摘　　要：为确定湖北烤烟区基肥的合理施用时期,2007~2008年在宣恩县、咸丰县、保康县开展了烟草基肥施用时期试验,研究了基肥施用时期对烟叶的生长发育和产质量的影响,结果表明：基肥施用时期以移栽前20 d施用最好,有利于烟株的生长发育和形成最佳的产量和产值;基肥施用时期对烤烟的主要化学成分有一定的影响,但各个试验点各处理的烟叶化学成分没有表现出较强的规律性;基肥施用时期对烤烟的感官质量影响较大,于栽前20 d施基肥处理的结果优于其它处理,香气质有所改善,香气量有所增加。Experiments were conducted from 2007 to 2008 in Xuan＇en county,Xianfeng county and Baokang county to study effects of base fertilization on growth,development,yield and quality in flue-cured tobacco applied at different stages.Results showed that 20 days before transplanting was the optimal stage for applying base fertilizer,with best plant type.Different stages for base fertilizer application showed different effects on main chemical components in flue-cured tobacco,with no obvious regularity.Stage of applying base fertilizer also affected sensory quality.Tobacco with base fertilizer applied 20 days before transplanting showed improvement in quantity and aroma.
