Abstract
In order to investigate the contents and distribution of microelement in the soil of Sichuan tobacco growing areas, the contents of effective microelement in 298 soil samples were tested and evaluated. The results showed that the contents of effective Fe and Mn were very plentiful, effective Cu was rich, effective B was extremely deficient, and most of Sichuan soil was lack in effective Zn. The recommended fertilizing suggestion was that B should be applied in all tobacco growing areas of Sichuan Province, Zn should be applied in the north-east areas, and lime should be applied in the soil that was rich in Fe and Mn and pH value was lower than 5.5.
