Abstract: This paper reports a study of the effects of different treatments (spring mowing, spring firing, autumn mowing, and a contrast test) on the growth and physiological characteristics of Alhagi sparsifolia in the southern fringe of the Taklimakan Desert. The results show that under autumn mowing the leaves were significantly thicker and had a higher ratio of leaf length to width, indicating increased capability to transfer energy and material compared to the other treatments. All the treatments reduced A. sparsifolia plant growth and regeneration. However, mowing in autumn showed the strongest regenerative capability of the three treatments. Autumn mowing produced leaves with significantly higher photosynthetic pigment content than the other treatments. All three treatments reduced the physiological damage to A. sparsifolia from the external environment, though mowing in autumn showed the strongest resistance. The paper thus concludes that autumn moving is the best management practice for A. sparsifolia.
