摘要：就9个不同移栽期和采收期组合处理对烤烟产量、品质的影响进行了研究。结果表明，不同移栽期和采收期对烤烟生育期、农艺性状影响不大；但对烤烟经济性状和化学成分影响较大，随着移栽期的推迟，烤烟产值增加；正常时间采收的产值高于推迟采收的产值；不同移栽期和采收期对烤烟化学成分的影响较大，但规律不明显。以延迟14 d移栽+正常采收处理的综合表现较优。

Abstract：The effects of nine combinations of different transplanting time and harvest time on yield and quality of flue-cured tobacco were studied. The results showed that different transplanting time and harvest time had little effect on growth period and agronomic traits of flue-cured tobacco； while the influence on production output and chemical composition of flue-cured tobacco was greater. As the transplanting time delayed， the output of flue-cured tobacco increased. The yield of normal harvest time was higher than that of delayed harvest time. Different transplanting period and harvest time had greater influence on chemical composition of flue-cured tobacco， of which the rule was not obvious. Delayed transplanting 14 d + normal harvest treatment was better than the others.

攀枝花烟区地处横断山脉东南，属典型的南亚热带季风型气候，年降水量800～1 700 mm，具有年温差小、日温差大、雨量充沛、光照充足等气候特点，是我国烤烟最适宜种植的区域之一，所以当地烟叶是国内众多名牌卷烟产品不可替代的主要原料。烤烟适宜移栽期和采收期是生产优质烟叶的重要环节[1-8]，烤烟移栽时间受种植地区土壤、气象因素、品种、栽培模式等因素的影响[2，9]，移栽过早、过晚均不利于烤烟生长；适时采收是提高烟叶成熟度的根本措施，但在攀枝花烟区尚未见到系统地研究移栽期和采收期对烤烟产量与质量影响的报道。课题组针对攀枝花地区烤烟不同移栽期和采收期对产量与品质等的影响进行了试验研究，以期为当地优质烟叶生产提供有益的参考。
