避雨栽培对‘赤霞珠’葡萄果实品质影响的对比研究

笔者采用避雨栽培的方法改变‘赤霞珠’葡萄果实生长小环境，通过对比测定露地及避雨栽培赤霞珠葡萄果实的糖、酸、酚类等指标，研究避雨栽培条件对赤霞珠葡萄果实品质的影响，从而为改善葡萄生长期间的栽培管理，培育优质酿酒葡萄提供理论依据。结果表明：避雨栽培条件有利于糖分的积累、有机酸的分解及多酚物质的形成，但由于避雨棚对光照的影响，却不利于花色苷的形成。因此，避雨栽培条件下改善光照条件，将对提高果实品质具有重要意义。

The Comparative Study of Rain-shelter on Fruit Quality of Cabernet Sauvignon

In this study,the author adopted the rain-shelter method to change the small environment of Cabernet sauvignon fruit,sugar,acids,phenols and other indicators were measured by comparing the open field and Cabernet sauvignon grapes cultivated by rain-shelter to study the rain-shelter on fruit quality of Cabernet sauvignon grapes,so as to improve the cultivation and management during the grape growing,and provide a theoretical basis for cultivating high-quality grapes.The results showed that:rain-shelter culti...
