适宜永胜烟区栽培的烤烟品种比较试验

Comparison Experiment of Flue-Cured Tobacco Varieties Suitable for Yongsheng Tobacco Area

为了筛选出适宜永胜烟区栽培的烤烟品种,选择云烟87、云烟97、云烟99和云烟121这4个品种进行田间品比试验。结果表明:从农艺性状来看,团棵期及旺长期以云烟99和云烟121田间表现较好,成熟期以云烟97田间表现最好;从抗病性来看,云烟99的抗病性最强,其次为云烟121;从烤烟化学成分含量来看,4个烤烟品种各等级烟叶的总氮含量偏低,总糖、还原糖含量均偏高,烟碱、氯、钾含量均适宜,其中以云烟99的烟叶化学成分含量最为适宜;从烤烟经济性状来看,云烟97的均价、产量、产值均最高,其次为云烟99,云烟121次之,云烟87表现最差。综合来看,云烟99更适宜在永胜烟区种植。

In order to screen out tobacco cultivars adaptive to Yongsheng tobacco-growing area,a field varietal comparison experiment was conducted between four tobacco varieties:Yunyan 87,Yunyan 97,Yunyan 99 and Yunyan 121.The results demonstrated that the varieties with good agronomic traits were Yunyan 99 and Yunyan 121 at resettle stage and vigorous growing stage,and Yunyan 97 at mature stage.For disease resistance,Yunyan 99 was the strongest,followed by Yunyan 121.As to chemical components,in each grade of leaves of the four varieties,total N content was relatively low,total sugar and reducing sugar contents were relatively high,and nicotine,Cl and K contents were appropriate.Especially,Yunyan 99 was of the most appropriate chemical component contents.In terms of economic traits,Yunyan 97 created the highest average price,yield and output value,next was Yunyan 99,then Yunyan 121,finally Yunyan 87.Comprehensively,Yunyan 99 is suitable for planting in Yongsheng tobacco area.
