Abstract
The irrigation hose comprises two tubes disposed one within the other, at least one of the tubes being grooved. The ungrooved tube forms with the groove or grooves of the other tube continuous secondary ducts over the entire length of the hose. Inlet ports and outlet ports delimit in the secondary ducts sections of a predetermined length, each yielding a flow capable of continuously drip-irrigating a plant in the area to be irrigated. The outlet ports and the inlet ports are distributed along spiral lines if the secondary ducts are straight and along straight lines constituting generatrices of the hose if the secondary ducts run along spirals.
