Abstract Aims Apple–soybean alley cropping is one of the typical alley-cropping models in Loess Plateau China. The study aimed to alleviate interspecific competition intensified by growth fruit trees using combination drip irrigation emitter line and mulching regulate soil nutrient distribution analyze effects on utilization. Methods A three-year field trial was conducted apple–soybean systems, setting up three spacings (L1: per soybean row; L2: for every two rows; L3: rows) methods (M1: mulching; M0: non-mulching). Results Rapidly available phosphorus (AP), rapidly potassium total contents varied greatly at same spacing, whereas AP content different spacings. Compared with M0, yield, use efficiency M1 significantly increased. Most nutrients denser spacing (L1) were concentrated surface layer uniform distribution. At wider (L3), uneven, resulting fewer uptake utilization roots. moderate (L2) alleviated optimizing facilitating root niche separation between crops. In years, M1L2 consistently displayed highest efficiency. Principal component analysis showed that achieved comprehensive score. Conclusions results recommended young L1 as a preferable control measure if M0 used.

Traditional dredged sludge disposal methods are characterized by low resource utilization and high carbon emissions, leading to serious environmental pollution. This study used sludge, composted pig manure, sawdust as raw materials, supplemented them with composite biological agents prepare improved soil. Plant adaptability the soil was comprehensively evaluated using factors such seed germination index (GI). The alkaline nitrogen content in increased 78.61% compared of other nutrients available potassium also varying degrees. Ryegrass GI 51.06% (IS1) sludge. main dominant fungi were Tausonia, Trichoderma, Cystoflobasidium, which promote nutrient activation antagonize pathogenic bacteria, making environment more conducive plant growth. Dredged successfully converted into planting Fully utilizing nitrogen, phosphorus, substances enriched provide for growth is an efficient method achieve utilization.

Extensive and unregulated groundwater extraction for irrigation in the arid inland basins of Northwest China has led to a continuous increase depth agricultural areas. This significantly altered distribution soil ions, making it difficult predict their evolution dynamic patterns. In this study, we used space-for-time substitution approach elucidate ion under changing depths. Experiments were conducted three typical areas with varying depths, that is, below 5 m, 5–10 above 10 m Korla, Xinjiang, China. Soil samples collected from five profiles at depths 0–180 cm measure moisture, salinity, major content. An innovative research framework was developed examine relationship between using ratios, principal components, hierarchical clustering, correlation analyses. aims reveal dynamics, correlations, mechanisms distribution, representative composition as increases The results showed increased, chemical type shifted Ca-SO4 Na-SO4 mixed types, an SO42− Na+ content profile. sodium adsorption ratio (SAR), total dissolved solids (TDS) higher shallow than deep groundwater. Groundwater negatively correlated cations anions (K+, Na+, Ca2+, Mg2+, Cl−, SO42−, NO3−). Meanwhile, positive exists CO32−. ions is primarily governed by influenced multiple factors. Evaporation dominant factor areas, whereas mineral rocks plays crucial role These findings provide scientific support strategic water-resource management policies sustainable development strategies regions.

This research investigates the influence of water–nitrogen coupling on soil water content, nitrogen dynamics, and root distribution in farmland, along with interactions among water, transport, distribution, crop yield. A field experiment was conducted under moderate drought stress (50–60% capacity) three application rates (100, 200, 300 kg·ha−1, split-applied at 50% during sowing jointing stage, labeled as N1, N2, N3) two critical growth stages (jointing stage P1 tasseling-silking P2) maize (Denghai 605). The results demonstrated that morphological parameters exhibited trend N2 > N1 N3 different treatments. Compared to low (N1) decreased by 35.01–49.60% average, whereas high (N3) led a reduction 49.93–61.37%. treatment consistently maintained greater uptake, highest yield 13,336 kg·ha−1 observed CKN2 treatment, representing increases 16.1% 9.2% compared P1N2 P2N2 treatments, respectively. Drought (P1) inhibited development more severely than (P2), demonstrating bidirectional adaptation strategy characterized deeper vertical penetration increased horizontal expansion imbalance. Correlation analysis revealed positive correlation between nutrient content indicators. At same time, characteristic values were significantly negatively correlated (p < 0.05). Appropriate management effectively stimulated growth, mitigated leaching risks, improved These findings offer theoretical foundation for optimizing production within Yellow River Basin.
