摘要: [目的]为了探讨昆明烟区适宜的烤烟栽培措施,[方法]采用田间小区试验,研究了不同种植密度对烤烟常规化学成分、中性致香物质及经济性状的影响。[结果]结果表明:随着种植密度的增加,烟叶中总糖、还原糖及钾含量呈先升后降趋势,烟碱和氯离子含量呈先降后升趋势,而总氮含量则呈上升趋势;烟叶棕色化反应产物、类胡萝卜素降解产物、苯丙氨酸降解产物、西柏烷类降解产物和叶绿素降解产物及中性致香物质总量均随着种植密度增加先升后降,且均以T2处理含量最高;各处理烟叶经济性状以T2(120cm×60cm)最佳。[结论]因此,在昆明烟区,针对云烟87烤烟品种,120cm×60cm是较适宜的种植方式,可进行推广应用。

Abstract: To explore appropriate cultivation measures of flue- cured tobacco in Kunming, the effects of planting density on neutral aroma components, chemical components and economic characters were studied with field experiments. The results showed that, with the increase of planting density, the contents of total sugar, reducing sugar and potassium increased first and decreased later, contrary to the content change of nicotine and chlorine, and the content of total nitrogen increased. The contents of maillard reaction productions, carotenoid degradation productions, phenylalanine degradation products, cembranoids degradation products, chlorophyll degradation products and neutral aroma components in tobacco leaves were the highest in treatment T2(120 cm× 60 cm), and all showed a first increase and then decrease tendency with the increase of planting density. The economic characters of T2 had the best performance. Therefore, the planting density of 120 cm×60 cm is more appropriate for‘Yunyan87’in Kunming, and could be popularized and applied.
