ABSTRACT:
A container for the cultivation of little wooden nursery plants, which container is composed of a material derived from hydrocarbons, as for example polyvinyl chloride (pvc), characterized in that across the opening of the same passes a crosspiece with a central hole, also having vertical and horizontal bands that are needed to hold the container in an erected position, which new container has many important functions: to help the little plant to grow, but favoring the extension of the lateral roots, while the main-root will be atrophized, finding on the closed end of the container an obstacle that blocks its growth, and therefor avoiding the cutting of the main-root; to indicate to the purchaser the approximate age the plant has reached in the nursery, from the seeding up to the selling; to protect the roots by preserving around them the clod of original earth.
