摘　　要：研究了不同种植密对白肋烟烟叶常规化学成分和烟叶品质的影响,结果表明:种植密度对白肋烟的常规化学成分的影响很大,随着种植密度的增加,总氮和烟碱总体上呈下降趋势,还原糖呈增加的趋势,K含量先增后降,淀粉和Cl的含量变化不明显,适宜种植密度为19995～20835株/hm2。The impacts of 9 different planting densities on the conventional chemical compositions and quality of leaves of burley tobacco were studied.The results showed that different planting densities had a great impact on the conventional chemical compositions in the leaves of burley tobacco.Along with the increase of planting density,the contents of total nitrogen and nicotine basically showed a decreasing trend,reducing sugar content had a slight increasing trend,potassium content increased firstly and then dec...
