广西中烟正安基地适宜烤烟品种筛选试验

Screening appropriate flue-cured tobacco varieties for Zhengan base of Guangxi Tobacco Industrial Company

【目的】筛选适宜在正安基地种植的烤烟品种,为促进烤烟生产的可持续发展奠定基础。【方法】2012年在正安烟区对8个烤烟品种进行生物学性状、农艺性状、病害调查,分析和比较其经济效益、品质、外观质量、化学成分和感官质量等。【结果】在8个烤烟品种中,KRK26、云烟97、贵烟4号、南江3号和云烟202的生育期较长,有利于烟株田间的干物质积累与转化;KRK26、云烟97、贵烟4号在生长前期的长势较强,大田生长中后期趋于中等,符合优质烤烟的生长规律。相对于其他品种,贵烟4号的发病率较低,抗病性相对较好,烤后烟叶的产量、产值、均价、上中等烟比例均表现最好;各种化学成分较适宜,化学成分协调性较好;外观质量、感官质量总体表现较好,烟叶的香气质较好、香气量较足。【结论】建议在正安基地单元进一步推广应用贵烟4号。

【Objective】Appropriate tobacco varieties for Zheng’an base were screened to provide references for sustainable development of flue-cured tobacco production. 【Method】Biological traits, agronomic performance and disease of eight fluecured tobacco cultivars in Zheng’an base were investigated. Economic benefits, quality, appearance, chemical components and sensory quality in eight varieties were analyzed and compared. 【Result】Among the eight cultivars, KRK 26, Yunyan 97, Guiyan 4, Nanjiang 3 and Yunyan 202 varieties had longer growth duration, which was beneficial for dry matter accumulation and transition in field. KRK 26, Yunyan 97 and Guiyan 4 had strong growth vigor in early period and medium growth vigor in later period, which was consistent to growth rhythm of fine flue-cured tobacco. Compared to other varieties, Guiyan 4 had better disease resistance and showed low disease incidence in field. It also exhibited best tobacco leaf quality, output, mean price and economic benefits. Guiyan 4 had appropriate and harmonious chemical components, superior appearance and sensory quality, and good aroma. 【Conclusion】Considering all factors, it suggested that Guiyan 4 should be extended in Zheng’an tobacco base.
