关于烤烟“中棵烟”培育的若干思考

Some thoughts on ‘Zhongkeyan’ cultivation of flue-cured tobacco

烤烟理想株型塑造受多因素影响,进一步丰富和完善烤烟“中棵烟”内涵及培育理论与技术体系是实现烤烟特色优质、适产,促进原料保障上水平的重要途径之一。本文对当前烤烟理想株型调控理论与技术的研究进展进行了系统分析,并结合国内各烟区大力培育“中棵烟”的新形势,在总结前人成果的基础上,从系统论和大农业的角度丰富了“中棵烟”的内涵和指标体系,分析了影响烤烟理想株型塑造的因素,提出了通过协调株型-环境-措施三者关系来培育差异化“中棵烟”的途径,并对未来烟叶生产的发展进行了展望,以期为烤烟理想株型培育和现代烟草农业可持续发展提供理论指导。

The ideotype of flue-cured tobacco is affected by many factors.Further enriching and perfecting the connotation,cultivation theory and technical system of flue-cured tobacco‘Zhongkeyan’is an important way to achieve the coordinated development of multiple goals such as characteristics,high quality,suitable yield,high efficiency,and to promotethe level of raw material security.This article systematically analyzes the current research progresses on the regulation theory and technology of ideotype of flue-cured tobacco,and combines the new situation that‘Zhongkeyan’are vigorously cultivatied in various tobacco areas in China,enriches the connotation and index system of‘Zhongkeyan’from the perspective of system theory and large-scale agriculture,analyzes the factors that affect the ideal plant type of flue-cured tobacco,and proposes to cultivate differentiation by coordinating the relationship between plant type,environment and measures.‘Zhongkeyan’approach,and prospects for the development of tobacco leaf production in the future,with a view to providing theoretical guidance for the cultivation of ideal flue-cured tobacco plant types and the sustainable development of modern tobacco agriculture.
