| 摘 要： | 为提供制定烤烟生产中抗旱保收策略以及保险理赔业务的量化指标．在盆栽条件下，采用二因素随机区组设计，研究了不同生长时期干旱和不同干旱时间胁迫对烤烟品种G80产量和一些化学成分的影响．结果表明：干旱胁迫下的烤烟产量和含钾量等化学成分均明显下降，移栽20d后的烟株对干旱胁迫最敏感，此期烤烟产量和一些化学成分受影响最大，尤其是永久干旱处理对烤烟产量和一些化学成分的影响最严重．

| Abstract: | Effects of drought at different growth stages and different-day drought stress on yield and some chemical compositions of flue-cured tobacco(Nicotiana babacum L.) were studied in pot experiments designed by two-factor randomized block method to set the quota for anti-drought harvest strategy and insurance claim.The results showed that yield and some chemical compositions as potassium content of flue-cured tobacco leaves decreased distinctly.The transplanted flue-cured tobacco was most sensitive to the drought stress after 20 days.The yield and compositions were significantly influenced at this stage,especially under the permanent drought stress. |
