ROOT-PROOF WATER-SUPPLY STRING AND METHOD FOR MANUFACTURING ROOT-PROOF WATER-SUPPLY STRING

摘要

A root-proof water-supply string being a flexible string composed of a capillary material having a capillary function and a root-proof and water-permeable material which has a water-permeability and a root-proof function and covers the entire outer periphery of the capillary material. A method of manufacturing a root-proof water-supply string including the steps of winding a root-proof and water-permeable material around a capillary material, overlapping the end parts one on the other and then fixing the end parts together.
