摘 要:目前,国内外对低纬度高海拔地区葡萄园的土壤肥力状况研究很少,本研究采集云南弥勒县酿酒葡萄原料基地10个生产核心区域的土壤样品,分析了pH值、CEC、有机质、氮、磷、钾等肥力指标,并采用Nemerow肥力综合指数法评价了该基地土壤的肥力特征。结果表明,弥勒县酿酒葡萄原料基地土壤酸碱性适宜,有机质缺乏,平均含量为0.72%;碱解氮含量偏低,平均值为67.81 mg/kg;速效磷、钾含量一般;全氮、磷、钾总体处于中等水平,但呈现养分区域不平衡现象。Nemerow肥力综合指数法评价结果显示,基地土壤肥力为Ⅱ级,即一般肥力水平。单项肥力指数全氮、碱解氮、有机质处于贫瘠水平,其他指标处于一般肥力水平或较高肥力水平。对此,可通过增施有机肥,测土配方施肥等措施进行针对性的施肥,提高弥勒县酿酒葡萄原料基地的土壤肥力。With little research about the soil fertility of the low latitude and high altitude vineyards all over the world at present, the soil sample data of ten core production region were collected form wine grape base in Mile County, Yunnan Province. It focused on the analysis of fertility indicators like pH ,CEC ,organic matter, nitrogen,phosphorus and potassium, and meanwhile the soil fertility characteristics in this base were evaluated based on the Nemerew fertility index. The results showed that the soil pH was suitable in wine grape base of Mile County but lacks of organic matter; nitrogen content was low with an average of 67.81 mg/kg;the content of available phosphorus and potassium was in the general; the total amount of nitrogen,phosphorus and potassium were at a medium level overall, showing a nutrient regional imbal- ances. According to the Nemerow fertility index, soil fertility in base was level II which was general. Soil individual fertility index of total nitrogen, available nitrogen and organic matter were in the barren level, at the same time, other indicators were in the general fertility level or higher fertility levels. As a result, we could improve the soil fertility of raw material base in Mile county wine grape from organic fertilizer and soil testing to conduct targeted fertilization.
