摘要
调查了大泽山葡萄产地地球化学环境,研究了土壤、植株及植株中元素迁移富集规律。结果表明,土壤元素有效量与葡萄植株元素含量有一定的相关性,叶片与叶柄中元素有很好的相关性。不同葡萄品种间植株中个别元素含量有显著的差异,叶片、叶柄元素含量均远远高于果实。元素在植株和葡萄中的分布,只与元素性质有关,与葡萄品种无关。大泽山葡萄园土壤达到了国家果园土壤环境质量一级标准。土壤中镁与钙的有效量分别与葡萄酸度和甜度密切相关。
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 soll quality in Dazeshan graperies meets the flrst-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.
