发明名称 Method and apparatus for growing nursery stock in subterranean containers
摘要 A method of growing nursery stock in-field, in reusable, permanently buried containers, combining the advantages of both container and in-field planting techniques. Apparatus for practice of the method includes an in-ground container with root-escapement apertures, and a harvesting tool conforming to the shape of the container which coacts with the container to facilitate removal of a plant and its root ball from the container, while leaving the container buried in the ground.
