Objective] The aim was to find out an effective intercropping method to control heavy metal content of flue-cured tobacco.[Meth-od] By using different intercropping methods, biological characteristics during flue-cured tobacco growth period and heavy metal content in soil and tobacco after harvest were investigated.[Result] Different intercropping treatments had promoting effects on tobacco growth, intercropping green beans had more obvious effect.At the same time of ensuring tobacco plant growth, effects of intercropping treatments on heavy metal con-tent in soil and tobacco leaf had significant differences.[ Conclusion] Proper intercropping in production has a certain practical significance on flue-cured tobacco growth and heavy metal content reduction.
