不同灌溉方式对初烤烟叶中性香气物质含量的影响

采用大田试验研究浇灌、沟灌和喷灌3种灌溉方式对烤后烟叶中性致香物质含量的影响，探讨提高烟叶香气物质含量的水分管理技术。结果表明：喷灌灌溉方式极显著提高中上部位烟叶中性致香物质含量，与浇灌和沟灌相比，喷灌处理上桔二(B2F)等级烟叶中性致香物质含量分别提高了8.1%和42.9%，中桔三(C3F)等级烟叶分别提高了26.3%和27.9%，差异均极显著。表明间歇性喷灌补水是一种较优的烤烟灌溉方式，在烤烟成熟期，对改善中上部位烟叶香气量效果显著。

Effects of Different Irrigation Methods on the Contents of Neutral Aromatic Substance in Flue-cured Tobacco Leaves

Effects of different irrigation methods on neutral aromatic substance content of flue-cured tobacco leaves were studied by field experiment to screen irrigation method which can improve tobacco leaves aroma quantity. The results showed that sprinkler irrigation significantly increased middle and upper part tobacco leaves neutral aroma substance content. compared to water irrigation and furrow irrigation, sprinkler irrigation B2F grade tobacco leaves neutral aroma substance content increased by 8.1% and 42.9% respectively, C3F grade tobacco leaves neutral aroma substance content increased by 26.3% and 27.9% respectively which indicated sprinkler irrigation is a kind of optimal irrigation method for flue-cured tobacco planting, also a kind of usability way to improve aroma quantity.
