Under-forest seeding machine capable of automatically controlling seeding distance and used for ganoderma lucidum planting

The invention relates to the technical field of ganoderma lucidum planting, and discloses a ganoderma lucidum planting under-forest seeder capable of automatically controlling the seeding distance, the ganoderma lucidum planting under-forest seeder comprises a planting machine, a power wheel, a ganoderma lucidum fungus bag and a driving assembly, the power wheel is rotatably connected to the bottom of the planting machine, the ganoderma lucidum fungus bag is arranged in the planting machine, and the planting machine is internally provided with the driving assembly for providing power for the ganoderma lucidum fungus bag; through the arrangement of a distance measuring rod and a distance increasing hollow cylinder, the purpose of automatically driving the distance increasing hollow cylinder to put ganoderma lucidum fungus bags after the distance measuring rod detects a deep pit is achieved, the inaccuracy of putting the fungus bags according to time in a traditional ganoderma lucidum seeding machine is avoided
