The fertilizer mixing assembly includes a fertilizer tank. In use, soluble solid fertilizer is put into the fertilizer tank, water is filled into the fertilizer tank to pre-dissolve the solid fertilizer to form a mother liquor, and the prepared fertilizer mother liquor is mixed with irrigation water and then enters the irrigation pipeline system to be sprayed onto the planting crops through the pressure assembly, so that the irrigation and fertilization operation is completed after the processes of wetting, fertilization and flushing. The mixing method of the mother liquor and the irrigation water includes a main path type and a bypass type.

The rotation of the dispersion disc 23 drives the stirring wheel 36 to rotate, the stirring wheel 36 stirs the water and fertilizer to ensure the dissolving efficiency, and the rotation of the arc-shaped rod 33 driven by the dispersion disc 23 is accompanied by the descending of the arc-shaped rod 33, to change the position of the second water outlet hole 35, so that the water flow discharged from the second water outlet hole 35 to the inner wall of the fertilizer mixing cylinder 2 removes and dissolves the solid fertilizer remaining on the inner wall, to ensure the rated amount of solid fertilizer to participate in the dissolving process, to ensure the concentration of the fertilizer mother liquor, and to further improve the reliability of the water and fertilizer integrated machine in the case of short operation period and high water and fertilizer concentration control requirement in the fine irrigation operation.
