| 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。

Effects of Different Transplanting and Harvest Dates on Yield and Quality of Flue-cured Tobacco Leaves |
| |
| Abstract: | In this study, the effects of nine different combinations of transplanting and harvest dates on yield and quality of flue-cured tobacco leaves were investigated. The results showed that different combinations of transplanting and harvest dates had few effects on growth period and agronomic characters of tobacco plants but exerted remarkable effects on economic characters and chemical composition of flue-cured tobacco leaves. With the postponing of transplanting stage, output value of flue-cured tobacco leaves increased. Output value of flue-cured tobacco leaves in C1 treatment (normal harvest) was higher than that in C2 (harvest 7 d later) and C3 (harvest 14 d later) treatments. Different combinations of transplanting and harvest dates had significant effects on chemical composition of flue-cured tobacco leaves, which exhibited no obvious law. Overal , flue-cured tobacco leaves in T3C1 treatment (transplanting 14 d earlier, normal harvest) displayed excel ent performance com-pared with other treatments. |
