摘　　要：为了解重庆市武隆县植烟土壤微量元素状况,运用GPS定位,采集武隆县植烟土壤耕层312个土壤样品并进行了分析。结果表明,武隆县土壤有效态微量元素含量差异较大,铁、锰含量非常高,在养分为很高的等级中分别占96.15%和96.47%,二者养分不同等级所占百分比也基本相似,而铜则主要集中在养分为高的等级,锌则主要集中在养分为中的等级,少数地区可能缺锌。有效态微量元素在不同地域上的分布差异也很大,有效铁在中西部、有效锰在中南部、有效铜在中部和西北部、有效锌在中部小范围内含量较高。其他地区的4种元素分布基本上能够满足植烟区营养需要。In order to investigate the available micronutrient status in tobacco-growing soil in Wulong, Chongqing, we took soil samples before the tobacco was transplanted and fertilized by using GPS. This article takes tobacco-growing soils of Wulong in Chongqing for research object, which references nutrition status of available trace element and combines with GIS plot, analyzes and compares the distribution of Wulong＇s trace element about tobacco-growing soil. The results of the study show that the available trace element has a big difference in content. According to all the nutrient levels percentage, the available iron and manganese have a high content, which in nutrition for high level reaching to 96.15% and 96.47% respectively. The content of available copper is high. The available zinc content is medium. The distribution of available trace element has a big variance in different regions in Wulong. In the west including Songrning, Miaoya, Yajiang and Qingmu and Mugen town in the north, the available iron has a high content. The available manganese, copper and zinc all have a high content nearby the Yangja wells. These regions are expected to take imorovement measures in order to prevent the tobacco poisoning, by overabundance content of trace elements.
