木醋液能够促进植物生长,提高植物抗病性。为探讨木醋液施用方式与烟草品质和病害防治的关系,通过田间试验研究了不同浓度木醋液叶面喷施和灌根处理对烤烟品质及病害的影响。结果表明:各处理均能不同程度地改善烟叶品质,提高烟叶产量,防治烟草病害,降低其发病率。叶面喷施(400倍)+灌根(1 000倍)能提高烟草总糖和还原糖含量,促进烟草中性致香物质的积累,提高烟叶香气质量;叶面喷施(500倍)显著提高了烟草钾含量和烟叶单叶重,进而使烟草产量增加。木醋液能协调烟草化学成分,降低烟碱和总氮含量。木醋液处理在生产品质优、产量高的烤烟方面起了重要作用。
Wood vinegar can promote plant growth, improve plant disease resistance. In order to explore the relationship between the application of wood vinegar and tobacco quality and disease prevention and control, field experiments were conducted to study the effects of different concentrations of wood vinegar spraying and irrigating roots on the quality and disease of flue-cured tobacco. The results showed that all the treatments could improve the quality of tobacco leaf to some extent, increase the yield of tobacco leaf, prevent tobacco disease and reduce its incidence. Leaf foliar application (400 times) + rooting (1000 times) increased total sugar and reducing sugar content, promoted the accumulation of neutral aroma components in tobacco leaves and improved the aroma quality of tobacco leaf; Increased the potassium content of tobacco and single leaf weight of tobacco, thereby increasing the production of tobacco. Wood vinegar can coordinate the chemical constituents of tobacco and reduce nicotine and total nitrogen. Wood vinegar treatment in the production of high quality, high yield tobacco has played an important role.
