研究结果表明,在烤烟生长季节干旱条件下,随着补水数量的增加,烟株生物学各项指标表现出指标上升、长势更好的趋势。在烤烟生长旺长期气候干旱、土壤水分不足成为限制烤烟生产的主要因素,成熟期适时适量补水可以明显改善烟叶的化学成分,提高烟叶的内在质量。在旺长期与成熟期均要分别进行补灌,补灌水总量达到在8~10 kg/株左右。
The results showed that under the drought condition of flue-cured tobacco growing season, with the increase of water supplement quantity, the indicators of tobacco biology showed the trend of rising and growing better. In the long-term growth of flue-cured tobacco, climate drought and insufficient soil moisture have become the main factors limiting the production of flue-cured tobacco. Appropriate amount of water replenishment at maturity can significantly improve the chemical composition of tobacco leaves and improve the intrinsic quality of tobacco leaves. In Mongolian long-term and mature period were to fill irrigation, fill the total amount of irrigation water reached 8 ~ 10 kg / plant or so.
