断根、环割对烤烟叶片钾含量及产质的影响
Effects of Root-cutting and Girding on the Potassium Content,Yeild and Quality of Leaves in the Flue-cured Tobacco
摘要
Abstract
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.关键词
