“…Our study data shows that the proportions of clay (particle size < 0.002 mm) and clay minerals in saline‐alkali soil are 5.47–12.43% and 7.00–19.04%, respectively (Tables 1 and 3), indicating that the mineral composition and particle size distribution of these soils are not primary factors contributing to the poor permeability of these soils. Our results were similar to the analysis of saline‐alkali soil microstructure of different land‐use types in the Yellow River Delta by Liu, Li, Geng, and Li (2020). However, a study found that the low permeability of saline‐alkali soil in the Yellow River Delta is mainly due to the large amount of clay particles, and added Yellow River sediment to change the particle size distribution to remediate the saline‐alkali soil (Mao et al, 2016; Mao et al, 2018).…”

In the Yellow River Delta of China, soil salinization is of serious concern from both agricultural and environmental perspectives. In this study we investigated the microstructural characteristics of saline‐alkali soils in this region and explored the influence of frost heave on soil microstructure. Soil mineral composition, pore distribution, particle arrangement, and pore characteristics were measured using X‐ray diffraction (XRD), mercury intrusion porosimetry (MIP), and scanning electron microscopy (SEM). Soil pore characteristics, overall porosity, and unconfined compressive strength (UCS) were measured at water content of 10, 15, 20, 25% (w/w) before and after freezing at −10°C. The results showed that deterioration of soil physical properties was largely caused by dense particle arrangement, high proportion of ultra‐micropore‐specific surface area, and poor pore distribution, rather than mineral content or particle size distribution. The microstructure of saline‐alkali soil was greatly improved by frost heave with the overall porosity and UCS of frost heave‐treated soil samples significantly higher than for the control. Moreover, particle cementation decreased with increasing soil water content. This study demonstrated that a combination of XRD, SEM, and MIP offers accurate evaluation of the microstructural characteristics of saline‐alkali soils, and frost heave may serve as an economically sustainable and technically feasible method for saline‐alkali soil amelioration in the Yellow River Delta.

“…Previous research investigations generally indicate the saline-alkali soils are typically featured with low soil hydraulic conductivity and poor soil structure [39,40] . Similarly, our recent research indicated that the low permeability of soil in the Yellow River Delta is caused by its deteriorated microstructure, which may not be related to its mineral composition [4,[35][36][37][38] . In line with the conclusion, our experimental data showed that the saturated hydraulic conductivity of saline-alkali soil was 3.58×10 -5 cm/s (Table 1), and soil infiltration time was 170 min for CK (Figure 2).…”

“…Soil salinization is one of the major problems in global agriculture because it can lead to soil degradation and undermine the productivity of cultivated land [1,2] . The global saline-alkali land area accounts for about 10% of the total land area [3] , while the wasteland caused by salinization is about 34.6 million hm 2 in China [4] . Typical physical features for saline-alkali soil include non-ventilation and poor water permeability, which severely restricts the ecological reservation as well as economic and social development [5,6] .…”

Soil salinization is an issue of global concern. Despite recent evidence indicates that application of sediments into saline-alkali soil in Yellow River Delta as an additive can increase crop yield, its effects on soil structure and infiltration remain uncertain. In this study, the comprehensively analyses were conducted on the soil infiltration and microstructure of the soil treated with three sediment application layers (surface layer at 0-15 cm, lower layer at 15-30 cm, and plough layer at 0-30 cm) and four sediment incorporation rates (0, 2%, 5% and 10%), using soil column simulation experiment. Results indicated that the dredged Yellow River sediments can improve the infiltration capacity of saline-alkali soil; and the infiltration capacity increased with the rising sediment incorporation rate under the given application pattern. Compared with the control, applying dredged Yellow River sediments at 10% rate at lower layer and plough layer significantly facilitated the soil infiltration of the saline-alkali soil. Soil macro-porosity for T2, T5 and T10 was 26%, 52% and 158% more than that for the control, respectively. This phenomenon was attributed to the increased soil macro-porosity, due to the improved soil microstructure with the incorporation of sediment into the saline-alkali soil. Moreover, the cumulative infiltration was fitted better with Kostiakov infiltration model than Horton and Philip models.

“…Besides, asparagus also has strong ecological values. Its strong salt‐alkali resistance property enables asparagus to grow normally in soil with less than 0.3% salt content (Chen et al., 2014 ; Gao et al., 2021 ; Zhang et al., 2020 , 2022 ), and its sophisticated root system makes it effective in preventing soil erosion (Li et al., 2020 ).…”

Asparagus, a vital economic contributor, is a well‐liked vegetable grown around the globe, and some secondary metabolites in its spear are beneficial to human health. Asparagus spears possess a significant quantity of nutrients and phytochemicals; however, the difference in these chemical compositions among various varieties has not been sufficiently studied. This work aimed to detect the chemical compositions of 30 varieties of asparagus and to assess them by principal component analysis (PCA). The results showed that the contents of these chemical compositions varied in varieties. Selenium (Se, 1.12–2.9 μg/100 g dry‐weight [DW]) was abundant in asparagus, with an average dry matter content of 8.25%. Free amino acids (5.60–9.98 g/100 g DW) and polyphenols (6.34–8.67 mg/g DW) were both present in high amounts, along with flavonoids (4.218–8.22 mg/g DW) and protodioscin (0.44–1.96 mg/g DW). Correlation analysis, PCA, and hierarchical cluster analysis were used to conduct a comprehensive evaluation of asparagus. Atlas, Appolo, Jinggang 111, Jingke 2, and WS‐1 were the top five varieties with comprehensive scores. This study provided valuable data for the breeding, quality improvement, processing, and utilization of asparagus varieties in the future.
