摘　　要：【目的】了解植烟土壤pH与有机质对海拔和土壤类型的响应。【方法】采用统计学方法分析了弥勒市10个乡(镇)的251个土壤样品的pH和有机质与海拔、土壤类型的关系,及土壤pH与有机质的相关关系。【结果】弥勒市植烟土壤pH值变幅为4.39~8.45,均值为6.51,56.57%的植烟土壤pH处于适宜范围(pH值5.0~7.0)内,土壤pH水稻土>胶泥土>红壤>砂壤土,而有机质含量受土壤类型的影响不显著(P>0.05);土壤有机质平均值为30.60 g/kg,变幅为5.02~64.28 g/kg,全市41.40%的土壤有机质处于中等水平,59.80%的土壤有机质含量处于高及丰富水平,不同土壤类型间有机质高低顺序:砂壤土>红壤>胶泥土>水稻土;该烟区海拔介于1135~2124 m,植烟土壤pH值随海拔升高呈现"M"型变化趋势,而有机质则呈现"W"型变化趋势;植烟土壤pH与有机质呈负相关关系。【结论】弥勒市多数地区的植烟土壤pH适宜,有机质含量较高,适宜烟草种植。【Objective】 The objective of this study was to understand the response of tobacco-planting soil pH and soil organic matter to altitude and soil type. 【Method】 Statistical analysis was used to study the relationship between soil pH and soil organic matter of 251 soil samples which selected from 10 towns and villages in Mile city, and the relationship between altitude, soil type, and soil pH, soil organic matter were analyzed. 【Result】the soil pH at tobacco-planting field in Mile city ranged from 4.39 to 8.45, and the average value was 6.51. The range of pH suitable for tobacco growth was 5.0-7.0, which accounted for 56.67 % of soil samples. The pH value in paddy soil was significantly higher than that of clay soil, followed by red soil and sandy loam soil. The average value of soil organic matter was 30.60 g/kg, and the amplitude of variation was from 5.02 to 64.28 g/kg. Of 41.40 % soil organic matter was moderate, while 59.80 % was abundant. However, the content of soil organic matter was not significantly affected by soil types(P>0.05), and showed sandy loam soil > red soil > clay soil > paddy soil. The elevation range of Mile tobacco area was from 1135 m to 2124 m, and the soil pH presented a trend of ‘M’ type with the increasing elevation, while the soil organic matter presented a trend of ‘W’ type. There was a negative correlation between soil pH and soil organic matter. 【Conclusion】In most areas of Mile city, the soil pH was suitable, and the content of organic matter was high, which was suitable for tobacco planting.
