【摘要】 本试验以K326为供试品种,试验设3个因素,每个因素设两个水平,共8个处理,随机区组排列,重复3次。结果表明:处理为施氮量135kg·hm-2、单株留叶数20片、喷施α-NAA(10mg/L)的烟叶产量、产值、均价、上等烟比例、上中等烟比例最高,各部位烟叶的烟碱含量适中。更多还原

【Abstract】 The experiment was conducted to study K326,a variety of flue-cured tobacco with three factors, each factor included two different level. Thus,there were eight different treatments. They were arranged at random and repeated three times. The results showed that the yield,output value, average price,high-quality ratio and high-middle-quality ratio of the treatment which applied pure nitrogen 135 kg·hm -2 ,20 leaves remained per plant and sprinkled α-NAA(10 mg/L)were highest; nicotine contentsand other chemical contents were moderate in all parts.更多还原
