烟苗根系亚健康原因分析及对策研究

针对当前洛阳烟区烟草漂浮育苗过程中,烟苗根系常见的亚健康问题,本文从烟苗根系发育特点、亚健康特征表现及根系亚健康产生的原因展开分析论述,并结合烟叶生产漂浮育苗技术,就改善烟苗根系发育中易出现的根系侧根数量不足、螺旋根偏多、隐性病菌感染等亚健康问题,从烟草育苗方式改革、育苗过程管理、营养调控和激素调控方面,探索促进烟苗根系发育、改善烟株根系亚健康问题的对策,为有效解决烟苗根系亚健康根系问题,切实提高洛阳烟区烟苗质量提供生产依据,进一步筑牢洛阳烟区烟叶高质量发展基础。

Cause Analysis and countermeasures of sub-health of tobacco seedling root system

In view of the common sub-health problems of tobacco seedling root system in floating system of tobacco in Luoyang, this paper analyzes the characteristics of tobacco seedling root system development, the characteristics of sub-health and the causes of sub-health of tobacco root system, combined with the technology of floating seedling production in tobacco leaf, the sub-health problems such as insufficient number of lateral roots, more spiral roots, and infection of recessive bacteria, which often occur in the development of tobacco seedling root system, were improved, in order to solve the problem of sub-health root system of tobacco seedling effectively, the countermeasures of promoting the development of tobacco seedling root system and improving the sub-health problem of tobacco root system were explored from the aspects of the reform of tobacco seedling raising mode, the management of seedling raising process, the regulation of nutrition and the regulation of hormones, to improve the quality of tobacco seedlings in Luoyang and build the basis for the development of high quality tobacco leaves in Luoyang.
