摘要
为探索烤烟与芳香植物间作对烟株生长发育及产质量的作用效果,采用大田试验开展烤烟与百合、菊花、香茅和紫茉莉的间作研究.结果表明,烤烟间作芳香植物对烤烟的株高、茎围、节距的影响并不明显,但不同部位的叶面积有一定程度的减小.烤烟间作百合、菊花能提高中部叶烤烟烟碱和钾含量,同时降低糖含量,上部叶和中部叶的氮碱比和糖碱比更接近优质烟叶的标准范围.烤烟与芳香植物间作主要对烟叶香气质、刺激性和劲头产生显著影响,其中,以烤烟间作百合、烤烟间作香茅对烤烟感官质量的改善最为明显.烤烟间作百合对烤烟产量、产值、均价、上等烟比例和中部叶比例的提升最为显著.综合而言,烤烟间作百合对烟株生长发育和烤后烟叶产质量提升作用最显著.
Abstract
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.
