摘　　要：通过对衡阳同一品种同一烟区随机抽取的16份不同产量的烟叶进行化学成分分析,研究了产量与烟叶化学品质的关系。结果表明,上、中、下三个部位的化学成分经过量化后的品质总得分与烟叶产量呈极显著相关(r=0.796 4**),产量在2 040 kg/hm2～2 775 kg/hm2时烟叶品质得分随着产量的上升而增加,产量超过2 775 kg/hm2时烟叶品质得分开始下降,且下降幅度大,品质变差。The relationship between the yield and the chemistry, quality of leaf tobacco was studied by the analysis on chemical composition of 16 different yield of leaf tobacco that draw at random in the same variety and same smoke area in Hengyang. The result indicated that the total score, which quantification by the upper, middle and lower spot chemical composition, obviously related to the yield of tobacco leaf （r=0.7964 ＊＊）. When the yield of the tobacco leaf keep in 2 040 kg/hm^2-2 775 kg/hm^2, the quality of the tobacco leaf total score increased along with the yield rise. And the quality total score dropped quickly when the yield surpassed 2 775 kg/hm^2, and the quality varied.
