摘　　要：为研究常用生物制剂对烟叶品质提升的影响,探索适宜施用方法促进优质烟叶生产,在大田条件下,研究了打顶后喷施6种不同生物制剂对烤后烟叶理化性状及致香物质含量的影响。结果表明:不同生物制剂对改善烟叶品质均有一定作用,赤霉素(GA3)能显著提高烟叶的叶长、叶宽、单叶重、叶质重和抗张性,有效的降低烟碱含量,提升钾、总氮含量,改善烟叶内在化学成分的协调性,并提高致香物质含量,整体效果最优,生长素次之。In order to study the effect of commonly used biological agents for improving tobacco quality, and explore suitable method to promote high quality tobacco production, field experiment was carried out to study the influence of 6 different biological agents on the physical and chemical properties, and the contents of neutral aroma components of tobacco after topping. The results showed that different biological agents had certain effects on tobacco leaf quality. Gibberellin（ GA3 ） could improve the leaf width and length, single leaf weight, leaf density and stretching power. Thus, it effectively reduced the nicotine content and increased the contents of potassium and total nitrogen ; improved the coordination between chemical components inside of tobacco leaves ; and increased the aroma components content. So, gibberellin （GA3） had the optimal overall effect, and auxin took second place.
