摘要 为了探索干旱胁迫对烤烟的影响,在利川开展烤烟不同生育期不同干旱程度對烤烟某些理化特性及产质量影响的研究。结果表明,在烟叶干旱过程中,随着干旱程度的加深,烟叶的光合指标和部分生理指标均受到较大影响,各项光合指标和生理指标都呈降低趋势。烟叶的农艺性状也受到影响,随着干旱程度的加重,烟叶生长受阻,植株矮化,烟叶不能正常成熟,烘烤后烟叶的质量很差,对经济性状造成很大影响。因此,在烟叶生产中应加强应对高温干旱的应对措施,避免旱灾损失。

Abstract In order to research the effects of drought stress on flue-cured tobacco, the experiments of different drought degrees at different growing stages of flue-cured tobacco on physicochemical properties, yield and quality were carried out in Lichuan. The results showed that the photosynthetic indexes and some physiological indexes of tobacco leaves were greatly affected with the deepening of drought stress, and all the photosynthetic indexes and physiological indexes showed a decreasing trend. With the increase of drought degree, the agronomic traits of tobacco leaves were also affected. The growth of tobacco leaves were hindered, the plants were dwarfed, the tobacco leaves could not mature normally, and the quality of tobacco leaves after baking was poor, which had a great impact on economic traits. Therefore, the measures to deal with high temperature and drought should be strengthened in tobacco production to avoid drought loss.

烟草(Nicotiana tabacum L.)是我国重要的叶用经济作物之一,烟叶生产是烟区农民增收的主要来源,在国家和地区经济发展中发挥了重要作用[1-2]。烟叶生长前期要求有充足的水分,以满足营养生长需求,而我国烟区主要集中在缺乏灌水条件的丘陵山地且旱情频发,干旱胁迫已经成为烤烟优质稳产的主要限制因子之一[3]。……
