| 摘 要： | 通过对烤烟补充锰和镁元素,研究3种浓度对于烤烟农艺性状和主要生理生化指标的影响。结果表明：在150～250 mg/kg范围内的锰素对于烤烟的株高、茎围、叶绿素a、叶绿素b有明显的促进作用;而烤烟中的叶绿素与镁的添加量呈正比,但受其他阳离子拮抗作用限制,吸收能力有限。

| Abstract: | Through supplementary manganese and magnesium elements on tobacco,the effect of the three concentrations on tobacco agronomic and physiological and biochemical indexes were studied.The results showed that there was significant promoting role in the range of manganese 150-250 mg/kg for tobacco plant height, stem girth, chlorophyll a, chlorophyll b.There was positive relationship between chlorophyll in tobacco and added magnesium amount, but it was limited by the antagonism of other cations, absorptive capacity was limited. |
