Abstract：In order to know the content distribution of available zinc in tobacco-growing soil in Zhaoyang and Ludian area,324 soil sanples 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.
