揭膜培土对烟株生长和烟叶品质的影响

摘要

[ Objective ] The aim of the study was to seek a good method of film uncovering and hilling for flue-cured tobacco in high altitude regions. [ Method ] Effects of film uncovering and hilling on growth and quality of flue-cured tobacco in Fengdu of Chongqing were studied.[ Result ] The results showed that under the same ecological conditions, film uncovering and hilling might improve the agronomic traits, such as plant height, stem girth and effective leaves were increased obviously. And the economic characters and appearance qualities were improved significantly, the rate of first class and medium leaves, the average price and the yield of tobacco was so higher that the usability of flue-cured tobacco leaves were increased obviously. [ Conclusion] The method of film uncovering and hilling improved growth and quality of flue-cured tobacco.%[目的]研究山地特殊气候和生态条件下的烤烟揭膜培土方式.[方法]以重庆市丰都县境内种植的烤烟品种云烟87为试验材料,研究揭膜培土对烟株生长和烟叶品质的影响.[结果]与不揭膜培土处理对比,栽后40 d揭膜培土效果较好.烤烟大田期农艺性状明显改善,其株高、茎围和有效叶片数显著提高;经济性状显著提升,上等烟比例、中等烟比例、均价和产量显著提高;且烟叶外观质量明显提高,其工业可用性进一步增强.[结论]揭膜培土有利于促进烟株生长和提高烟叶品质.
