在湖南3大烟区的永州市、浏阳市、桑植县进行客土盆栽试验,探讨气候、土壤及其互作对湖南烟叶还原糖、烟碱和总氮含量的影响。结果表明:1烟叶还原糖、烟碱和总氮3种化学成分的变异强度中等,且其变异强弱按该顺序依次递减。2气候、土壤及其互作对烟叶还原糖、烟碱和总氮3种化学成分的影响程度不同,气候对它们均具有强影响效应,土壤对它们无明显影响;气候与土壤的互作对它们的影响效应年际间有差异。气候对还原糖、烟碱和总

The impact of climate, soil and their interactions on reducing-sugar, nicotine and total nitrogen contents of flue-cured tobacco leaf were investigated through pot experiments in Hunan high-quality tobacco regions of Yongzhou, Liuyang and Sangzhi from 2006 to 2007. The experiments disclose the following results; First, the variation coefficients of reducing-sugar, nicotine and total nitrogen of tobacco leaves are of medium intensity and the intensity decreases in the order of reducing-sugar, nicotine and total nitrogen. Furthermore, climate, soil and their interactions impact reducing-sugar, n...
