摘要： 为探索叶面喷施腐植酸钾对烟草品种‘红花大金元’（以下简称‘红大’）产量、品质的影响，改善‘红大’的烤性和可用性，以烟草品种‘红大’为材料，采用随机区组设计，在团棵期、旺长期、现蕾期各喷施腐植酸钾1次，并比较成熟期烟叶农艺性状和烤后烟叶产量、产值。结果表明：喷施腐植酸钾后‘红大’处理的相关农艺性状与对照相比没有显著差异；而烤后烟叶产量、产值、上等烟比例、中上等烟比例较对照分别提高了7.25%、9.22%、6.23%和8.49%；主要化学成分组成较对照更加协调，其中还原糖、总糖含量、氯含量较对照分别降低了10.09%、17.54%、53.85%，差异达到显著水平；总氮、钾含量较对照分别提高了13.58%、21.09%，差异达到极显著水平；总植物碱含量差异在两者间不显著。‘红大’处理评吸质量保持了‘红大’优异的质量风格，两者等级均为较好-，‘红大’处理的评分稍高，但不明显。腐植酸钾作为一种环保的绿色有机钾肥，可在烟叶生产中用于改善其产量和品质。

Abstract: For improving the flue-cured characteristic and usability of tobacco variety ‘Honghuadajinyuan’, and clarifying the effect of foliar application of potassium humate (HA-K) on the yield and quality of ‘Honghuadajinyuan’. A random block design was used in this research, HA-K was applied once in each resettling stage, fast-growing stage and budding stage; agronomic traits were evaluated in mature stage, and yield and output value were calculated after flue-cured. Results showed that: there were no significant differences between fertilizer-treated ‘Honghuadajinyuan’ and CK in yield-related leave characters; However, compared with control, the yield, output value, proportion of superior leaves, and proportion of middle and superior leaves were significantly increased by 7.25%, 9.22%, 6.23% and 8.49%, respectively; chemical components were more harmonious than that of CK, content of reducing sugar, total sugar, and chlorine were significantly decreased by 10.09%, 17.54% and 53.85%, respectively, meanwhile, total nitrogen and potassium were significantly increased by 13.58% and 21.09%, there were no significant differences in total alkaloids; the fertilizer-treated ‘Honghuadajinyuan’ maintained smoking quality of regular ‘Honghuadajinyuan’, and no significant differences in smoking score with control. In conclusion, the HA-K, as an environmental-friendly organic fertilizer, was available for improving yield and quality of flue-cured leaves in ‘Honghuadajinyuan’ production.
