烟苗移栽时间对田间病害防控的影响

Effects of Transplanting Time on the Control of Tobacco Diseases

烟苗移栽时间对田间烟株的生长和烟叶品质有显著的影响,近年来,越来越多的证据和报道表明,烟苗移栽时间和田间烟草病害的发生也有密切的关联,烟苗移栽时间推后加剧了田间烟草青枯病的发生.因此,各烟区也在积极探索通过烟苗移栽时间前移控制烟草青枯病的防控措施,但目前对于烟苗移栽时间和烟田病害发生关系的研究和报道还较少.本文主要针对烟苗移栽时间的确定原则以及与田间病害发生的关系进行了总结和梳理,在确定各烟区烟苗移栽期方面提出了相关建议,旨在帮助各烟区正确合理地确定烟苗的移栽时间,提高病害防控效果,帮助烟农增产增收.

The timing of seedling transplanting has a significant influence on the growth of tobacco plants and the quality of tobacco leaves.In recent years,there have been more evidences and reports about the close relationship between tobacco transplanting time and the occurrence of tobacco diseases in the fields,and the postponing of tobacco transplanting time may aggravate the occurrence of tobacco bacterial wilt in the fields.However,there are few studies and reports about the relationship between the transplanting time and the occurrence of tobacco diseases.This paper summarizes the principles for determining seedling transplanting time,and the relationship between transplanting time and the occurrence of tobacco diseases.In addition,some suggestions are putting forward in this paper to determine the transplanting time,in order to help the tobacco farmers to increase their yield and income.
