6个烤烟品种在保山怒江流域生态适应性研究

Ecological Adaptability of Six Tobacco Varieties in Baoshan Nujiang River Basin

[目的]比较6个烤烟品种在云南省保山怒江流域的生态适应性，为该地区烤烟品种的更新换代和区域化布局提供依据。[方法]在保山市龙陵县进行了T29、T64、T66、云烟99、K346与对照云烟87的区域试验，调查6个品种的主要生育时期、农艺性状、植物学性状、抗病性、原烟外观质量、经济性状。[结果]在6个供试品种中，各品种的大田生育期在139—143d；从农艺性状上看，T66表现较好；从植物性状上看，云烟99和K346比其他几个品种要好；K346抗病性较强；从原烟外观质量上看，6个品种差异不明显；从经济性状上看，云烟99的产值最高。[结论]综合6个烤烟品种的生态适应性研究结果可知，云烟99各方面性状表现好，适合在云南省保山市怒江流域推广种植。

[ Objective] To compare the ecological adaptability of six tobacco varieties in Baoshan Nujiang River Basra of Y unnan Provmce,and to provide references for the upgrading and regional layout of tobacco variety in this region. [ Method] Regional experiments about T29 ,T64 ,T66, yunyan99, K346 and yunyan87 were carried out in Longling County of Yunnan Province. We detected the growth time ,agronomic characters, disease resistance,appearance quality of tobacco leaves and the economic characters. [ Result ] Among the six tested varieties,growth period was 139 - 143 d. As for the agronomic characters,T66 was better than others. K346 and Yunyan 99 were better than other varieties in plant traits. K346 showed the best disease resistance. There were no significant differences in the appearances quality of tobacco leaves. In economic characters Yunyah99 had the highest output value. [ Conclusion] Adaptability test of the these six varieties showes that Yunyan99 has better comprehensive characters,which is suitable to be cultivated in Baoshan Nujiang River Basin of Yunnan Province.
