| 摘 要： | 对四川省凉山州8个主要植烟县(市)231个土壤样品的养分指标进行了测定,并运用偏相关分析确定了各土壤养分指标的权重,通过估算土壤肥力综合指标值(IFI)对凉山植烟区土壤肥力进行了综合评价。结果表明:(1)凉山烟区土壤中有机质、全钾和有效钾含量丰富,全氮、碱解氮以及土壤有效硫含量过高,全磷、速效磷和水溶性氯含量偏低,土壤pH值较为适宜;(2)根据IFI大小将全区土壤肥力分为高、较高、中等、较低和低5个等级,土壤养分处于中等、较高和高水平占全区所有土壤样品比例的75.36%;其中冕宁和普格的IFI平均值较高,会理的IFI平均值较低,其余地区IFI平均值居中。 |

| Abstract: | Selecting 231 soil samples from 8 main tobacco-growing counties（cities） in Liangshan state of Sichuan province as the tested materials,their nutrient index was analyzed,and the method of partial correlation analysis was applied to determine the weighted value of each soil nutrient index,and the soil fertility in Liangshan tobacco growing area was comprehensively evaluated by estimating integrated fertility index（IFI）.The results showed that：（1） The contents of organic matter,total K and available K were rich,contents of total N,alkali-hydro N and available S were high,contents of available P,total P and water soluble Cl were low,and the pH value was suitable in Liangshan tobacco-growing soils.（2） According to IFI values,soil fertility of the whole Liangshan tobacco-growing area could be classified into five grades： higher,high,medium,low and lower,and the proportion of soil fertility grades above medium was 75.36%,the average IFI values of Mianning and Puge were higher,that of Huili was lower,and those of the other counties were medium. |
