| 摘 要： | 通过大田试验，研究了不同氮素形态及配比对烤烟叶片中谷酰胺合成酶(GS)、蔗糖合成酶(SS)、蔗糖磷酸合成酶(SPS)活性及烟碱、还原糖含量的影响、结果表明，在移栽后85d至采收结束，T2(纯施NH4-N)烟叶中的GS和SPS-直保持相对较高的水平；在移栽后91d，其烟碱含量是T1(纯施NO3-N)的1．2倍、13(NO3-N：NH4-N的质量比为1：1)的1．1倍．还原糖含量是T1的0．4倍、13的0．6倍、T1有利于还原糖的积累；T3有利于碳氮代谢的协调进行、

| Abstract: | A study was conducted on the effect of different nitrogen forms on the activity of GS,SS,SPS and content of nicotine and reduced carbohydrate in flue_cured tobacco leaves through filed experiment.The result showed that GS of T2 remained a relatively high level from 85 d after transplanting to the end.The content of nicotine was 1.2 times that of T1,1.1times that of T3 on 91 d after transplanting,the content of reduced carbohydrate was 0.4 times that of T1,0.6 times that of T3. T1 was more suitable for the accumulation of reduced carbohydrate ;T3 was more suitable for the harmonization of carbon_nitrogen metabolism. |
