The distributor (2) includes a pattern of irrigation points with advantageously substantially constant surface pitch (6, 6') over most of the irrigation area, the pattern being, typically, regular in a main region of the distributor and irregular, with associated surface regions which are also irregular (6', 6'') in a junction region, the irrigation points delivering predetermined flow rates defined by calibrated orifices (4, 4', 4'') which have cross-sections chosen from a predetermined group of n cross-sections, n not being greater than four and advantageously not greater than two.
