论烟草集约化轻简育苗及其发展方向

中国烟草育苗已初步实现集约化、规范化，但总体程度不高。育苗成本高，技术环节多，剪叶、消毒等苗期管理工作费时费工，进一步限制了烟叶生产的可持续发展，现有的集约化育苗理念和技术体系已难以适应新形势的发展。为降低育苗成本、提高成苗素质，对烟草集约化轻简育苗的内涵进行阐述，综述了烟草育苗现状中的优缺点，形成了包括轻简育苗方式、生态化绿色育苗基质、机械数字化作业技术等轻简育苗技术，并对烟草集约化轻简育苗进行了展望。

Discussion on Intensive Simplified and Labor Saving Seedling of Tobacco and Development Direction

Intensive simplified and labor saving seedling has basically formed in China. Reaserch of simplified and labor saving seedling has realized high quality and efficient production of tobacco seedlings. The cost of seedling is expensive, the links of technology are complex, cuttingleaves and disinfection need much time and labor, has limited the sustainable development of production of tobaccofurther. For reducing the cost of seedling improving the quality of seedling, the author had stated the concept of intensive simplified and labor saving seedling of tobacco, summarized the advantage and disadvantage of the tobacco seedling in current situation, formed simplified and labor saving seedling technology including the way of simplified and labor saving seedling, ecological seedling substance, mechanical and digital technology, and looked intensive simplified and labor saving seedling of tobacco into future.
