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。
Effects of different cultivation methods on rape were studied for explore the simple cultivation techniques in moun- tainous area of Guizhou. The results showed that yield of no tiilage with hill seeding and ti!!age with broadcast sowing were low- er than tillage with transplanting, they were lower 11. 1%, 19. 8%, respectively, net benefits were higher than tillage with transplanting 69. 4 yuan/667m2 , 16. 9 yuan/667m2, respectively. It＇s indicated that rape direct seeded has advantage character- istics of labour saving, low input, it＇s appropriate to extend in Dazhen and similar areas.
