重庆市烤烟质量空间变异特征及其与作物茬口关系研究

Study on Spatial Variance Characteristics of Chongqing Tobacco Leaf Quality and Its Relationship with Previous Crop

对重庆市2009年所有产烟区的单料烟以及不同作物茬口烤后烟进行全面评吸评价。结果表明,对于上部叶(B2F)来说,以武隆、彭水、奉节和丰都的综合品质较好,其中武隆最好,南川最差;对于中部叶(C3F)来说,以秀山、奉节、酉阳和武隆的综合品质较好,而涪陵、万州和黔江较差;对于下部叶(X2F)来说,秀山、丰都、彭水和武隆的综合品质较好,而巫溪和万州较差。前茬作物类型对烤后烟质量评吸评价结果具有不同的影响,其中,以绿肥前茬烤后烟的综合品质指标和特征指标最好,烟叶和水稻前茬次之,而以玉米前茬最差。

The author made a comprehensive smoking evaluation on flue-cured tobacco with different previous crops in all tobacco-planting areas of Chongqing city in 2009.The results indicated that the comprehensive quality of upper tobacco leaf（B2F） in Wulong was the best,that in Pengshui,Fengjie and Fengdu county was better,and that in Nanchuan was the worst.The better comprehensive quality of middle tobacco leaf（C3F） appeared in Xiushan,Fengjie,Youyang and Wulong county,and the worse tobacco leaf quality of C3F occurred in Fuling,Wanzhou and Qianjiang county.As for lower tobacco leaf（X2F）,the better comprehensive quality was found in Xiushan,Fengdu,Pengshui and Wulong county,and the worse tobacco leaf quality occurred in Wuxi and Wanzhou county.The type of previous crop had different effects on the smoking quality of flue-cured tobacco,and the flue-cured tobacco whose previous crop was green manure had the best leaf comprehensive quality indexes and characteristic indexes,which was followed by the flue-cured tobacco with previous crop tobacco,rice and maize,respectively.
