摘　　要：为了探明甘蓝型优质杂交油菜新品种臻油89适宜的轻简、高效、节约的种植模式及相应的栽培技术措施,采用单因素完全随机区组设计,研究育苗移栽、机播机收和免耕直播等3种不同种植方式对臻油89产量和经济效益的影响。结果表明:机播机收和免耕直播方式下臻油89的全生育期分别为207d和204d,分别比育苗移栽提前成熟5d和7d。机播机收和免耕直播方式下臻油89的株高、分枝数、有效角果数、角粒数和单位面积产量显著低于育苗移栽,但机播机收方式的单位面积纯收入最高,达449.5元/667m2;免耕直播次之,为311.5元/667m2;育苗移栽最低,仅74.5元/667m2。机播机收和免耕直播方式的经济效益明显高于育苗移栽,其中又以机播机收栽培方式的经济效益最高、最理想。The effects of three different cultivation patterns of seedling transplantation,mechanical sowing and harvest,and no-tillage direct seeding on yield and economic benefit of Zhenyou 89 were studied by the single completely randomized plot design to probe the cultivation pattern with simplicity,high efficiency and economy and the corresponding cultivation technological measures for Zhenyou 89,a new good hybrid rapeseed variety.Results：Total growth period of Zhenyou 89 under the mechanical sowing and harvest,and no-tillage seeding cultivation pattern is 207 dand 204d,5dand 7dearlier than under the seedling transplantation cultivation pattern respectively.Height,branches,effective pods,grains per pod and per unit area yield of Zhenyou 89 under the mechanical sowing and harvest,and no-tillage seeding cultivation pattern is significantly lower than under the seedling transplantation cultivation pattern separately.Per unit area pure income of Zhenyou 89 under the mechanical sowing and harvest cultivation pattern is the highest（449.5Yuan/667m2）,followed by under the no-tillage cultivation pattern（311.50Yuan/667m2）and under the seedling transplantation cultivation pattern（74.5 Yuan/667m2）,which indicates that the economic benefit of Zhenyou 89 under the mechanical sowing and harvest cultivation pattern and no-tillage cultivation pattern is significantly higher than under the seedling transplantation cultivation pattern and the mechanical sowing and harvest cultivation pattern with the maximum economic benefit should used in production of Zhenyou 89.
