| 中文摘要: |
| 为明确油橄榄果渣酵素在水培韭菜栽培中的作用，本研究以油橄榄果渣为原料制备酵素，进而分析不同稀释浓度对其生长特性、产量及营养品质的影响，为油橄榄果渣在水培韭菜生产中的资源化应用提供技术支撑。本研究以改良霍格兰营养液为对照（CK），设置5个油橄榄果渣酵素稀释处理（100、300、500、700、900倍），测定不同处理下韭菜外部形态、产量、品质及抗氧化指标，并利用相关性分析和主成分分析评价油橄榄果渣酵素与水培韭菜产量及品质的关联性和关键影响因子。结果表明：酵素稀释300~700倍处理总体显著促进韭菜生长和品质提升，其中T3（500倍）效果最佳：与未添加酵素处理相比，株高、叶宽、假茎粗分别增加25.8%、29.0%、30.5%，地上部鲜质量提高48.3%，Vc含量增加177.8%，硝酸盐含量降低23.8%。此外，T3处理显著提高韭菜类黄酮、可溶性糖及矿质元素含量，并降低辛辣度。T1（稀释100倍）和T5（稀释900倍）处理对光合色素的促进作用较弱。主成分分析表明，株高，地下部干质量，Vc、可溶性蛋白、矿质元素含量是影响韭菜生长和品质的关键指标。研究表明，油橄榄果渣酵素在500倍稀释浓度下，能够显著促进水培韭菜的生长发育，提高其产量和品质，稀释过量或不足均引发负面效应。 |

| This study aimed to clarify the effects of olive pomace enzyme solution on the growth, yield, and nutritional quality of hydroponic Chinese chives, thereby providing a theoretical basis for the resource utilization of olive pomace in hydroponic production. A modified Hoagland nutrient solution was used as the control（CK）, and five dilution treatments of olive pomace enzyme solution were set（100-, 300-, 500-, 700-, 900-fold）. Morphological, physiological, quality, and antioxidant parameters of Chinese chives under different treatments were measured. Correlation analysis and principal component analysis（PCA）were performed to identify the relationships between olive pomace enzyme application, yield, quality, and key influencing factors. The results showed that, treatments with 300-700-fold dilutions generally promoted the growth and quality of hydroponic Chinese chives, with T3（500-fold dilution）showing the best effect. Compared with CK, plant height, leaf width, and pseudostem diameter increased by 25.8%, 29.0%, and 30.5%, respectively; shoot fresh mass increased by 48.3%; vitamin C content rose by 177.8%; and nitrate content decreased by 23.8%. In addition, T3 significantly enhanced flavonoid, soluble sugar, and mineral element contents, while reducing pungency. Conversely, T1 and T5 treatments had relatively weak promoting effects on photosynthetic pigments. PCA indicated that plant height, dry mass, vitamin C, soluble protein, and mineral element contents were the key factors influencing chive growth and quality. Olive pomace enzyme solution at a 500-fold dilution markedly enhances the growth, yield, and nutritional quality of hydroponic Chinese chives, whereas over - or under-dilution result in adverse effects. |
