云南保山高海拔地区不同烤烟品种适宜性分析

为了研究掌握云南保山高海拔烟区不同烤烟品种适宜性问题,2011—2012年对云南保山烟区2000 m海拔区域7个烤烟品种共计99个C3F烟叶样品分析,结果表明：‘云烟’系列品种整体海拔敏感度低,其中‘云烟100’综合表现最好,烤后烟叶外观物理特性突出,内在化学成分协调,各指标均在云南优质烤烟适宜范围内,工业可用性较高,适宜在保山烟区高海拔区域种植;而‘云烟99’原烟含梗率偏高,‘云烟97’总糖含量偏高,‘K326’烟碱和总氮含量偏高且总糖含量偏低,以上3个品种烤后烟叶内在化学成分不协调,海拔敏感度高,工业可用性较低,不适宜在保山烟区高海拔区域种植;‘云烟85’、‘云烟87’、‘红花大金元’3个品种在保山烟区高海拔区域种植适宜性有待进一步分析验证。

Study on Suitability of Different Flue-cured Tobacco Varieties in Baoshan, Yunnan High Altitude Region

In order to study the suitability of different flue-cured tobacco varieties in Baoshan,Yunnan high altitude region,used 99 flue-cured tobacco middle leaves of grade C3F about 7 different varieties from Baoshan,Yunnan 2000 m altitude region through 2011-2012 collected were analyzed.‘Yunyan＇series varieties overall elevation sensitivity was low,‘Yunyan 100＇integrated performance were best,leaf appearance outstanding physical properties,intrinsic chemical composition,all the indicators were in high quality flue-cured tobacco of yunnan suitable range,industrial high availability,suitable planting in Baoshan high altitude area;‘Yunyan 99＇stem content on the high side,‘Yunyan 97＇total sugar content was on the high side,‘K326＇high nicotine and total nitrogen content and total sugar content was low,all above three varieties after baking tobacco intrinsic chemical composition inharmonious,high altitude sensitivity,industrial availability was low,not suitable for planting in Baoshan high altitude area;‘Yunyan 85＇,‘Yunyan 87＇,‘Hongda＇whether suitability plant in Baoshan high altitude area analysis needed further validation.
