Abstract

Abstract A plant cultivation device comprised of a plurality of walls positioned parallel to each other and vertically inserted into the soil. Adjacent parallel walls are connected by a corrugated plate which has drainage holes positioned within parallel grooves on the plate. Hot water pipes are positioned within these grooves for supplying heat to the surrounding area. A layer of wood chips covers the hot water pipes and corrugated plate. The wood chip layer is in turn covered by a layer of cultivation soil. Steam discharge pipes are positioned adjacent to the partition walls at a point above the cultivation soil and are covered by a shield which interconnects to adjacent walls. High pressure steam sterilizes the air and soil and thus promotes the healthy growth of plant life.
