特色烤烟品种春蕾3号生产试验

Production Trail on Distinctive Flue-cured Tobacco Cultivar of Chunlei-3

采用品种比较的方法,分析研究了特色烤烟品种春蕾3号在当地生态适应性及其品质特征。结果表明:(1)春蕾3号在叶宽、茎围方面明显大于对比品种,但前期生长势弱于K326。(2)春蕾3号对青枯病的抗性低,但对气候斑点病具有较强的抗性;(3)春蕾3号中等烟率、桔黄率较高,但杂色烟率也高,表现出上等烟率低、产值偏低;(4)春蕾3号含氮化合物和碳水化合物含量较K326、云烟85略低;钾含量均高于K326、云烟85。

Ecological adaptability and quality of distinctive flue-cured tobacco cuhivars Chunlei-3 were analyzed in this paper. Through large areas of comparative experiment that each distinctive flue-cured tobacco cultivars, including Chunlei-3, K326 and Yunyan-85, were planted 0.23 hectares in Tianzhu ecological condition. The results showed that although the growing trend of Chunlei-3 in early weaker than K326, the leaf width and stem girth of it greater than those of contrastive cuhivar. The ability of Chunlei-3 resisting bacterial wilt was poor, but resisting tobacco weather fleck was strong. The rate of medium class and orange of Chunlei-3 was higher, though the rate of mottled tobacco was higher. And the rate of high class tobacco and output value was lower. Carbohydrate and nitrogen compounds content of Chunlei-3 were lower than those of K326 and Yunyan-85. Potassium content of Chunlei-3, however, was higher than others.
