Then the reasons of fuel-tobacco continuous cropping was reviewed with regards to soil nutrient unbalance, soil physical properties, autotoxicity of roots exudates, decrease of beneficial microorganisms, increase of harmful microorganisms. Last, the controlling measures of continuous cropping were reviewed, that was balanced fertilization, organic fertilization, deep plowing, rational crop rotation, rational intercropping and biological control.
