Saline soils pose complex environmental challenges that limit fruit tree root function. Understanding the mechanisms by which factors drive traits in zone soil is crucial for improving productivity through irrigation-based regulation of structure. This study aimed to identify primary drivers and driving environment on traits, as influenced water content saline trees. A 2-year field experiment was conducted Korla, Xinjiang, investigate effects physicochemical properties, enzyme activities, nutrients active state trace elements setting different irrigation gradients (Low: 3750 m 3 ha −1 ; Moderate: 5250 High: 6750 ). Compared low-irrigation treatment, results showed high-irrigation treatment decreased electrical conductivity pH 21.6–30.5 % 1.4–5.5 %, respectively, increased organic matter, available phosphorus, potassium 4.4–5.1 11.7–17.6 14.8–34.6 respectively. Additionally, catalase, urease, phosphatase activities 30.0–33.1 21.6–22.0 30.0–30.2 enhancing amount promote nutrient migration deeper layers providing a stable suitable main zone. Concurrently, total dataset (TDS) established using four categories 15 indicators, including nutrients, elements, 0–80 cm soil. The machine learning models were used screen reveal mechanism traits. Random Forest model identified phosphatase, effective temperature with an increase MSE (%) range (10.3–15.6 %), AP (6.8–10.9 (8.3–16.9 %). water-mediated had positive effect Therefore, this provides theoretical basis programs • ·ha increasing SOM 40–80 range.

ABSTRACT The traits of root xylem play important roles in plants through the provision structural support, nutrient uptake, and water transport. However, relationship between hydraulic plant growth performance drylands remains unclear. In this study, 35 perennial forbs on Loess Plateau were obtained field surveys anatomy experiments. results revealed that was significantly correlated with anatomical traits. vessel fraction (VF), mean area (MVA), theoretical conduction diameter (Dh), transfer efficiency (MKp) increased age forbs. Higher Dh, MVA, MKp observed to increase rates heights main stems, which virtually unaffected by number (NV). Since MKp, NV for rate, more reliable predictors rate. This study taproots influenced performance, especially drylands. Further, we highlighted relationships roots provided insights into survival strategies management vegetation water‐limited regions.

Many studies have investigated how soil water availability in shallow affects forest transpiration, but deep status (below 1 m depth) alters tree use remains poorly understood. To improve our understanding of changes transpiration dynamics, we measured content (SWC) more than 20 depths, the radial sap flow profile and leaf area index (LAI) 2017 growing season 9-, 12-, 16-, 19- 23-year-old afforested apple (Rosaceae) trees on Chinese Loess Plateau. SWC was also long-term cultivated farmland to derive before afforestation. The results showed that there no statistical difference among orchards (p > 0.05), while reduced rapidly with increasing age. average at 1–20 decreased from 0.27 ± 0.02 cm3 cm−3 0.21 0.03 orchard. Moreover, storage by 139 mm yr−1 between 9- 12-year-old stands, 105 12- 16-year-old 44 16- 19-year-old 9 indicating gradually has restricted use. Due SWC, growing-season LAI peaked orchard then stand Growing-season only 77% 16-year despite older having larger diameters breast height. Our suggest plays an important role regulating trees’ transpiration.
