The agricultural machinery fertilizing device with a fertilizer distribution rack stirs the fertilizer in the storage box through the rotation of the stirring rod, thereby improving the uniformity of the fertilizer in the storage box and indirectly improving the uniformity of fertilization. As the stirring rod rotates, the stirring rod crushes the fertilizer in the storage box, reducing the volume of the fertilizer in the storage box and reducing the possibility of blockage during fertilization, effectively improving the uniformity of fertilization and ensuring the growth-promoting effect of fertilization on crops.
