摘要/Abstract

摘要： 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.

Abstract: The investigation on the growth,yield and benefit of rape inter-and mixed cropped with milk vetch showed that comparing with sowing rape under zero tillage,the physiological and ecological characters of transplanted rape, including its height,leaf size,root diameter,opening degree and yield were obviously improved.Under zero tillage,mixed cropping had an obvious advantage than inter-and single cropping.After tillage,the yield of transplanted rape under mixed cropping was 11.9% more than that under single cropping with zero tillage.The benefit of transplanting rape under mixed cropping with tillage was the biggest,followed by single cropping rape with zero tillage.It could be concluded that the patterns of transplanting rape under mixed cropping after tillage and zero tillage had the best physiological and ecological effects,not only increasing rape yield and income,but also improving soil fertility.
