| Abstract: |
| It is very important to study the water consumption characteristics and growth features of Halaxylon ammodendron under water stress for determining sacsaoul eco-water requirements in the Junggar Basin in Xinjiang. Based on the tub-cultured experiments, the features and relations between water consumption and growth of Halaxylon ammodendron were studied under different water stress treatments. The results showed that the longer the time required
by Halaxylon ammodendron to adapt to the water environment was, the more deeply the degree of water stress was. The lowest water consumption of Halaxylon ammodendron was 50 mm and Halaxylon ammodendron grew slowly when its water consumption was beyond 150mm. Halaxylon ammodendron logarithmically grew approximately with its water consumption under water stress. The facts that Halaxylon ammodendron's canopy grew quickly than its branches indicated that water was very beneficial to the Halaxylon ammodendron’s canopy growth comparing with the Halaxylon ammodendron's branches growth. These results are helpful to evaluating the lowest eco-water requirements of Halaxylon ammodendron. |
