Abstract:

Precision through field experiments, on the bio-organic fertilizer and straw cover used in combination to enhance the capacity of the soil nutrient supply and quality of flue-cured tobacco has done research. The experimental results show that: Increasing bio-organic fertilizer can significantly increase the capacity of the soil nutrient supply, flue-cured tobacco leaves in the elevated potassium and lower in leaf nitrogen content, nicotine content and chlorine ion content and other harmful factors, significant improvements in tobacco quality.
