<p>PROBLEM TO BE SOLVED: To provide a hose for drip irrigation preventing clogging from forming in an outlets or an undesirable position. SOLUTION: In this hose for drip irrigation, the outlets from a flow control passage comprise longitudinal slits 46 and 47 formed by knife blades. The slits are sufficiently long enough and a film is sufficiently flexible enough so that water trickles from the outlets when the hose is pressurized. The slits are sufficiently short enough and the film is sufficiently rigid enough so that the slits completely close for preventing clogging when the hose is depressurized.</p> |
