟制或三熟制地区和生产劳动力以留守老人、妇女为主的家庭推广应用。 In this paper, a set of tillage and tillage technology for rapeseed no-tillage direct injection on paddy field was integrated on the basis of the current mature rapeseed planting technology. The technology has a good crop condition, adequate moisture content, easy operation, labor-saving, cost-saving, suitable for harvest, high yield, the efficiency is significantly higher than transplanted rape and conventional live rapeseed, suitable for double cropping rice, Such as two cooked or three cooked areas and the production of labor to stay behind the elderly, women-based family promotion and application.
