“…Therefore, this study used RM, RL, RA, RV, tips, LA, and 10 other indicators to identify the drought tolerance of the different species; these indicators have been widely used (Qiao et al, 2019;Zhang, Shi, Wang, & Zhao, 2018). The subordinate function method can synthesize multiple indicators for scientific evaluation (Xia et al, 2019). In this study, we adopted the Note: Seven root traits were used for factor analysis using the principal component analysis (PCA) extraction method.…”

Gramineae and Leguminosae forages are widely grown in the semiarid region of northwest China. To understand the changes in root morphology in forage seedlings under drought stress, a nursery experiment was conducted with and without water stress using four Gramineae species (Bromus inermis, Agropyron mongolicum, Lolium perenne, and Bothriochloa ischaemum) and four Leguminosae species (Lespedeza bicolor, Medicago sativa, Astragalus adsurgens and Melilotus suaveolens). The forages were grown in rhizoboxes under drought stress (15% polyethylene glycol stress) and well-watered (85% of field capacity) conditions. The results showed that the root length, root area, and specific root length of the Gramineae species were higher than those of the Leguminosae species at the 30-60 cm soil depth. The fine roots of eight species in the 0~0.5 mm diameter class had the largest total root length and total root area, and the total root volume and root tips in the 0.5~1.0 mm diameter class were the highest. Based on the subordinate function method results, B. inermis had the highest comprehensive score, while M. suaveolens had the lowest. Our results implied that Gramineae seedlings distributed more roots than Leguminosae seedlings in the 30-60 cm soil layer under drought stress. Under drought stress, fine roots in the 0~0.5 mm and 0.5~1.0 mm diameter classes were the main organs sustaining the growth of the eight species when suffered drought stress. Among the eight species, B. inermis had the strongest drought tolerance and could act as an optimal ecological restoration forage in the semiarid region of northwest China.

“…It is well known that the soil is critical to maintaining the productivity and sustainability of forest ecosystems, and the ability of forest soil to store and transform organic material is in uenced by the soil organic matter, which can be in uenced by forest vegetation types (Liu et al 2018;Xia et al 2019). Therefore, knowledge about the soil nutrients in different forest soils is of great importance to understanding biogeochemical cycles (Yang et al 2010).…”

Background: Large-scale afforestation can significantly change ground cover and soil physicochemical properties, especially the soil fertility maintenance and water conservation function of artificial forest is very important in semi-arid mountain ecosystems. To better understand the effects of different tree growth on soil nutrient and soil physicochemical properties following afforestation to determine the best plantation tree species for improving soil fertility and water conservation functions. Methods: This study investigated the soil nutrient contents for three different tree species (Larix principis-rupprechtii, Picea crassifolia, Pinus tabuliformis), soils and plant-soil feedbacks, as well as the interaction between soil physicochemical properties. Results: The results revealed that the leaf and litter layer strongly influences soil nutrient availability through biogeochemical processes: P. tabuliformis has higher organic carbon, C:N and C:P in the leaves and litter layer than L. principis-rupprechtii or P. crassifolia, suggesting that higher C:N and C:P hinder litter decomposition. As a result, the L. principis-rupprechtii and P. crassifolia plantation forests significantly improve soil nutrients and clay component than P. tabuliformis plantation forest. Furthermore, the the L. principis-rupprechtii and P. crassifolia plantation forests significantly improved the soil capacity, soil total porosity and capillary porosity, decreased soil bulk density, and enhanced water storage capacity than P. tabuliformis plantation forest. In conclusion, the results of this study show that the strong link between plants and soil is tightly coupled to C:N and C:P, and there had strong correlation between soil particle size distribution and soil physicochemical properties. Conclusions: Therefore, our results recommend planting the L. principis-rupprechtii and P. crassifolia as the preferred tree species to enhance the soil fertility and water conservation functions, especially in semi-arid regions mountain forest ecosystems.

Background: Large-scale afforestation can significantly change the ground cover and soil physicochemical properties, especially the soil fertility maintenance and water conservation functions of artificial forests are very important in semi-arid mountain ecosystems. However, how different tree growth affect soil nutrient and soil physicochemical properties following afforestation and which is the best plantation tree species for improving soil fertility and water conservation functions remain largely unknown. Methods: This study investigated the soil nutrient contents of three plantations with different tree species (Larix principis-rupprechtii, Picea crassifolia, Pinus tabuliformis), soils and plant-soil feedbacks, as well as the interaction between soil physicochemical properties. Results: The results revealed that the leaf and litter layer strongly influence soil nutrient availability through biogeochemical processes: P. tabuliformis has higher organic carbon, ratio of organic carbon to total nitrogen (C:N) and organic carbon to total phosphorus (C:P) in the leaves and litter layer than L. principis-rupprechtii or P. crassifolia, suggesting that higher C:N and C:P hinder litter decomposition. As a result, the L. principis-rupprechtii and P. crassifolia plantation forests significantly improve soil nutrients and clay components than the P. tabuliformis plantation forest. Furthermore, the L. principis-rupprechtii and P. crassifolia plantation forests significantly improved the soil capacity, soil total porosity, and capillary porosity, decreased soil bulk density, and enhanced water storage capacity than the P. tabuliformis plantation forest. In conclusion, the results of this study showed that the strong link between plants and soil is tightly coupled to C:N and C:P, and there had a close correlation between soil particle size distribution and soil physicochemical properties. Conclusions: Therefore, our results recommend planting the L. principis-rupprechtii and P. crassifolia as the preferred tree species to enhance the soil fertility and water conservation functions, especially in semi-arid regions mountain forest ecosystems.
