摘要
[目的]研究打顶留叶数对丹东烟区烤烟产量、质量和焦油释放量的影响,为优质低焦油烟叶生产提供理论依据。[方法]通过安排留叶20片,18片(对照),16片3个处理的田间试验,调查分析在正常打顶时期不同留叶数对烤烟产质量及焦油释放量的影响。[结果]结果显示,打顶留叶20片时烟株农艺性状得到改善,田间发病情况较轻,产量、产值均高于对照,内在化学成分较协调,但烟气焦油释放量高。[结论]打顶留叶20片为较适宜处理,此时化学成分协调,经济效益更佳。
[ Objective ] Effects of topping remained leaf number on yield, quality and the tar content in flue-cured tobacco were studied to provide theoretical basis for low tar tobacco leaf production. [ Method ] The effects of topping remained leaf number （20,18,16 pieces of leaves per plant） on yield, quality and the tar content in flue-cured tobacco were studied. [ Result ] The results showed that agronomic traits had been improved with remaining 20 pieces leaves per plant. The plant height, distance between two inter nodes, leaf size, yield and quality increased when the re- mained leaf number was 20. However, the disease was mildly, the tar content was higher than other treatments. [ Conclusion ] It＇ s better for flue- cured tobacco to top remaining 20 pieces of leaves per plant , at this time, chemical composition is more coordinated and economic traits are bet- ter.
