摘　　要：以南宁市石埠镇周边某葡萄观光采摘园为调查对象,采集该园有代表性的土壤样本和葡萄叶片样本,并对其营养状况进行分析。结果表明,该葡萄园土壤p H值在4.6~5.5之间,呈强酸性;土壤有机质平均含量为21.44 g/kg,采样区的土壤全磷含量均在1.0 g/kg以上,土壤水解性氮、有效磷、速效钾含量较高,全钾和全氮含量以及土壤Ca、Mg、Zn、B含量远远低于平均值;土壤氯离子含量仅为0.13~0.22 g/kg,属于较缺乏的状态;土壤阳离子交换量在8.61~16.94 cmol(+)/kg之间,与土壤呈强酸性有很大关系。葡萄叶片氮、磷、钾、钙含量分布范围分别为1.82%~2.41%、0.19%~0.23%、1.77%~2.54%和1.04%~1.70%,营养水平处于适当范围内;叶片镁含量最高值仅为0.19%,硼含量最高值仅为21.69 mg/kg,叶片镁和硼元素营养水平严重低于标准范围;叶片锌含量最低值达97.0 mg/kg,营养水平较高。南方酸性土壤导致葡萄园普遍缺乏镁、硼等微量元素,应根据葡萄营养需求合理施肥,适当减少大量元素肥料的施用,有针对性地补充镁肥和硼肥。Took the soil and leaf samples from one sightseeing vineyard located in Shibu area of Nanning City as test materials,nutrition of these samples were analyzed in this paper.The results showed that the soil p H was between 4.6-5.5,showed highly acidic.The average content of soil organic matter was 21.44 g/kg.The total phosphorus content was over 1.0 g/kg.The content of soil hydrolysis nitrogen,available phosphorus and available potassium was higher than the standard.The contents of total potassium,nitrogen and soil Ca,Mg,Zn,B were all below the average,and the differences in each sampling area were not significant.The content of soil chloride ion was only 0.13 -0.22 g/kg,which was relatively deficient.The soil cation exchange capacity was between 8.61-16.94 cmol（＋）/kg,which was strongly related to the strong acidity of soil.The contents of nitrogen,phosphorus,potassium and calcium in grape leaves were between 1.82%-2.41%,0.19%-0.23%,1.77%-2.54% and 1.04%-1.70%,and the nutritional level was in the appropriate range.The maximum content of magnesium in leaves was only 0.19%,and the maximum boron content was only 21.69 mg/kg,while the nutrient levels of magnesium and boron in leaves were significantly lower than the standard.The minimum zinc content in leaves was 97.0 mg/kg,and the nutrient level was higher.Southern acidic soil in vineyard led to the lack of magnesium,boron and other trace elements generally,farmers should appropriate to reduce the amount of macroelement fertilizer,supplement magnesium and boron fertilizer according to the nutrition needs of grape.
