Abstract:

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 cultivation conditions was benefit to the accumulation of sugars, organic acids in decomposition and formation of polyphenols, but the impact of the rain-shelter shed light was not benefit to the formation of anthocyanin. Therefore, the change of light condition under rain-shelter cultivation would improve the fruit quality.
