| 摘 要： | 为了解湖南烟区土壤有效态微量元素的空间分布规律,采集了3 295个土样并利用多元统计与地统计学方法对其有效态微量元素进行了研究.结果表明:湖南烟区土壤有效钼含量较低,有效锌含量适宜,有效铜、有效锰、有效铁含量丰富.有效锌、有效铜、有效铁含量表现为湘南、湘中较高,湘西较低;有效钼、有效锰则是由东往西增加.施肥时应适当增施钼肥,并注意钼肥形态,湘西地区还应适当增施锌肥. |

| Abstract: | In order to understand the spatial distribution of soil microelements in Hunan tobacco-growing areas,the 3 295 soil samples were collected and content of its microelements were studied by multivariate statistics and geostatistics. Results showed that contents of available Mo in the soils was lower;contents of available Zn was adequate;available Cu,available Mn and available Fe contents were rich. Available Zn,available Cu and available Fe contents show as higher in Xiangnan area and Xiangzhong area while lo... |
