In April 2024, 16 soil pits with a width of 1 m, a depth of 1 m and a length of 5 m were dug in the test area. The pits were isolated with non-woven fabrics, and gravel soil, sand, and loam were backfilled respectively as test sample sites. The test adopted a randomized block design. The test area included groundwater irrigation area and oilfield reclaimed water irrigation area (including 3 soil treatments), with a total of 4 treatments, with 4 replicates for each treatment.\r\nOn April 20, 2024, Haloxylon ammodendron seedlings were planted, and the planting method was single plant hole sowing, with a row spacing of 2 m and a plant spacing of 50 cm. Drip irrigation was used, and different irrigation systems were used in different growth periods of Haloxylon ammodendron.\r\nIn mid-September 2024, a vertical soil profile was dug in the test sample plot, and samples were collected according to specifications at a location 30 cm away from the surface using a ring knife method. At the same time, the surface soil (0 - 20 cm) of the sample plot was mixed and collected according to the five-point sampling method. Following the principle of random sampling, 5 complete Haloxylon ammodendron plants were randomly selected from each sample site; the base diameter was measured with a digital electronic vernier caliper (accuracy of 0.01 mm), and the plant height was measured with a tape measure (accuracy of 0.1 cm); After the growth indicators were measured, the entire plant was excavated using destructive sampling method, cut from the base stem, and cut off the assimilated branches, stems and roots of each plant respectively and placed in envelope bags.", "ds_process_way": "1. Experimental Design\r\n\r\nThe study area is located in Baijiantan District, Karamay City (85°03′E, 45°61′N; elevation: 230 m). It has a typical temperate continental arid climate, with an average annual precipitation of approximately 108.9 mm and a long-term average annual evaporation of up to 3008.9 mm. The area experiences large diurnal temperature variations and a frost-free period of about 225 days. Natural conditions are relatively harsh, with frequent occurrences of extreme weather events such as high temperatures, cold waves, and strong winds. Historical extreme maximum and minimum temperatures have reached 48.6°C and −44.5°C, respectively. The annual average number of days with strong winds (above Beaufort Force 8) is 72.\r\n\r\nLoam, gravelly soil (gray-brown desert soil), and sandy soil, which are commonly distributed in the surrounding arid desert region, were selected as the experimental soils. Their properties are shown in Table 1. The irrigation water used in the experiment was reclaimed oilfield water treated by Karamay Oilfield Company, and its quality is presented in Table 2. To evaluate the effects of reclaimed oilfield water irrigation on plant growth, a groundwater-irrigated control treatment (loam soil) was established. The groundwater had a pH of 7.22 and a total salt content of 4.32 g·L⁻¹. One-year-old Haloxylon ammodendron seedlings grown from seeds were used for transplantation.\r\n\r\nA field experiment was conducted in a relatively flat saline-alkaline wasteland. In April 2024, sixteen soil pits measuring 1 m in width, 1 m in depth, and 5 m in length were excavated using an excavator. The pits were lined with nonwoven fabric around the edges and refilled separately with gravelly soil, sandy soil, or loam to serve as experimental plots. A randomized block design was adopted. The experimental area included a groundwater irrigation treatment and reclaimed oilfield water irrigation treatments (with three soil types), resulting in four treatments in total, each with four replicates. The layout of the experimental plots is shown in Figure 1.\r\n\r\nOn April 20, 2024, Haloxylon ammodendron seedlings were transplanted using single-plant pit planting, with a row spacing of 2 m and a plant spacing of 50 cm. Drip irrigation was applied, and irrigation schedules varied among different growth stages. Immediately after transplanting, irrigation was conducted once. During the early growth stage, irrigation was applied every 7 days at a rate of 10-15 L per plant. During the vigorous growth stage, irrigation was applied every 10 days at a rate of 5-10 L per plant. During the late growth stage, irrigation was applied every 15 days at a rate of 2-5 L per plant. All treatments followed the same irrigation regime and field management practices.\r\n\r\n2. Sample Collection and Measurements\r\n\r\nIn mid-September 2024, vertical soil profiles were excavated in the experimental plots. Undisturbed soil samples were collected at a depth of 30 cm from the soil surface using the soil core method according to standard procedures. Samples were sealed in bags and transported to the laboratory for the determination of soil moisture content, saturated water content, bulk density, porosity, and other parameters.\r\n\r\nAt the same time, surface soil samples (0-20 cm) were collected using the five-point sampling method and mixed to form composite samples. These samples were sealed in bags, transported to the laboratory, cleared of debris, and air-dried naturally. Total nitrogen content was determined using the Kjeldahl method; total phosphorus content was measured using the acid dissolution-molybdenum antimony colorimetric method; total potassium content was determined using the alkali fusion-atomic absorption flame photometry method; total salt content was measured by the gravimetric method; soil pH was determined using the glass electrode method; and petroleum hydrocarbons (C10-C40) were analyzed by gas chromatography according to HJ 1021-2019.\r\n\r\nFollowing the principle of random sampling, five intact Haloxylon ammodendron plants were randomly selected from each plot. Basal stem diameter was measured using a digital electronic vernier caliper (accuracy: 0.01 mm), and plant height was measured using a measuring tape (accuracy: 0.1 cm). After growth measurements were completed, destructive sampling was carried out. Entire plants were excavated and cut at the stem base. Assimilating branches, stems, and roots from each plant were separated, placed in labeled envelope bags, and returned to the laboratory. Samples were heated at 105°C for 30 min to deactivate enzymes and then dried at 70°C to constant weight. After weighing and recording, total plant biomass, biomass of individual organs, and biomass allocation among organs were calculated.\r\n\r\n3. Data Analysis\r\n\r\nData were entered and tabulated using Excel 2022. One-way analysis of variance (ANOVA), multiple comparison tests, and significance analyses were conducted using SPSS 26.0. Pearson correlation analysis was used to evaluate biomass allocation and its relationships with growth characteristics. Spearman correlation analysis was used to examine the relationships between biomass allocation and soil environmental characteristics.
