摘  要:以烤烟品种JY-02为材料,于2007~2008年在吉林延边烟区进行田间试验,探讨深耕、深耕+秸秆覆盖、垄下深松、垄下深松+秸秆覆盖、传统耕作+秸秆覆盖、传统耕作(CK)等6种不同耕作方式对烤烟常规化学成分、经济指标及中性香气成分的影响。结果表明:不同耕作模式可以稳定钾、氯含量,协调初烤烟叶化学成分比例,使烟叶的产值、均价、上等烟比例均有不同程度的提高,深耕、秸秆覆盖、垄下深松明显促进烤烟叶片中性香气物质的积累,深耕+秸秆覆盖促进了类胡萝卜素降解产物类香气物质、棕色化产物类香气物质、苯丙氨酸类香气物质和新植二烯的形成,致香物质总量和其他不同种类致香物质含量有明显提高。不同耕作方式对烤烟常规化学成分、经济指标及中性香气成分有明显影响,深耕+秸秆覆盖对烤烟质量效应最好,适宜在延边烟区推广。The experiments were taking flue-cured tobacco varieties JY-02 as the material.During 2007-2008,the effects of 6 different tillage systems on the routine chemical components,economic characters and aroma substances of flue-cured tobacco were discussed in Yanbian city,Jilin Province.The results indicated that the different tillage systems could stabilize the content of potassium and chlorine and coordinate the proportion of the chemical component.The yield,the average price,the proportion of superior tobacco leaves had different degrees of improvement.The content of neutral aroma components was strongly prompted under the condition of deep-plough,straw mulch and ridge sub-soiling.The content of aroma components such as the contents of carotenoids,phenylalanine,products of browning reaction and neophytadiene were prompted by the deep-plough with straw mulch,the total amount of flavor matter and different types of aroma substances increased obviously.Different tillage systems of flue-cured tobacco had obvious effect on the routine chemical components,economic characters and aroma substances.The flue-cured tobacco quality by the deep-plough with straw mulch was better than any other treatment,which was worth promoting to the use in tobacco-growing areas.
