摘　　要：为了解云南省昭鲁坝区植烟土壤有效锌含量分布情况,对昭鲁坝区9个乡镇324个土样进行分析。结果表明,昭鲁坝区植烟土壤有效锌含量适宜范围样本占17.28%,79.01%样本高于适宜范围,3.70%的样本低于适宜范围。植烟土壤有效锌含量随土壤pH值、有机质、年限的增加而增加,其中与pH值的增加呈极显著正相关,与有机质的增加呈显著相关。In order to know the content distribution of available zinc in tobacco-growing soil in Zhaoyang and Ludian area,324 soil samples from 9 towns were analyzed. The results were as follows. The available zinc content of 17. 28% soil samples was in the optimal range,that of 79. 01% samples was above the optimal range,and that of 3. 71% samples was lower than the optimal range. The content of available zinc increased with the rising of pH value,organic matter content and tobacco-growing age,which had extremely significant correlation with pH value,and had significant correlation with organic matter content.
