摘要： 为探索有机烟生产的合理追肥次数，2012年在贵州省福泉市进行了相同追肥量下不同追肥次数对有机烟叶生长发育和产质量的影响试验。结果表明：不同追肥次数对烟株在大田生育期影响不明显；4次追肥的烟株农艺性状极显著高于2次追肥的烟株，烟株田间长势最好；追肥次数增加有利于烟株叶绿素含量和光合速率指标提高；从经济性状和化学成分看，4次追肥的烟株产值和产量最大，上中等烟比例较高，内在化学成分协调性较好。追肥次数的增加，有利于烟株大田生育期缩短，有利于烟株农艺性状提高，有利于烟株光合指标增大，有利于提高烟叶的产质量。

Abstract: A field experiment was carried out in Fuquan City, Guizhou Province in 2012, to study the effects of the different times of top-dressing in the same amounts of fertilizer on yield and quality of organic flue-cured tobacco. The results showed that: there was no difference of growth period in different treatments. Top-dressing four times were significantly higher than the two times in agronomic traits, and grew best. As the increase of the times of fertilizer, it was favorable to raise the chlorophyll content and net photosynthetic rate. Top-dressing four times can increase the yield, production value, average price of flue-cured tobacco and ratio of first-class tobacco leaf, and the compositions of various compounds and their proportions were found suitable. With the increase in times of top-dressing, would help shorten the field growth period of the tobacco plant, agronomic traits to improve, increased photosynthetic indicators, to improve the quality of production.
