PURPOSE: A multifunctional irrigation hose is provided to prevent a fluid path conduit line from being removed by pulling a cover plate when a main body pipe is expanded. CONSTITUTION: A main body pipe (20) includes spraying holes spraying water to the outside on the upper surface of a hollow unit (21) for transferring water. A cover plate (30) covers the upper side of the main body pipe, prevents the disperse of the water sprayed from the spraying holes, and discharges the water in drops. The cover plate includes an attaching unit partially attached to the upper side of the main body pipe to the longitudinal direction. A jet hole (22) is formed on both side of the attaching unit on the main body pipe. An upper jet hole (221) and an upper side jet hole (222) are formed on the upper side surface of two cover plates.
