摘  要：
测定了湖南烟区1347个土壤样本的有效态微量元素含量,对其分布特点进行了评价。结果表明:(1)湖南烟区土壤有效锌含量较高,平均为2.24mgkg-1;有效锰含量丰富,平均为27.89mgkg-1;有效铜和有效铁含量极丰富,平均为3.28mgkg-1和81.30mgkg-1;水溶性氯含量适宜,平均为13.99mgkg-1;但有效硼和有效钼含量较低,分别有97.92%和56.35%的土壤样本含量在烤烟生长的临界值以下,均属缺乏状态。(2)湖南各烟区因有效态微量元素含量不同大致可分为4类,第Ⅰ类由桂阳独自成类;第Ⅱ类包括永州和浏阳;第Ⅲ类包括宁乡和怀化;第Ⅳ类包括常德、张家界、龙山和凤凰,并对各类的特点进行了描述。

摘  要：
The microelements contents in 1347 soil samples from Hunan tobacco-growing areas were determined, and their distribution was evaluated. The results indicated that: (1) Available Zn content in the soils was high in Hunan tobacco-growing areas with the mean of 2.24mg kg-1; available Mn content was rich with the mean of 27.89mg kg-1; available Cu and available Fe contents were very rich with the mean of 3.28mg kg-1 and 81.30mg kg-1, respectively; water soluble Cl content was medium with the mean of 13.99mg kg-1; but available B and available Mo contents were low and those in 97.92% and 56.35% soil samples were less than the critical value, respectively. (2) Based on the different contents of microelements and cluster analysis results, Hunan tobacco-growing areas could be divided into four groups: the first group was Guiyang; the second group included Yongzhou and Liuyang; the third group included Ningxiang and Huaihua; and the fourth group included Changde, Zhangjiajie, Longshan and Fenghuang..
