Abstract
This study evaluates the effectiveness of hydrogel application in improving the growth, survival, and water-use efficiency of saxaul (Haloxylon spp.) under drought conditions. Hydrogel treatments were compared with traditional planting methods under arid conditions characterized by high temperatures and limited precipitation. Different hydrogel application rates were tested to determine their effects on soil moisture retention, seed germination, seedling survival, root development, and biomass accumulation. The results showed that hydrogel significantly improved soil water availability and plant performance compared with the untreated control. Application rates of 2–3 g/kg soil produced the most favorable responses, with 2 g/kg showing particularly effective survival and root development. These findings demonstrate that hydrogel-assisted planting can provide an efficient approach for saxaul establishment, water conservation, and restoration of drought- affected arid ecosystems.References
