【目的】为了探索不同土壤条件对酿酒葡萄生理及果实品质的影响,【方法】以‘蛇龙珠’酿酒葡萄为试材,研究了宁夏贺兰山东麓地区,黄河淤土、含石的沙壤土和风沙土3种土壤对葡萄糖分卸载的影响,测定了不同土壤栽培条件下葡萄果实的单果质量、可溶性固形物、可滴定酸、可溶性总糖、色素、单宁及葡萄叶片的光合速率。【结果】结果表明,在葡萄开始着色至葡萄完全成熟期间,在含石的沙壤土栽培条件下葡萄可溶性总糖含量(22.4%)比黄河淤土栽培条件下和风沙土栽培条件下分别高7%、9%;葡萄色素(5.14mg·g。)和叶片光合速率也最高,黄河淤土栽培条件下葡萄的含酸量(8.28g·L^(-1))和单粒质量(2.32g)较高,然而,风沙土条件下,单宁(籽单宁1.15mg·g^(-1),皮单宁0.30mg·g^(-1))的含量最高。【结论】土壤条件对酿酒葡萄果实品质影响较为显著,含石的沙壤土条件下葡萄品质最佳。
[Objective]The study was to elucidate the effect of different soil condition on physiology and fruit quality of wine grapes. [Method] 'Cabernet Shelongzhu' wine grape was used as experiment material to study the effect of soil conditions including the Yellow River silt, sandy loam with stone and aeolian sandy soil on grape sugar unloading , berry weight, soluble solids, titratable acidity, total soluble sugar, pigment, tannin and grape leaf photosynthetic rate. [Result]The results showed that during period from grape berry color change to full ripening ~ sugar content of grapes increased in sandy loam with stone by 7%, 9% than that in the Yellow River silt and aeolian sandy soil. Grape pigment content and grape leaf photosynthetic rate were also the highest under the condition of sandy loam with stone . Total titratable acidity (8.28 g. L^(-1)) and berry weight (2.32 g) in the Yellow River silt were higher than in other soil, and the tannin content (1.15 mg·g^(-1) in seed and 0.30 mg·g^(-1) in skin ) in aeolian sandy soil was the highest. [Conclusion] The studies suggested that effects of different soil condition on fruit quality of wine grapes is sig- nificant, fruit quality grown in the sandy loam with stone is the best.
