【摘要】 研究了大田常规措施下牛粪用量对烤烟烟叶中性致香物质含量的影响.结果表明:牛粪对烤烟上部叶影响最大,其次是下部叶,对中部叶影响最小;各处理烤烟上部叶、中部叶中总致香物质含量增加,下部叶含量降低;各处理不同部位烟叶中类胡萝卜素类、苯丙氨酸类、棕色化产物、新植二烯等致香物质含量均较对照有很大提高.大田牛粪用量为3000 kg/hm2时增香效果最好,显著缩小了部位间差异,致香物质含量比较协调.更多还原

【Abstract】 The effect on the relationship between the contents of neutral aroma components and the amount of cow dung in the field under common measure were researched.Results showed that adding different weight of cow dung brought different effect in the flue-cured tobacco leaves.Among them,the upper leaves were the most,the lower leaves took second place,and the cutter leaves were the third.The total contents of neutral aroma components in the upper and the cutter leaves increase,but the contents in the lower leaves reduce.Compared with the control treatment,the contents of carotenoid,phenylalanine,products of browing reaction and neophytadiene were greatly increased in every treatment.As far as the total content of neutral aroma components was concerned,good effect was obtained from the adding of cow dung at 3 000 kg/hm2.The discrepancy between the leaves in different positions was diminished.更多还原
