摘　　要：以湖南省主栽烤烟品种K326和云烟87为对照,评价了烤烟新品种HN2146在湖南衡阳地区的生产适用性,并研究其适宜施肥量。结果表明,HN2146生育进程与对照品种相当,其采烤叶数较多,茎围较大,节距居中,腰叶叶面积较大,叶面积指数较大,产量、产值、均价、上等烟比例、中等烟比例与中上等烟比例较高,对黑胫病抗性较好,化学品质较好;在中肥水平(N 154.875 kg/hm ^2、P 2O 5 141.75 kg/hm^ 2、 K 2O 505.625 kg/hm ^2)下,HN2146的经济性状、抗病性、烟叶化学品质均表现较好。因此,HN2146综合表现较好,适宜在湖南衡阳地区推广种植;HN2146的适宜施肥水平为中肥水平。With K326 and Yunyan 87 as the control, we evaluated the production applicability of new flue-cured tobacco variety HN2146 in Hengyang Area in Hunan Province.And the proper fertilizing amount was researched.Results showed that HN2146 had almost the same growth process with that of control, but had relatively more flue-cured leaves, greater stem girth, moderate node distance, greater area of waist leaves and leaf area index, as well as greater yield, output value, average price, proportions of high- and middle-class tobaccos.HN2146 showed relatively better economic characters, disease resistance and chemical quality of tobacco leaves.Therefore, HN2146 showed relatively good comprehensive performance, which was suitable to be planted in Hengyang Area in Hunan Province.And the proper fertilizer level was middle (N 154.875 kg/hm^2,P 2O 5 141.75 kg/hm ^2,K 2O 505.625 kg/hm^2).
