| 摘 要： | 为探索有机烟叶生产的合理施氮量和密度,于2009年在凤冈县进化镇进行了不同密度及施氮量对有机烟叶产质量的影响试验。结果表明:1)不同密度及施氮量对有机烟叶大田生育期影响不明显。2)施氮量82.5kg/hm2、种植密度18 000株/hm2能获得最大的产值和产量,且田间长势、上等烟率、上中等烟率、橘黄烟率和内在化学成分协调性较好。3)综合表现最好的是施氮量82.5kg/hm2、种植密度18 000株/hm2的处理,其次是施氮量67.5kg/hm2、种植密度18 000株/hm2的处理。

| Abstract: | K326(a tobacco variety) was tested under different planting density and nitrogen application level to study the effects on yield and quality of organic tobacco and probe the rational planting density and nitrogen application level for production of organic tobacco in Fenggang County,Guizhou.The results showed that: 1) Different planting density and nitrogen application level had no significant effect on different growth stage of K326.2) The maximum output value,highest yield and good interior chemical compo... |
