摘要：

为充分摸清南平烟区植烟土壤微量元素丰缺状况及其演变趋势，科学指导烟区平衡施肥。利用南平市植烟土壤普查资料，分析了土壤铁、锰、铜、锌、硼、氯养分状况与演变趋势，结果表明：土壤有效铁、锰、铜、锌、硼及水溶性氯含量分别为(88.49±62.66) mg/kg、(26.11±19.08) mg/kg、(3.15±2.01) mg/kg、(2.55±1.42) mg/kg、(0.26±0.19) mg/kg、(20.22±17.22) mg/kg；各养分变异系数均超过50%，属强变异。从各养分演变趋势分析，随着种烟年限增加，土壤供铁、锰能力均呈增加趋势，而供铜、锌、硼、氯能力则呈降低趋势；从土壤保育和优质烟叶生产角度，应重视铁、锰营养过剩及铜、锌、硼、氯营养的补给。

Abstract:

In order to fully find out the Nanping tobacco soil microelements and its evolution trend, scientific guidance tobacco balanced fertilization. Using Nanping plant smoke soil census data, analyzed the soil iron, manganese, copper, zinc, boron, chlorine nutrient status and evolution tendency, the result showed: the contents of Nanping plant smoke soil effective iron, copper, manganese and effective zinc, effective boron, water-soluble chlorine averaged (88.49±62.66) mg/kg, (26.11±19.08) mg/kg, (3.15±2.01) mg/kg, (2.55±1.42) mg/kg, (0.26±0.19) mg/kg, (20.22±17.22) mg/kg respectively. Various nutrients variation coefficient were more than 50%, belong to strong mutation. From the nutrient evolution tendency analysis, along with the kind of smoke fixed number of year for increased, soil of iron and manganese ability were tending to increased, and for copper, zinc, boron, chlorine ability was a trend to decrease. From the angle of soil conservation and high-quality tobacco production, we should attach importance to iron and manganese nutrition surplus and copper, zinc, boron, chlorine nutrition supply.
