【摘要】 为探讨全营养滴灌施肥对贺兰山东麓酿酒葡萄光合生理及产量、品质的影响，提出产质协同的营养调控技术。于2019—2021年采用单因素随机区组设计，设置常规施肥（CK）、CK+Si （T₁）、CK+Ca（T₂）、CK+Si+Ca（T₃）、CK+复合微肥（T₄）、CK+全营养肥（T₅）6个处理，研究中微量元素复配对酿酒葡萄光合特性、产量及其组成、品质等的影响。结果表明：与CK处理相比，T₁可显著提高酿酒葡萄叶片的净光合速率、气孔导度和叶绿素SPAD值，且分别提高了18.53%、13.63%和5.93%；配施中、微量元素均能提高酿酒葡萄的产量指标，且多元复配效果优于单元配施。T₅处理较CK处理相比，酿酒葡萄粒径、单果重、单穗长分别增加了6.26%、19.13%、51.56%;T₃处理下酿酒葡萄产量最高，为5576.35 kg/hm²；较CK处理相比，T₃处理下酿酒葡萄可溶性固形物含量最大，为28.94%;T₅处理可滴定酸的含量最低，为0.53%;T₂处理能显著提高酿酒葡萄总酚及单宁的含量，较CK处理相比分别增加14.70%、55.68%。综上所述，全营养滴灌施肥能够显著促进贺兰山东麓酿酒葡萄光合生理，实现产量、品质的协同提高。更多还原

【Abstract】 In order to explore the effects of full-nutrient fertigation on the photosynthetic physiology,yield and quality of wine grapes at the eastern foot of Helan Mountains in Ningxia,and propose a synergistic nutritional regulation technology for Ningxia,a single-factor randomized block design was adopted to conduct fertigation experiments from 2019 to 2021 with 6treatments,including conventional fertilization（CK）,CK+Si（T₁）,CK+Ca（T₂）,CK+Si+Ca（T₃）,CK+compound micro-fertilizer（T₄）,CK+full nutrient fertilizer（T₅）to study the effects of microelement complex on the photosynthetic characteristics,yield and composition,quality of wine grapes.The results showed that,compared with the CK treatment,（T₁ ）significantly increased the net photosynthetic rate,stomatal conductance and chlorophyll SPAD value of wine grape leaves by 18.53%,13.63%and 5.93%,respectively.The microelement complex increased the yield index of wine grapes,and the effect of multiple microelement complex were better than that of single microelement complex application.Compared with the CK treatment,the grain size,single fruit weight and single ear length of wine grapes increased by 6.26%,19.13%and51.56%in （T₅ ）treatment,respectively.The yield of wine grapes under （T₃ ）treatment was the highest at 5576.35 kg/hm².The soluble solid content of wine grapes was also the highest under the （T₃）treatment,which was 28.94%.The content of titratable acid was the lowest under T₅ treatment,which was 0.53%.The total phenol and tannin acid increased by 14.70%and55.68%under （T₂ ）respectively.In conclusion,full-nutrient fertigation can significantly promote the photosynthetic physiology of wine grapes at the eastern foot of Helan Mountains,and achieve a synergistic improvement in yield and quality.更多还原
