为了对施甸植烟土壤养分进行分析与综合评价，该文利用SPSS软件对72个土壤样品的9项理化指标进行统计分析。结果表明，土壤肥力最高的10个样本（占总样本的13.89%），综合得分F∈[0.5658，1.9826]；土壤肥力较高的25个样本（占总样本的34.72%），综合得分F∈[0.0053，0.4738]；土壤肥力较低的24个样本（占总样本的33.33%），综合得分F∈[-0.4985，-0.0445]；土壤肥力最低的13个样本（占总样本的18.06%），综合得分F∈[-0.8842，-0.5174]。因此，鉴于全县植烟土壤肥力存在着较大差异，对土壤肥力较高的田地，要施用适量有机肥和复合肥；而土壤肥力处于较低水平的，则要足量、配合施用有机肥和复合肥。

The contents of 9 components in 72 soil samples were analyzed and evaluated by the method of factor and system cluster with SPSS softwate in this paper,in order to evaluate the soil fertility in Shidian tobacco-growing areas. The results showed that the soil fertility of ten samples(13.89% of the total)was the highest with comprehensive scores from 0.565 8 to 1.982 6;thirty-two samples(34.72% of the total) was the second with comprehensive scores from 0.005 3 to 0.473 8;twenty-three samples(33.33% of the to-tal)was the third with comprehensive scores from -0.498 5 to -0.044 5;fourteen samples(18.06% of the to-tal)was the lowest with comprehensive scores from -0.884 2 to -0.517 4. Therefore,in view of great differ-ence in soil fertility through Shidian tobacco-growing areas,the right amount of organic fertilizer and com-pound fertilizer are applied to the fields of high soil fertility,and plenty of organic fertilizer and compound fertilizer are used for the fields of low soil fertility.
