Abstract:
1. An irrigation pipe comprising: at least one first integrated irrigation emitter characterized by a first non-zero discharge-pressure threshold, whereby the at least one first irrigation emitter is capable of discharging water in response to a first non-zero water inlet pressure; and at least one second integrated irrigation emitter characterized by a second non-zero discharge-pressure threshold higher than the first discharge-pressure threshold, whereby the at least one second irrigation emitter is capable of discharging water only in response to a second non-zero water inlet pressure which is higher than the first non-zero water inlet pressure; wherein: the at least one first and at least one second integrated irrigation emitters are positioned along the irrigation pipe in accordance with a predetermined configuration; and the at least one first and at least one second irrigation emitters each comprise at least one labyrinth configured to provide resistance to water flow.
