Fertilizing device and method for farmland soil improvement

The invention discloses a fertilizing device and method for ploughing soil improvement, and relates to the technical field of ploughing fertilization, the fertilizing device comprises a tumbril, and the top end of the tumbril is fixedly connected with a stirring mechanism. By arranging the discharging mechanism, after soil is shoveled into the mixing barrel by the soil turning mechanism, liquid fertilizer in the fertilizer box is scattered into the mixing barrel under the driving of the mixing mechanism, the soil sprayed with the fertilizer is stirred by a stirring plate, so that the fertilizer is added more uniformly and fully, and then the soil mixed with the fertilizer is scattered into a field through a screen; by arranging the stirring mechanism, fertilizer particles are scattered in the moving process of the tumbril, fertilizer is stirred, the situation that the fertilizer is agglomerated to affect the fertilization effect is prevented, meanwhile, the rotating shaft drives the mixing mechanism to move,
