The utility model relates to the technical field of wormwood topdressing, and discloses a topdressing device for wormwood cultivation, which comprises a fixing frame, a material containing box for containing
fertilizer is fixed in the middle of the fixing frame, a fixing rod is fixed on the surface of the fixing frame, a sliding rod is slidably connected to the surface of the fixing rod, and a discharging mechanism is arranged at the bottom of the fixing frame; the discharging mechanism comprises a sliding block II and a discharging
pipe. Through telescopic adjustment of the discharging
pipe, the distance between the discharging
pipe and the material receiving
barrel can be enlarged or shortened, the distance can be adjusted according to the row spacing of wormwood, the wormwood on the two sides can be fertilized at the same time during fertilization, the situation that only one row of wormwood is fertilized is avoided, and the working efficiency is improved; meanwhile, the influence on
fertilizer absorption due to the too
far distance from the wormwood roots during
fertilizer application is avoided, and the situation that the materials remain to the interior and cannot be completely discharged when being discharged through the discharging pipe is avoided through the inclination between the discharging pipe and the sliding sleeve.
