| 摘 要： | 采用水培的方法，研究了不同有机酸对烟草生长发育和生理生化特性以及养分含量和积累的影响。结果表明，有机酸能够促进烟草的生长发育，增加叶绿素含量，提高硝酸还原酶、转化酶、淀粉酶活性和根系活力，降低烟草体内的丙二醛含量，提高N、P、K在烟叶中的积累量。但是不同种类的有机酸作用的程度不一样，苹果酸、乳酸、柠檬酸的效果相对较好，苯甲酸和腐殖酸次之。

| Abstract: | This paper studied the effects of different organic acids on growth, physiological and biochemical characteristics, nutrients content and accumulation of flue-cured tobacco by the method of water-culture. The results showed that organic acids could promote the growth of flue-cured tobacco, increase the content of leaves chlorophyll, the activities of nitrate reductase, invertase, amylase of leaves and root activities, reduce the content of MDA in flue-cured tobacco. Organic acids could also increase the accumulation of N, P, K in flue-cured tobacco. But effects of different kind organic acids was difference, malic acid, citric acid and lactic acid was better than that of benzoic acid and humic acid. |
