锆对烟草生长和产量、质量影响的研究

Study on the Effects of Trace Element Zirconium on Tobacco Growth, Yield and Quality

摘要:

本文通过不同浓度锆盐(Zro²⁺为硫酸锆)单因子水培和土培试验, 研究微量元素锆(Zriconium)^[4]对烟草生长和产量、质量的影响。研究结果表明:微量元素锆对烟草生长有明显的促进作用, 主要表现在促进根系生长, 增强养分吸收, 使烟株株高、叶面积、叶片厚度和单叶重增加; 烟叶产量最高达30%; 烘烤后烟叶变为桔黄色, 油分充足, 烟碱含量升高, 而糖碱比较协调; 烟草施用微量元素锆的适宜浓度范围为60~100mg/L, 最佳浓度为80mg/L。

Abstract:

Both water cultures using diferent concentrations of Zro²⁺ and pot experiments were conducted to study the effects of trace element-Zirconium on tobacco growth, yield and quality. The result shows: (1)The trace element-Zirconium can obviously accelerate the growth of tobacco, the main reflections are that it can accelerate the root growth, strengthen the nutrien absorbtion and raise the plant height, leaf area, thickness and single leaf weight. (2)The yield of tobacco couldincrease highest by 30%. (3)Flue-cured tobacco leaf would turm orange, with sufficient tobacco oil, increased nicotine content and coordinated sugar and alkali. (4)The suitable range of trace element-Zirconium is 60～100 mg/L and the best is 80 mg/L.
