摘　　要：为了解临沧烟区植烟土壤养分状况,对临沧烟区41个土壤样品进行测试分析.结果表明：（1）82.9％土壤pH在4.5 ～5.5,平均值为5.27,镇康县pH偏弱碱性.（2）土壤氯离子、有效硼质量分数偏低,63.4％土壤氯离子小于10.0 mg/kg; 85.3％土壤有效硼小于1.0 mg/kg,部分地区严重缺硼.（3）有效氮、速效钾适中,65.9％的土壤有效氮大于110 mg/kg,61.0％的土壤速效钾大于150 mg/kg;有机质、交换性镁、有效锌质量分数较高,78.1％的土壤有机质大于25 g/kg,75.6％的土壤交换性镁大于100 mg/kg,80.5％的土壤有效锌大于0.5 mg/kg;速效磷质量分数丰富,92.7％的土壤速效磷大于10 mg/kg.（4）不同土壤类型和地区间土壤养分差异较大,其中黄壤土肥力低,有机质、有效氮、速效磷、有效硼、交换性钙、交换性镁、有效锌质量分数偏低;耿马县土壤速效钾、有效硼、交换性钙、交换性镁、有效锌质量分数偏低.总体来看,临沧烟区应适当施氯,普遍补充硼肥.In order to evaluate the main soil nutrient of tobacco-growing area of Lincang,soil samples from forty-one tobacco-growing area were analyzed.The results showed that：（1） Generally,Lincang tobacco-growing soil present acidic,about 82.9% of the soil pH value rage from 4.5 to 5.5,in addition to the soil of Zhenkang,which is weakly alkaline.（2） The contents of chloride and available boron are low,about 63.4% of the soil chloride content are less than 10 mg/kg,and about 85.3% of the soil available boron content are lower than 1.0 mg/kg,even the available boron content of the small number of the soil is severely deficient.（3） The contents of the soil available nitrogen and potassium are moderate.Up to 65.9% of the soil available nitrogen contents are highcr than 110 mg/kg,and about 61.0% of the soil available potassium contents were higher than 150 mg/kg.The contents of organic matter,exchangeable magnesium and available zinc are high.78.1% of the soil organic matter contents are higher than 25 g/kg; 75.6% of the soil exchangeable magnesium contents are higher than 100 mg/kg; 80.5% of the soil available zinc contents are higher than 0.5 mg/kg.92.7% of the soil available phosphorus contents are higher than 10 mg/kg.（4） The soil nutrient content are quite different,as the soil types and regions are different,especially the yellow soil,the fertility of which is low,and the content of organic matter,available nitrogen,available phosphorus,available boron,exchangeable calcium,available magnesium and available zinc are low.The content of soil available potassium,available boron,exchangeable calcium,exchangeable magnesium and available zinc of Gengma are lower than the standard contents.In general,Lincang tobacco-growing area should apply chlorine appropriately,and the boron is needed in general.
