| 英文摘要 | Water irrigation resources scarcity combined with the problem of poor quality of most of these resources known by their high salinity, present a great threat for the oasis agriculture sustainability. Hence, improvement of water saving technologies is imperative to ensure the better oasis productivity. The main objective of this work is to identify the efficiency of the irrigation technique for date palm trees through the assessment of irrigation technologies newly introduced by a few farmers in some of the Tunisian oasien regions. The three irrigation techniques, which were evaluated by applying the same volume of water irrigation under date palm trees, are the bubbler, the mini diffuser and the subsurface drip irrigation systems. The irrigation assessment showed that the uniformity in water irrigation distribution of the soil after irrigation is around 90% for the three techniques. The water irrigation losses after irrigation were 42, 63 and 72 mm, respectively, by bubbler, by mini diffuser and by subsurface drip irrigation. The irrigation water application efficiency is the best for the bubbler irrigation (62%). The water use productivity is also the highest for the bubbler (0.66 kg/m(3)); in addition to the desalination efficiency which was 63%. The results of this study showed that the bubbler irrigation system is the most efficient technique which will be the best technology practice under date palm trees in the Tunisian Oasis conditions. |
