摘  要：
气象条件对烤烟生产有着显著的影响,在调查汇总14 a耒阳市烤烟田间主要生育期数据基础上,结合历年气象数据,经相关分析:烤烟移栽期和终烤期的迟早分别与育苗和大田期间的日平均气温、有效积温、日照时数呈负相关,与降雨量呈正相关;而现蕾期的出现迟早则与1-3月的气温、积温、日照呈正相关,与降雨量呈负相关.以上结果表明,在烤烟生长季节随着气温和光照增加而加速生长发育进度,而2月低温寡照气象条件下具有诱导提前进入现蕾期的作用,加快生殖生长进度而造成烤烟早花问题.因此,在育苗期间的2月要采取增温补光措施,确保烟苗不受低温寡照天气影响,为当季烤烟生产奠定良好的基础.

摘  要：
Meteorological conditions have a significant impact on the production of flue-cured tobacco. Based on meteorological data over years and the data of main growth period in flue-cured tobacco fields of Leiyang City for 14 years, the correlation analysis showed that the drift of transplanting period and final baking period was negatively correlated with daily mean temperature, effective accumulated temperature and sunshine hours during the nursery and field periods, and positively correlated with rainfalls; the emergence of the bud stage was positively correlated with temperature, accumulated temperature and sunshine in January-March, and negatively correlated with rainfalls. The above results indicate that the growth and development progress is accelerated with the increase of temperature and illumination during the growing season of flue-cured tobacco; while the meteorological conditions of low temperature and less sunshine in February will result in an early entry into the bud stage and accelerate the reproductive growth progress, causing the early flowering problem. Therefore, in February during the nursery period, measures should be taken to increase the temperature and light to ensure that the tobacco seedlings are not affected by the low temperature and scant lighting weather, which lays a good foundation for the production of flue-cured tobacco in the current season.
