湖南中烟工业有限责任公司"土壤和气候及其互作对湖南烤烟品质的影响"

本校为第一机构

为探讨土壤和气候及其互作对湖南烤烟品质的影响,在其它栽培条件一致的前提下,分别在湖南相距较远的3个主产烟区(湘西北桑植县,湘中浏阳市,湘南永州市)将各自本土和另2个产地客土同地盆栽烤烟K326,在烟叶收获期取各处理的中部烟叶分别检测其糖与总植物碱的含量,并统计分析土壤和气候及其互作对这两个指标的影响.结果表明,在湖南主产烟区,不同气候条件下生长的烤烟糖与总植物碱含量存在显著差异;而不同地区土壤条件下种植的烤烟这两项化学成分含量差异均没达到显著水平.土壤和气候及其互作效应对这两个化学指标含量变异的贡献率不一样,气候对它们变异的贡献率为72%,60%;其次为气候与土壤的互作效...

Pot experiments were carried out to study effects of soil, climate conditions and their interaction on reducing sugar and total alkaloid content in flue-cured tobacco from 3 main production regions which are geographically far away in Hunan. K326 was planted on each pot soil where other planting conditions maintaining as consistently as possible. Results showed that there were significant differences in reducing sugar and total alkaloid in flue-cured tobacco grown in different climate conditions in Hunan, while no significant differences among different soil conditions. The contributing ratios...
