Automatic inter-seedling supplementary seeding and fertilizing equipment

The invention relates to the technical field of reseeding and fertilizing equipment, and discloses inter-seedling automatic reseeding and fertilizing equipment which comprises a frame, reseeding mechanisms are fixedly mounted at the top and the bottom of the frame, and a digging mechanism, a land leveling assembly and a fertilizing mechanism are fixedly mounted at the bottom of the frame. According to the automatic inter-seedling supplementary seeding and fertilizing equipment, a third driving motor and a driving plate are driven by a threaded rod to descend under the limitation of a limiting rod, a bottom inserting seed conveying head descends and is inserted into the ground, a second driving motor and a material conveying spiral disc rod convey seeds into a hollow seed conveying column, a first driving motor and a second driving roller rotate, and under the transmission of a transmission belt, the seeds are conveyed into the hollow seed conveying column; a transmission roller I drives an incomplete gear to
