Advances in Acidification and Improvement of Tobacco Planting Soil

The soil acidification not only interferes with tobacco growth and development, but also retards the formation of quality tobacco leaves. At present, the problem of soil acidification in tobacco planting regions in Southern China is severe. In view of this, we summarizes the causes of soil acidification, the mechanism of soil acidification, and risk of soil acidification on tobacco growth and development, yield and quality. Improvement technique on soil acidification is also proposed in this paper.
