| 中文摘要: |
| 为探究微生营养激励素（SS-NB）对大豆光合作用、根瘤生长和大豆营养品质的影响，本研究设置CK（对照）、CF（化肥）和SS-NB（微生营养激励素）3个处理组，评价了大豆品质并分析了大豆籽粒代谢差异。结果表明：施用SS-NB后，大豆光合作用显著增强，根瘤数量和鲜质量分别较 CF提高 97.87%和 42.40%。施用 SS-NB显著上调了大豆籽粒中营养物质的富集，不饱和脂肪酸含量较CF提高8.96%。SS-NB处理组的大豆加工所得食用油能够有效降低动脉粥样硬化风险和血栓形成风险，更有利于人体健康。此外，施用SS-NB还上调了氨基酸代谢、脂肪酸代谢和类黄酮生物合成等代谢途径，提高了大豆中抗氧化物和植物激素的丰度，上调了大豆籽粒中植物次生代谢物的丰度。研究表明，SS-NB可通过调控大豆代谢途径促进大豆营养品质提升。 |

| Microbial nutrient stimulant（SS-NB）recovered and extracted from activated sludge using alkali thermal hydrolysis technique contains abundant nutrients and biostimulants, which can promote crop growth and have promising applications in solid waste resource utilization and soil improvement. In this study, three treatment groups, CK（blank control）, CF（chemical fertilizer）, and SS-NB （micronutrient stimulant）, were established to investigate the effects of SS-NB on photosynthesis, nodule growth and nutritional quality of soybean, and the soybean quality and differences in soybean seed metabolism were further evaluated. The results demonstrated that SSNB considerably improved soybean photosynthesis, with nodule numbers and fresh weights increasing by 97.87% and 42.40%, respectively, as compared to CF. SS-NB significantly increased nutrient enrichment in soybean seeds, with an 8.96% increase in unsaturated fatty acid content compared to CF. The edible oil processed from soybeans in the SS-NB treatment group can effectively reduce the risks of atherosclerosis and thrombosis, offering enhanced health advantages for human populations. Furthermore, SS-NB up-regulated amino acid metabolism, fatty acid metabolism and flavonoid biosynthesis, increased the abundance of antioxidants and plant hormones in soybean, and increased the abundance of plant secondary metabolites in soybean seeds. The study shows that SS-NB promotes the improvement of soybean nutritional quality by regulating the soybean metabolic pathway. |
