The present invention relates to a drip irrigation hose including: a plurality of unit pressure-reducing channels each secured to the inner wall of the hose at longitudinally-spaced locations along a length of the hose in such a manner as to form an integrated type pressure-reducing channel; and a plurality of outlets for discharging water at longitudinally-spaced locations along the length of the hose, each of the plurality of unit pressure-reducing channels comprising an inlet part having a plurality of inlets formed at the left and right sides thereof, an inducing groove part connected to the inlet part and having a plurality of flow passageways formed in such a manner as to be reduced and enlarged in turn in the width thereof and a plurality of crescent-shaped protrusions formed in the flow passageways enlarged in the width thereof for reducing water pressure while the water flowing thereinto collides therewith, and a staying groove part connected to the inducing groove part and having a large space formed for making water flowing from the inducing groove part stay at stable pressure for a short time of period just before the water is discharged through each of the plurality of outlets to the outside of the hose.
