In this paper, a vertical rotary tillage with fixed-layer fertilizer performance was designed, the design process was introduced. And the fertilization performance was verified by Edem software simulation. The final field test shown that the average tillage depth could reach 26.8cm; the fertilizer layer was concentrated under the soil surface 45-48mm; the width of the fertilizer layer was 238-240mm; the thickness of the fertilizer layer was 223-226mm, which satisfied the design requirements.
