Effects of Intercropping of Flue-cured Tobacco and Aromatic Plants on Growth,Development,Yield and Quality of Tobacco Plants
In order to explore the effect of intercropping of flue-cured tobacco and aromatic plants on the growth,development,yield and quality of flue-cured tobacco,field experiments were carried out to study the intercropping of flue-cured tobacco with lily,chrysanthemum,citronella and purple jasmine.The results showed that the effect of aromatic plant intercropping on plant height,stem circumference and pitch of flue-cured tobacco was not obvious,but the leaf area of different parts of flue-cured tobacco decreased to a certain extent.Intercropping with lily and chrysanthemum could increase nicotine and potassium content of flue-cured tobacco in middle leaf,and reduce sugar content at the same time.Nitrogen-alkali ratio and sugar-alkali ratio of upper and middle leaves were closer to the standard range of high quality tobacco leaves.The intercropping of flue-cured tobacco and aromatic plants mainly had significant effects on the aroma quality,irritation and strength of flue-cured tobacco,among which the treatment of lily and citronella intercropped with flue-cured tobacco had the most significant improvement on the sensory quality of flue-cured tobacco.Flue-cured tobacco intercropping with lily had the most significant effect on flue-cured tobacco yield,output value,average price,the proportion of high-grade tobacco and the proportion of middle leaves.In general,the intercropping of flue-cured tobacco with lily has the best effect on the growth,development,yield and quality of flue-cured tobacco.
