Abstract:

In this study, the wet digestion method was used to treat soil samples from five vineyards in Hebei Changli grape-producing area. The contents of four metal elements such as copper, iron, zinc and manganese in grape, grape wine and vineyard soil samples were detected by flame atomic absorption spectrometry. Results showed that the contents of four metals were significantly different in soil samples and grape samples with different varieties, age and postures from different vineyard locations and microenvironments. The contents of iron, zinc and manganese in soil of vineyards reveal a correlation with the contents of three metal elements in grape. There was a similar trend in the contents of copper, iron, zinc except manganese between the soil and grape wine from three kinds of grapes such as Cabernet Sauvignon, Merlot and Syrah.
