摘　　要：通过田间小区试验和大田试验示范相结合、并采用多年多点的单因子控制研究,建立了油菜田超低密度栽培与间套种相结合的高效立体种植模式。6年连续示范与推广,油菜套种7种不同农作物三茬四作和四茬五作种植模式平均年产值达75112.50元/hm^2,而传统油-稻-稻耕作制平均年产值只有18612.00元/hm^2,以油菜为主栽作物的高效立体种植法比传统栽培法增加产值56500.50元/hm^2,是传统栽培法的4.04倍。超低密度油菜田高效立体种植模式有利于调动城市郊区农民种植油菜的积极性,提高种田的经济效益。Undertaking 6 year's plot test and field demonstration through one factor controlling research at several places, a brand new cultivation model named superthin planting of winterrape combining planting in the row and interplanting of vegetables has been build up. Our experiments show that winter rape' s superthin planting with interplanting of vegetables, including winter rape following quick succession interplanting potato, radish, garlic sprouts, coriander, spinach, have gained great economic effect.The main production value for the new stereo planting model is as high as 75,112.50 yuan per ha, while on the other hand the traditional winter rape followed rice rice tricropping is only 18,642.00 yuan per ha.This new stereo planting of winter rape represents a high economic effect planting system for the suburbs.
