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 on the quality improvement of tobacco leaves and explore suitable application methods to promote the production of good quality tobacco leaves, under the field conditions, the effects of six different biological agents after topping on the physicochemical properties and aroma components of cured tobacco leaves were studied influences. The results showed that different biological agents could improve the quality of tobacco leaves. GA3 could significantly increase leaf length, leaf width, single leaf weight, leaf weight and tensile strength, and effectively reduce the nicotine content , Enhance potassium, total nitrogen content, improve the coordination of internal chemical components of tobacco and improve the aroma content, the overall effect is best, followed by auxin.
