摘 要:研究了增施镁和硼对山地紫色土上烤烟农艺性状、产量、常规化学成分和烟叶矿质元素含量的影响。结果表明,施用镁、硼肥对烤烟的农艺性状、产量、品质有明显的良好效应。在供试条件下,单施硫酸镁187.5 kg/hm2与混施150 kg/hm2镁肥和30 kg/hm2硼肥组合表现最佳;硼砂施用量不宜超过30 kg/hm2,过量会抑制烤烟生长发育,产量和品质都明显下降。The effects of adding Mg and B on the agronomy characteristics, contents of mineral elements, yield and quality of flue-cured tobacco in slopeland of purple soil were observed in this study. The results showed that obvious good effects on those quality indexs were abtained by adding of Mg and B. The results also indicated that, in the field-testing condition, the best performances were additions of single magnesium sulfate 187. 5 kg/hm2 or mixtures of magnesium sulfate 150 kg/hm2 and borax 30 kg /hm2 ; the borax added to soil would better no more than 30 kg/hm2, for it would inhibit the tobacco growth over this number, the yield and quality of flue-cured tobacco were obviously decreased too.
