| Abstract: |
| Water consumption of three-year old young jujube trees were investigated using pot experiment in Akesu, Xinjiang. The trees were irrigated with the same irrigation schedules under five treatments: 20 mm(C1), 25 mm(C2), 30 mm(C3), 35 mm(C4), 40 mm(C5). The results showed that the daily water consumption of each plant under different treatments was 1.09~3.45 mm in C1, 1.40~4.00 mm in C2, 1.56~4.50 mm in C3, 1.87~5.21 mm in C4 and 2.01~5.59 mm in C5, and the water consumption increased with the irrigation amount; the cumulative water consumption during the whole growth period was 368.6~635.1 mm. Water consumption modulus at the flowering stage was significantly higher than that at other stages, changing between 36.6% to 38.1 %. The jujube fruit yield and water use efficiency increased with the irrigation amount when the irrigation was between 20 mm and 35 mm. With the irrigation increasing from 35 mm to 40 mm, the jujube fruit yield and water use efficiency decreased. The jujube fruit yield of each treatment showed significant difference at 0.05 level, and the highest yield and water use efficiency was when irrigation was 35 mm. |
