Device for protecting container-grown seedling root systems and method for its manufacture

摘要

A container-grown seedling protective device includes a flexible expanse including an array of generally cylindrical pods or pockets, each pod in the array of pods configured for holding a container-grown seedling root ball therein. Each pod is configured for holding a single seedling therein separate from one or more adjacent seedling root balls held by adjacent pockets, and each of the plural pods is detachably connected to an adjacent one of the plural pockets by a frangible web extending therebetween. Each pod can be perforated in at least a bottom region thereof to provide permeability and each pod can be infused with fertilizer of the like. A method for manufacturing a protective device for container-grown seedlings includes laying down a contiguous length of a first laminar film; positioning a plurality of spaced rods of defined length atop the length of first film; laying down a contiguous length of a second laminar film atop the first film and the spaced rods; adhering the first and the second films to form a seam along a congruent edge thereof beyond the reach of the rods and along plural spaced apart seams between the rods, the plural spaced apart seams extending from the congruent edge like teeth of a comb, thereby to form a contiguous laminate; and removing the rods from between the seams to form individuated substantially sealed plural pockets defined by the seams, the pockets being configured to receive therein root balls of container-grown seedlings.
