摘要： Soil nutrient characteristics are key factors that regulate grape growth and fruit quality. To investigate soil nutrient characteristics, 73 typical vineyards in Shanghai suburbs were selected for this study. The impacts of different planting areas, planting ages and grape varieties on soil characteristics were studied. The Agro Services International (ASI) analysis method was adopted to measure the levels of soil nutrients. The results indicated that soil nutrient characteristics varied greatly across the 73 selected vineyards in Shanghai suburbs. Planting area and planting age were the major factors that significantly affected soil nutrient characteristics. However, no significant differences were observed among the 5 major cultivated grape varieties. Significant differences in soil pH were only observed in different planting areas. Soil nutrients in the selected vineyards were mainly at a high level or extra-high level, which means that the current amount of fertilizer in these vineyards exceeds the actual demands of the grapevines and should be reduced. Meanwhile, the intermediate soil organic matter (OM) content indicated that more organic fertilizer should be applied to the soil in these vineyards. Optimized fertilization based on soil nutrient levels plays an essential role in sustaining production resources, increasing economic benefits and improving environmental conditions of vineyards.
