PURPOSE: To obtain the structure of a hose for supplying water to an underground root region in the culture of plants in a green house, easy in the production of the structure, and capable of being produced at a low cost. ;CONSTITUTION: The structure of a hose for supplying water to an underground root region in the culture of plants in a green house is obtained as follows. A large tube 1 and a small tube 2 integrally connected to each other through a connecting member 3 are formed from poly(vinyl chloride) by an extrusion molding method, and thick holding belt parts 4a, 4b are formed at a part of the large tube and at a part of the small tube, respectively. Communicating holes 5, 6, 6a are perforated in the holding belt parts, respectively, at a prescribed interval. A cramp-like bypass tube 7 is inserted into the hole perforated in the holding belt part 4a of the large tube 1 and into the communicating hole perforated in the holding belt part of the small tube. The water tube of a water-supplying device is inserted into the communicating hole 6 perforated in the holding belt part 4b of the small tube 2.;COPYRIGHT: (C)1996,JPO
