【摘要】 为探索山区油菜大面积生产的轻简化栽培技术,进行了不同栽培方式对比试验。结果表明:免耕点播、翻犁撒播产量分别比翻犁移栽低11.1%、19.8%,纯收益分别比翻犁移栽多69.4元/667m2、16.9元/667m2,说明油菜直播具有节约劳动力、降低生产成本的优势,今后在油菜生产上可因地制宜推广直播技术。更多还原

【Abstract】 Effects of different cultivation methods on rape were studied for explore the simple cultivation techniques in mountainous area of Guizhou.The results showed that yield of no tillage with hill seeding and tillage with broadcast sowing were lower than tillage with transplanting,they were lower 11.1%,19.8%,respectively,net benefits were higher than tillage with transplanting 69.4yuan/667m2,16.9yuan/667m2,respectively.It’s indicated that rape direct seeded has advantage characteristics of labour saving,low input,it’s appropriate to extend in Dazhen and similar areas.更多还原
