摘　　要：土壤作为供给烟株微量元素的主要来源,进行植烟土壤微量元素丰缺程度及其影响因素的研究对于烤烟生产尤为重要。通过分析福建省烟区2005年及2018年2次植烟土壤普查数据,利用地统计学方法,对福建省植烟土壤微量元素(铁、锰、铜、锌)养分时空变异特征及其驱动因素进行研究。本研究表明:2005-2018年的14年间,土壤微量元素含量虽有一定的上下浮动,但均处于“丰富”或“极丰”水平。进一步研究后发现,2018年福建省植烟土壤有效铁含量主要集中在200~350 mg/kg区间(83.90%),受非结构性因素的影响逐渐增强;有效锰含量主要集中在10~25 mg/kg区间(90.14%),仍主要受结构性因素影响;有效铜含量主要集中在1.5~3 mg/kg区间(80.44%),受结构性因素和非结构性因素共同影响;有效锌含量主要集中在1.5~4 mg/kg区间(91.88%),空间自相关性与土壤有效铜相似。相关分析和逐步回归分析结果显示,土壤pH与有机质与土壤微量元素含量直接相关,而土壤交换性镁则通过对pH的影响与微量元素间接相关。福建省烟区基本不存在铁、锰、铜、锌等微量元素缺乏土壤,整体含量偏高。在福建省土壤偏酸性背景下可采取以氢氧化镁、氧化镁、钙镁磷肥替代硫酸镁肥的措施对于土壤微量元素进行一定的调控。Soil serves as the primary repository of trace elements required for tobacco growth,making it crucial to investigate the plentiful-lack index and the factors influencing the abundance of these trace-elements in soil used for tobacco cultivation.Therefore,this study utilized the findings from two soil surveys conducted in 2005 and 2018 within Fujian Province’s tobacco-planting soil,employing geostatistical analysis methods to examine the spatial and temporal variability characteristics and the driving factors affecting the trace elements(Fe,Mn,Cu,Zn).The study revealed that over the 14 years period from 2005 to 2018,there was a noticeable fluctuation in the trace element content of soil,yet all remained at either high or extremely high levels.Upon further analysis,it was found that the available iron content in Fujian Province’s tobacco-planting soil in 2018 predominantly ranged from 200-350 mg/kg(83.90%),with distribution mainly influenced by non-structural factors;the available manganese content predominantly fell within the range of 10-25 mg/kg(90.14%),primarily influenced by structural factors;the available copper content was primarily concentrated in the range of 1.5-3 mg/kg(80.44%),influenced by a combination of structural and non-structural factors;the available zinc content predominantly ranged from 1.5-4 mg/kg(91.88%),exhibiting a spatial auto-correlation pattern similar to that of the soil available copper;correlation and stepwise regression analyses revealed that soil pH and organic matter directly influenced the content of soil trace elements,whereas soil exchangeable magnesium had an indirect effect on these elements through its impact on pH.In the tobacco-planting regions of Fujian Province,trace-element deficiency such as Fe,Mn,Cu,Zn was essentially non-existent,with overall contents being high.Amidst the acidic soil conditions prevalent in Fujian Province,fertilizers such as magnesium hydroxide,magnesium oxide,and calcium magnesium phosphate could be utilized as alternatives to magnesium sulfat
