摘要
为了探讨低纬度高海拔地区海拔高度与烟叶品质的关系，在黔西南州内５个县（市）纬度相近、海拔不同地区进行了３年（１９９１～１９９３）试验。试验结果表明，在黔西南州内，随着海拔的增高，烤烟的大田生育期和成熟期逐渐延长，亩产量、亩产值以及上等烟比例亦有上升趋势，烟叶的外观质量和内在品质也相应提高，尤其在海拔１４６０～１７００ｍ地区烟叶产量高品质好，最适宜优质烟叶的生长。该研究对指导我省烤烟生产的合理布局与因地制宜地提高烟叶品质有现实的意义。
In order to understand the relationship between tobacco quality and elevation height,a series of field experiments were conducted in five places with similar latitude and different elevation in five counties of QianXinan prefecture in 1991-1993.The results showed that following the rise of the elevation,the growth duration and maturity date of tobacco delayed gradually,yield and product value per mu and the percentage of high quality tobacco levels also showed an increasing tendency.In higher elevation areas,both inside and outside marketable value of the tobacco leaves were improved correspondingly,especially in areas with elevation of 1460-1700m,which suit for the cultivation of high quality tobacco.This study could contribute to rational distribution of tobacco production Guizhou province and improve the quality of tobacco leaves in the light of local conditions.
