An investigation of geochemical environment for grape growth was conducted in Dazeshan grape-producing area. The regularity governing the movement and enrichment of elements in the soil-plant system was studied. The results show that there are certain relationships between elements in soils and in plants, and that elements in leafs are correlated well with those in leafstalks. Some elements vary considerably in different kinds of grapes with high levels in leafs and leafstalks. Elements in grape planks are distributed according to their chemical characteristics rather than to grape categories. The soil quality in Dazeshan graperies meets the first-rate demand of the National Soil Environmental Quality for Orchard. The effective quantity of Mg and that of Ca are correlated well with the acidity and the sweet for grape taste, respectively.
