Abstract

Alhagi sparsifolia Shap. is one dominant plant species in the desert-oasis transitional zone on the southern edge of Taklamakan Desert, which plays an important role in windbreak and sand fixation as well as in husbandry development. In this paper, a controlled experiment was conducted over the root architecture and biomass distribution of A. sparsifolia Shap. seedlings in the growth season. The results showed: Root biomass: from July to October, aboveground biomass, underground biomass and total biomass of the seedlings varied with different irrigation gradients: 0m3/m2 > 0.2m3/m2> 0.1m3/m2; root/shoot ratio also showed similar variation pattern: 0m3/m2> 0.2m3/m2> 0.1m3/m2 biomass could be described with an S-shaped logistic curve.
