调查了2008和2009年邵阳地区烤烟种植品种分布情况及烟区的品种布局现状,认为邵阳烟区品种布局存在主栽品种单一、遗传多样性基础匮乏,特色考验品种匮乏、布局无区域特色等问题,针对品种布局问题提出应加大现有主栽品种的调整力度,加强优良品种的配量技术研究,优化现有品种的合理布局。 Investigated the distribution of flue-cured tobacco planting varieties and the distribution of tobacco varieties in Shaoyang in 2008 and 2009, and concluded that there were single cultivars, lack of genetic diversity, lack of characteristic test varieties and no regional characteristics in the layout of Shaoyang tobacco-growing areas , According to the issue of variety layout, we should increase the adjustment of existing cultivars, strengthen the research on dosage technology of fine varieties, and optimize the rational layout of the existing varieties.
