[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40d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。
[Objective] The research aimed to study the flue-cured tobacco strip-mulching and soil-taking methods under special climate and ecological conditions in mountainous areas. [Method] With Yunfu 87, a flue-cured tobacco variety planted in Fengdu County, Chongqing Municipality, as the experimental material, the effects of film-removing culture on tobacco plant growth and tobacco quality were studied. [Result] Compared with the soil-unloading treatment, the effect of soil-removing and soil-harvesting was good 40 days after transplanting. The agronomic traits of flue-cured tobacco significantly improved in the field, and its plant height, stem circumference and effective leaf number increased significantly. The economic traits significantly improved, the superior tobacco ratio, middle tobacco ratio, average price and yield increased significantly. Industrial availability is further enhanced. [Conclusion] Removing the film soil and helping to promote tobacco plant growth and improve the quality of tobacco.
