摘  要：
采用大田试验,对烤烟进行断根、环割和断根+环割处理,考察烟叶片的钾含量、经济学性状以及主要化学成分。结果表明,断根、环割和断根+环割处理提高了不同部位烟叶钾含量,与对照相比,上部叶钾含量分别提高了45.58%、20.00%、9.77%,中部叶分别提高了33.86%、33.33%、49.47%,下部叶分别提高了146.07%、198.31%、167.42%。断根、环割和断根+环割处理,烟叶产量分别比对照提高17.00%、20.08%、9.42%;烟叶的均价显著高于对照,分别提高42.69%、70.13%、53.25%;烟叶的产植极显著高于对照,分别提高104.28%、67.69%、66.95%。断根、环割、断根+环割处理均可以改善烤烟烟叶中主要化学成分的协调性,其中,断根+环割处理的效果最好。断根、环割、断根+环割对烤烟的上等烟、中上等烟比例的影响不明显。

摘  要：
Field experiment was conducted to study the potassium content,ecologicol trait and main chemical composition root-cutting and girding.The result showed that,the effects of improving the potassium content of different position's leaves was significant by the root-cutting,girding and root-cutting and girding treatments,compared with the CK,the potassium content of uppre leaves was increased by 45.58%,20.00%,9.77% respectively,middle leaves was increased by 33.86%,33.33%,49.47%,146.07%,lower leaves was increased by 198.31%,167.42%.Root-crtting,girding and root-crtting combined with and girding treatments,the yeild was increased by 17.00%,20.08%,9.42% respectivdly compared with the CK,the average price was increased by 42.69%,70.13%,53.25% respectively and the effects were significant compared with the CK,yeild values was increased by 104.28%,67.69%,66.95% respectively compared with the CK.Root-cutting,girding and root-cutting and girding treatments increased the yeild of the flue-cured tobacco at different degree,and increased the average price and output value remarkably.Root-cutting girding and root-cutting and girding treatments improved the coordination of the main chemical composition,and the effect of root-cutting and girding treatment was the best.Root-cutting,girding and root-cutting and girding treatments had no significant effects on the high grade and mid-high grade leaves.
