DELAYED DEGRADABILITY DRIP IRRIGATION PIPE

摘要

A delayed degradability drip irrigation pipe including a water conduit at a water conduit pressure and a plurality of drip irrigation outlets, each communicating with the water conduit and providing a water output at a pressure below the water conduit pressure, at least the water conduit being formed at least partially of a degradable material and also including a degradability delayer which provides a desired delay prior to failure of the water conduit but permits eventual degradation of the degradable material under predetermined conditions.
