植烟土壤酸化及改良技术研究进展

Advances in Acidification and Improvement of Tobacco Planting Soil

摘要: 土壤酸化不利于烟草生长发育,影响优质烟叶的形成。目前我国植烟土壤酸化问题严重,且主要集中在南部主要产烟区。鉴于此,笔者综述了引起土壤酸化的原因、土壤酸化的机理与危害,土壤酸化对烟草生长发育,产质量的影响以及改良土壤酸化的主要技术,并就土壤酸化改良技术提出了建议。

Abstract: 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.
