摘要
渭北旱原甘蓝型油菜北移具有显著效益，北移的限制因素已不再是甘蓝型油菜品种，而是能否全面地贯彻配套栽培技术。配套栽培技术的核心是沟播和冬苫，而喷施多效唑是渭北旱原海拔千米以上地区甘蓝型油菜北移的一项辅助措施。
The northward movement of rapeseed(B.mapus.)has had
the noticable e-conomic returns on Weibei Highland.The variety of rapeseed(B. napu)is no
longer theconstraint to rapeseed cultivar northward movement ,but whether the package of
rape- seed cultivation can be implemented in an allround way. The core of the technical
pack-age of rapeseed cultivation if the furrow sowing and winter mulching rapeseed plants.
Also,spraying MET is only a supplementary measure for the normal movement of rape- seed(B.
napus)on Weibei Rainfed Highland with and elevation of over l 000m above sealevel.
