Due to its sensitivity cold temperatures, cucumber growth is substantially constrained by suboptimal temperature stress in northern China’s off-season production systems. Suboptimal temperatures severely repress the nutrient absorption, growth, and yield formation of vegetables solar greenhouses during winter early spring China. Alginate oligosaccharides (AOSs) are anionic acidic polysaccharides derived from brown algae, known for promoting plant alleviating abiotic stress. In this study, we aimed investigate effects different solution concentrations combined with AOS on uptake seedlings under (15/8 °C, day/night). Potted ‘Jinchun 4’ grown coconut coir were treated 0.5×, 1.0×, or 1.5× strength Hoagland alone (N0.5, N1, N1.5), 30 mg·L−1 (A0.5, A1, A1.5). The results showed that attributes nitrogen (N) accumulation plants N1 N1.5 significantly higher than those N0.5. Additionally, A0.5 exhibited height, chlorophyll a content, root surface area, volume, vitality, N metabolism enzyme (NR, GDH, GS) activities, accumulation, N0.5, N1.5. Moreover, compared A0.5, net photosynthetic rate, total length, leaf nitrate reductase activity, glutamate dehydrogenase A1 A1.5 A0.5. Correlation analysis revealed strong linkages between morphology traits tissue content. summary, conditions, application improved seedlings’ absorption more efficiently merely raising levels, as it enhanced metabolic activities.
