烟叶霉烂病产生原因及防治措施

Causes and Control Measures of Tobacco Leaves Mildew

摘要: 为了有效控制烘烤过程中霉烂病的发生，本研究通过现状调查，系统分析了烘烤过程中烟叶霉烂病的发病情况及发病条件。研究结果表明：低温多雨环境、烘烤工艺不当、烤房结构缺陷等因素与烟叶霉烂病的发生密切相关。基于此，提出并采取了综合防治技术体系，包括科学采收、规范编装、精准温湿度调控、烤房结构改造及药剂辅助防控。通过技术集成应用，烟叶霉烂病的发生率由6.95%降低到0.64%，该技术得到全面推广应用，有效保障了烟叶品质，为绿色烘烤提供技术支撑。

Abstract: To effectively reduce the occurrence of tobacco leaves mildew during flue curing process, this study systematically investigated the incidence patterns and contributing factors through current situation surveys. The results indicated that the occurrence of tobacco leaf mildew was closely related to factors such as low temperature and heavy rainfall, improper flue curing techniques, and structural defects of the curing barn. Accordingly, an integrated prevention and control system was developed and implemented, such as scientific harvesting, standardized packaging, precise temperature and humidity regulation, renovation of the curing barn structure, and use of chemical agents for auxiliary prevention and control. The incidence of tobacco leaves mildew decreased from 6.95% to 0.64%. This technical system has been widely adopted during flue curing process, effectively ensuring tobacco quality and providing technical support for green curing practices.
