摘要:

为提高肥料利用率、提升烟叶品质、增加烤烟产量及促进烟农增收,本研究通过肥水协同供应模式探讨其对烤烟生长发育及产量的影响,旨在筛选出适宜吉安优质烤烟生产的最佳模式。试验设置3个处理:CK(常规施肥)、T1(常规施肥+增施1次落黄肥)、T2(常规施肥+增施2次落黄肥)。结果表明:在农艺性状方面,施用落黄肥可促进烟株生长发育及上部叶开片,以T2处理表现最优。在经济性状方面,施用1次或2次落黄肥均有助于改善烟叶经济指标。在外观品质方面,T1与T2的总分均高于CK,且二者间无差异。在化学成分方面,各处理总糖、还原糖和烟碱含量均有所降低,钾和氯含量升高,两糖比、糖碱比和钾氯比得到改善,化学成分协调性提高。在感官品质方面,感官总分表现为T2>CK>T1。综合来看,T2处理(增施2次落黄肥)对提升烟叶品质具有较好效果。

Abstract:

To improve fertilizer utilization efficiency,enhance leaf quality,increase flue-cured tobacco yield,and promote farmers' income,this study investigated the effects of water-fertilizer synergistic supply models on the growth,yield,and quality of flue-cured tobacco,aiming to identify the optimal model suitable for high-quality tobacco production in Ji'an. Three treatments were set up:CK(conventional fertilization),T1(conventional fertilization + one additional application of yellow-ripening fertilizer),and T2(conventional fertilization + two additional applications of yellow-ripening fertilizer). The results showed that in terms of agronomic traits,applying yellow-ripening fertilizer promoted tobacco plant growth and development as well as upper-leaf expansion,with T2 performing the best. Economically,both one and two applications of yellow-ripening fertilizer helped improve the economic indicators of tobacco leaves. Regarding appearance quality,the total scores of T1 and T2 were higher than that of CK,with no difference between T1 and T2. In chemical composition,total sugar,reducing sugar,and nicotine contents decreased,while potassium and chlorine contents increased;the ratios of reducing sugar to total sugar,total sugar to nicotine,and potassium to chlorine were improved,thereby enhancing the coordination of chemical components. In sensory quality,the total sensory scores followed the order T2>CK>T1. Overall,the T2 treatment(with two additional applications of yellow-ripening fertilizer)demonstrated a relatively clear improving effect on tobacco leaf quality.
