发明名称 Plastic planting container
摘要 A plastic container for planting tree seedlings in a mechanized process, and being in the shape of a projectile suitable for penetration into soil. The planting container is highly oriented in its longitudinal direction with a number of longitudinal grooves positioned on the inside, outside or both sides thereof. The grooves include slits and holes to permit drainage, egress of growing roots, and aiding in the self-destruction of the container after being injected into the ground with a seedling. The self-destruction can be further promoted by the use of stress cracking agents within the plastic material comprising the planting container.
