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。
In this paper, the effects of Zriconium [4] on tobacco growth, yield and quality were studied by single factor hydroponic and soil culture experiments with different concentrations of zirconium salt (Zro2 + as zirconium sulfate). The results show that the trace element zirconium can significantly promote the growth of tobacco, mainly in the promotion of root growth and nutrient absorption, so that plant height, leaf area, leaf thickness and leaf weight increase; tobacco yield up to 30% ; After the tobacco leaves turned into orange, adequate oil, nicotine content increased, while the more coordinated sugar and alkali; tobacco application of trace element zirconium suitable concentration range of 60 ~ 100mg / L, the optimum concentration of 80mg / L.
