摘　　要：明确广元市汉阳镇植烟土壤肥力状况,为该区烟草种植合理布局、平衡施肥和土壤保育提供数据支撑。以广元市汉阳镇植烟土壤为研究对象,采集25个土样,测定土壤pH、基础养分和矿质营养,利用模糊数学综合评价法计算土壤综合肥力得分(IFI)。结果表明,该烟区土壤pH、有机质和全氮平均值分别为6.98、19.13 g/kg和1.48 g/kg,均处于中等水平,其中72.00%土壤有机质含量高于15.00 g/kg;土壤有效磷、碱解氮和速效钾平均含量分别为30.41、46.79和135.72 mg/kg, 56%的土壤有效磷含量低于10 mg/kg, 68%土壤速效钾含量低于150 mg/kg, 52%土壤IFI处于低水平。该烟区土壤Ca、Fe、Mn、P变异系数分别为39.94%、50.02%、65.79%、49.70%,均属于强变异;土壤Mg、Cu、Zn变异系数分别为31.30%、31.66%、32.71%,均属于中等变异,各指标变异系数表现为Mn>P>Ca>Zn>Cu>Mg>K。该烟区土壤各矿质元素之间大多呈显著或极显著相关,各理化指标间大多呈显著或极显著相关,各矿质元素与基础养分间相关性较差。To clarify the soil fertility status of tobacco planting in Hanyang Town,Guangyuan City,and provide data support for rational distribution of tobacco planting,balanced fertilization and soil conservation.In this study,25 soil samples were collected from tobacco planting soil in Hanyang Town,Guangyuan City.The soil pH,basic nutrients and mineral nutrients were measured,and the soil comprehensive fertility score(IFI)was calculated by fuzzy comprehensive evaluation method.The results showed as follows:the average values of soil pH,organic matter and total nitrogen were 6.98,19.13 g/kg and 1.48 g/kg,respectively,which were in the middle level,and 72.00%soil organic matter content was higher than 15.00 g/kg.The average contents of soil available P,alkali-hydrolyzable N and available K were 30.41,46.79 and 135.72 mg/kg,respectively.The available P of 56%soil was lower than 10 mg/kg,the available K of 68%soil was lower than 150 mg/kg,and the IFI of 52%soil was at low level.The variation coefficients of soil Ca,Fe,Mn and P were 39.94%,50.02%,65.79%and 49.70%,respectively.The variation coefficients of soil Mg,Cu and Zn were 31.30%,31.66%and 32.71%,respectively,belonging to moderate variation.The variation coefficients of each index showed as Mn>P>Ca>Zn>Cu>Mg>K.There were significant or extremely significant correlations between most of the soil mineral elements and most of the physical and chemical indexes,but the significance between the mineral elements and the basic nutrients was poor.
