烤烟复合型叶面肥对烟叶降碱增香提质的作用研究

Study on Effects of Compound Foliar Fertilizer on Reducing Nicotine Content,Improving Aroma and Quality of Flue-cured Tobacco(Nicotiana glauca L.)

[目的]为了掌握2种叶面肥对烤烟(Nicotiana glauca L.)外观和内在品质的作用效果。[方法]进行烤烟叶面肥大田对比试验。[结果]烟株打顶后进行2次复合型叶面肥喷施处理,能够明显促进上部叶开片,上部叶面积增幅7.9%～20.2%;烟叶结构、油分、色度、身份等外观质量得到明显改善;烟碱含量适宜,化学成分协调性得到改善,烟叶关键香味物质含量和评吸质量明显提高。[结论]烤烟复合型叶面肥的使用效果明显优于同类叶面肥,具有较高的推广应用价值。

[Objective] In order to grasp the effects of two types of foliar fertilizers on appearance and inter quality of flue-cured tobacco.[Method] Contrast test with foliar fertilizers in field was conducted.[Result] The results indicated that spraying tobacco leaves with compound foliar fertilizer twice could promote tobacco upper leaves spreading speed,upper leaves area growth rate was 7.9%-20.2%;Tobacco leaves＇ appearance quality,such as structure,oil content,chromaticity and identify,were progressed evidently;Nicotine content of leaves was proper;harmony of chemistry component was improved;Leaves＇ key aroma matter content and suck quality were progressed evidently.[Conclusion] Tobacco compound foliar fertilizer is significantly superior to other alike products,which are recommended to further popularized in leave fertilizer production.
