摘 要:该文以皖南烟区2015年的气象因子和不同移栽期的农艺性状为依据,分析了气象因子与农艺性状的相互关系。结果表明:(1)气象数据分析显示,3月上旬平均气温偏低,为5.85℃,不适宜烟叶生长,3月下旬为最佳理论移栽时间。(2)3月10日前移栽,团棵期温度偏低,不利于腰叶发育。各移栽期成熟期雨量均较丰富,不利于烟叶成熟落黄。(3)3月19~29日移栽,制约烤烟生长发育的气象因子较少。

Abstract:Based on the meteorological factors and agronomic traits of different transplanting period of the 2015 in South Anhui Tobacco Area,the article analyzed the relationship between meteorological factors and agronomic traits.The results showed that: (1)Meteorological data analysis showed that the average temperature in early March was low,was 5.85℃, and it was not suitable for the growth of tobacco,and it was the best heoretical transplanting time in late March.(2)Transplanting before March 10th, the group stage temperature is not conducive to the development of middle leaves.The mature period rainfall of each transplanting stage is abundant, is not conducive to the maturity of tobacco middle leaves.(3) Transplanting in March 19th to March 29th,the meteorological factors that restricted the growth and development of flue-cured tobacco were less.

Key words:Flue-cured tobacco; Transplanting period; Meteorological factors; Agronomic traits

烤煙生长期间的气象因子是影响烟叶生长发育、质量和风格形成的最重要的因素之一[1-5]。移栽期不同,烟草生长期间的气象条件不同,烟草的生长发育及品质具有一定的差异。目前,有关移栽期的研究更多地侧重于对烟株气象条件、经济效益及烟叶品质影响的研究[6],而对不同移栽期气象指标与农艺性状的关系研究较少[3],尤其是针对安徽皖南烟区的气象因子与农艺性状的研究尚未见报道。为此,本研究根据皖南实际情况,通过烤烟不同移栽期气象因子与农艺性状的相关分析,分析影响烟叶生长发育的主要气象因子,以寻求最适宜的移栽期,为皖南特色优质烤烟生产提供参考依据。

1 材料与方法

1.1 供试材料 本实验于2015年3~7月在安徽省宣城市杨柳镇新龙村沪皖现代烟草农业高科技示范园进行,供试烤烟品种为当地主栽品种云烟97。

1.2 试验设计 考虑到生产优质烟……
