摘要 为了给优质高香气烟叶生产提供技术支撑,田间试验以烤烟(Nicotiana tobacumL.)品种云烟87为试材,于2005-2006年在河南南阳研究了成垄方式和施钾方法对烤烟氨基酸含量的影响。结果表明:培土成垄和分次施钾可以使烟叶中氨基酸总量增加,各处理烟叶中天冬氨酸、苏氨酸、丝氨酸、苯丙氨酸、酪氨酸、精氨酸等含量均较对照有很大提高,以低起垄二次培土成垄,钾肥2次追施处理最高,氨基酸质总量达到了57.40 mg/g。钾肥施用次数相同,低起垄培土成垄处理的氨基酸含量高于平栽培土成垄的处理;成垄方式相同,钾肥追施2次对氨基酸总量的影响大于钾肥作基肥1次施入。 To provide technical support for producing high quality and experiment was conducted during 2005 - 2006 to study the relationship aroma tobacco leaves, a field between the contents of ami- no acid and ridge-forming, potassium fertilizing methods by using a tobacco (Nicotiana tobacum L. ) cultivar yunyan 87 in Nanyang. Results showed that: (1) ridges formed by piling up soil after planting and potassium fertilization by stages can increase the total amount of amino acid. Compared with the common cultivation, the contents of Asp, Thr, Ser, Phe, Tyr, Arg etc were greatly increased in all treated samples. For the low ridges formed by double pilings, potassium fertilizer topdressed two times was the highest, totaling 57.40 mg/g. (2) by using the same potassium fertilizing methods, the total contents of amino acid treated with low ridges formed by piling up soil was higher than ridges formed by piling up soil after flat planting; with the same ridge forming methods, the total contents of amino acid treated with potassium fertilizer two times was higher than when potassium fertilizer was applied only once.
