英文摘要	Growth-promoting bacteria (GPB) have shown promising effects on serving plants against environmental constraints such as drought. Nevertheless, simultaneous effects of different GPB have less been considered for arid land plants and under field conditions. We investigated the effects of single and combined application of GPB, including free-living nitrogen-fixing bacteria (NFB), phosphate solubilizing bacteria (PSB), potassium solubilizing bacteria (KSB), a combination of NFB, PSB, and KSB (NPK), and control, at three drought stress treatments. In order to better understand the interactions between drought and GPB, we measured the morphological, biochemical, and physiological plant traits. The target plant was salt tree (Halimodendron Halodendron (Pall.) Voss), a legume shrub native to arid lands of Central and West Asia. All biofertilizer treatments enhanced the growth, physiology, and biochemistry of salt tree seedlings, and there were significant differences among the treatments. KSB and PSB treatments increased photosynthetic pigments, but KSB treatment was more efficient in transpiration rate and stomatal regulation and increased the soluble carbohydrates. PSB treatment had the highest effect on root traits, such as taproot length, root volume, cumulative root length, and the ratio of root to shoot. NFB treatment enhanced root diameter and induced biomass translocation between root systems. However, only the application of mixed biofertilizer (i.e., NPK treatment) was the most significant treatment to improve all plant morphological and physiological characteristics of salt tree under drought stress. Therefore, our results provided improvement of some specific plant traits simultaneous with application of three biofertilizers to increase growth and establishment of salt tree seedlings in the degraded arid lands.
