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。
In order to determine the reasonable application period of basal fertilizer in flue-cured tobacco in Hubei Province, the experiment of basal application of tobacco was carried out in Xuan’en County, Xianfeng County and Baokang County from 2007 to 2008, and the effects of basal fertilizer application period on the growth and yield and quality of tobacco were studied. The results showed that the best application of basal fertilizer for 20 d before transplanting was conducive to the growth and development of tobacco plants and the formation of the best yield and value. The basal fertilizer application period had some influence on the main chemical components of flue-cured tobacco. However, The chemical composition of the treated leaves did not show a strong regularity; the base fertilizer application period had a great effect on the sensory quality of flue-cured tobacco. The results of applying the basal fertilizer 20 days before planting were superior to other treatments, the aroma quality was improved, Has increased.
