不同烤烟新品系在黄平烟区的生态区适应性

Ecological Adaptability of New Flue-cured Tobacco Varieties(Lines) in Huangping Tobacco-growing Area

为烤烟新品系在黄平及类似烟区生产上的推广应用提供科学依据,采用田间试验方法,以当地主栽品种云烟116为对照,分析比较烤烟新品系6036和6028在黄平烟区的生育期、农艺性状、田间抗病性、经济性状、烤后烟叶外观质量和化学成分含量的差异。结果表明:田间抗病性6028最好,6036其次,云烟116最差;6036和6028的生育期与云烟116相当,农艺性状表现较云烟116略差,但田间长势强、整齐度好,易烘烤;烟叶化学成分的协调性优于云烟116,经济性状表现6036最好,云烟116其次,6028略差。6036可在黄平烟区推广种植;6028田间抗病性强,可在黄平烟区易发生根茎性病害区域作为优质烤烟补充品系推广种植。

To provide the scientific basis for promotion and application of new flue-cured tobacco varieties(lines)in Huangping and similar tobacco-growing areas,a field experiment was conducted to explore the difference in growth period,agronomic traits,field resistance,economic characters,appearance quality and chemical component content of cured tobacco of 6036 and 6028(new flue-cured tobacco lines)in Huangping tobacco-growing area with Yunyan 116 as the control.Results:The field resistance of 6028 was the best,followed by 6036 and Yunyan 116.The growth period and agronomic traits of 6036 and 6028 was similar to and slightly worse than Yunyan 116 respectively.6036 and 6028 had the advantages of vigorous growth,good uniformity and easy to cure.The chemical components of 6036 and 6028 were better than Yunyan 116.The economic characters of 6036 were the best,followed by Yunyan 116 and 6028.In conclusion,6036 could be popularized in Huangping tobacco-growing area and6028 can be popularized as a supplement of high quality flue-cured tobacco in the area prone to root-stem disease in Huangping tobacco-growing area due to its strong field resistance.
