SPIRAL CLOSED CONDUIT FOR CULTIVATION

摘要

The present invention relates to a spiral underdrainage pipe for a plant cultivation, more specifically to the spiral underdrainage pipe for plant cultivation which improves a water pipe supply and a water drainage efficiency while increasing a recyclability of the underdrainage pipe, by using the underdrainage pipe capable of performing both the water pipe supply and water drainage processes and the recycling process simultaneously during the cultivation of plants. The present invention, the underdrainage pipe which is buried underground during plant cultivation, comprises: a long member that is wound in a spiral shape to form the underdrainage pipe; and multiple protrusions which are formed on a surface of the long member to form gaps between the connected adjoining members.
