采用7种耕种方式研究油菜与紫云英间混作系统中油菜生长发育、产量形成及其效益.结果表明,育苗移栽油菜的株高、叶片大小、根颈粗、开盘度以及产量指标均明显优于免耕直播油菜;与紫云英混作的免耕直播油菜,各形态指标均优于免耕直播间作和单作油菜.耕翻后与紫云英混作的育苗移栽油菜产量比免耕直播单作油菜增产11.9%;与紫云英混作的免耕育苗移栽油菜产量与免耕直播单作相近.耕翻后与紫云英混作的育苗移栽油菜产值和效益最大,免耕直播油菜单作其次.结合产投比和土地当量比,耕翻后与紫云英混作育苗移栽油菜和与紫云英混作免耕育苗移栽油菜两种方式综合效益最高,增产增收,增加有机肥源,提高土壤肥力.
Seven kinds of tillage methods were used to study the growth, yield and benefits of rapeseed (Brassica napus L.) in rapeseed intercropping system.The results showed that the plant height, leaf size, root-neck coarseness, opening degree and yield of rapeseed transplanting rapeseed Is better than no-tillage direct seeding rape.The no-tillage direct seeding rape mixed with astragalus mongolica had better morphological indexes than no-tillage direct seeding intercropping and single-crop rape.The yield of rapeseed transplanting rapeseed The yield of transplanting rapeseed mixed with Chinese milk vetch was the same as that of no-tillage direct-seeding single-cropping.The yield and benefit of transplanted rapeseed were the highest with no-tillage transplanting Oilseed rape as the second.Combined with the production to investment ratio and land equivalent ratio, tillage after the turnip mixed with transplanting rapeseed and rapeseed mixed with no-till nursery transplanting rape two ways to maximize the overall efficiency, increase production and increase organic Fertilizer, improve soil fertility.
