摘　　要：2005年采集了福建省3个主产烟区有代表性的植烟土壤样品557个,并进行了土壤中、微量元素分析。结果表明,该区植烟土壤平均交换性钙含量(1059.3±395.3)mg/kg、交换性镁(171.2±125.3)mg/kg、有效硫(34.1±21.7)mg/kg、水溶性硼(0.18±0.14)mg/kg、水溶性氯(23.5±11.8)mg/kg、有效锌(1.99±1.30)mg/kg、有效铜(2.84±1.56)mg/kg、有效铁(216.6±98.2)mg/kg。有27.6%的土壤缺钙,有12.4%的土壤严重缺镁,有42.2%的土壤缺硫或潜在缺硫,土壤普遍缺B,土壤水溶性Cl含量在比较适宜范围,土壤Cu、Fe、Zn养分较丰富。为此,烤烟生产上要因地制宜,注意增施钙镁磷肥或氧化镁,喷施硼肥。The middle-microelements nutrients in 557 soil samples collected from 3 regions of tobacco-growing areas in Fujian provinces were analyzed. The results showed that the average content of exchangeable Ca, exchangeable Mg, available sulfur, water-soluble B, water-soluble Cl, available Zn, Cu, Fe were （1059.3±395.3）mg/kg, （171.2±125.3）mg/kg, （34.1±21.7）mg/kg, （0.18±0.14）mg/kg, （23.5±11.8）mg/kg, （1.99±1.30）mg/kg, （2.84±1.56）mg/kg, （216.6±98.2）mg/kg, respectively. 27.6% of soil in tobacco-growing areas were short of Ca, 12.4% of soil in tobacco-growing areas were short of Mg, and Calcium magnesium phosphate fertilizer or MgO should be applied. 42.2% of soil in tobacco-growing areas were short of S, the water-soluble B of soil in tobacco-growing areas was deficiency in general, the water-soluble Cl of soil in tobacco-growing areas was suitable for tobacco growth, available Cu, Fe, Zn of soil in tobacco-growing areas was enrichment. The fertilization suggestion of spraying B was recommended.
