According to the problem of lacking suitable planter for permanent raised bed (PRB) in one crop a year oasis agricultural region of northwest China, a 2BFML-5 no-till planter for PRB was designed, the parameters of key components for opener, reshaping plough etc. were analyzed and decided. By means of adopting sharp-angle opener, the new planter could cut stubble and break clod, what was more, 5 cm of vertical depth difference between seeder and fertilizer could be achieved easily. The reshaping plough could not only cover seeder row effectively, but also reshape the old bed perfectly. The planter could finish stubble cutting, ditching and fertilizing, seeding, covering, compacting and reshaping bed in one pass. Experimental results showed that under straw cover of 3682kg/hm2, the planter, which was effective in entering the soil, anti-blocking and increasing emergence rate by 6.25% and yield by 2.7% respectively, could meet the developing requirement of PRB in northwest China.
