Abstract：Haloxylon ammodendrom is an excellent tree species in northwest China for windproof/prevention， sand fixation，and ecological balance protection.However，the dry climate and high summer temperatures in the arid desert areas of northwest China severely affect the growth and development of H .ammodendromseedlings.To explore the suitable planting methods for the growth of the seedlings，this study used 1-year-old H. ammodendron seedlings as experimental subjects and set up 5 diferent doses of super absorbent polymers （ 1，2，3，4 g）and 4 planting depths（20，40，60， 80cm ）for combination treatments.The changes in stomatal morphology and anatomical structure of H. ammodendron after different planting treatments were studied. The results showed that with the increase of water retaining agent dosage and planting depth，the stomatal length， stomatal width，stomatalarea，and thickness of various anatomical structures of the seedlings showed a trend of first increasing and then decreasing.The pore density shows a trend of first decreasing and then increasing. Stomatal length，stomatal width，stomatal area，diameter of assmilating branch，stratum corneum，palisade tissue，water storage tissue，vascular column thickness，and duct aperture were allthe largest，while stomatal density was the smallest when treated with 3g super absorbent polymer and 60cm planting depth. The application of suitable planting treatments can create a better growth environment for H. ，ammodendron. When facing environmental stress，it can improve plant stressresistance and effectively alleviate the impact of stress on plants.
