摘 要:为探索有机烟叶生产的合理施氮量和密度,2009年在凤冈县进化镇进行了不同密度、施氮量对有机烟叶产量、质量的影响试验。结果表明:1)不同密度、施氮量对有机烟叶大田生育期影响不明显;2)在施氮量82.5 kg/hm^2、种植密度18 000株/hm^2条件下,烟叶田间长势良好,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,产值和产量最大。Field experiment was conducted to investigate the effects of planting density and amounts of nitrogen application on the yield and quality of tobacco leaves by organic cultivation at Jinhua town in Fenggang county in 2009. The experiment results indicated that ( 1 ) different densities and nitrogen applications had no significant effect on the organic tobacco dur- ing the growing period. (2) The output value and yield of tobacco leaves with nitrogen application of 82. 5 kg/hm2 were the highest. The planting density of 18000 plants for each hectare for tobacco obtained better growth, high rate of superior leaf, high rate of orange leaf and good coordination of intrinsic chemical compositions.
