| 摘 要： | 通过对黑钙土上烤烟氮素积累与分配研究,结果表明,从烟株全生育期内氮素含量与积累结果可看出,不施氮肥处理,烤烟氮积累总量为96.97 kghm-2,黑钙土土壤供氮能力强;施氮处理N1(52.5 kghm-2)和N2(67.5 kghm-2)氮积累总量分别为117.94和121.59 kghm-2,烟株氮积累量同施氮量成正比,各部位烟叶氮素含量范围适中,从不同部位烟叶氮积累表明,N1和N2处理上部叶氮积累量分别为42.93 kghm-2和43.90 kghm-2,下部叶、茎花氮积累量相差不大,增加氮肥用量,烟株氮素主要集中在上部烟叶。从烤烟经济效益角度考虑,黑钙土上施氮量应控制在52.5~67.5 kghm-2之间比较适宜。

| Abstract: | Nitrogen accumulation and distribution were studied in flue-cured tobacco in chernozem.The results showed that tobacco nitrogen accumulation in the treatment N0,N1 and N2 were 96.97,117.94 and 121.59 kg hm-2.From different parts of tobacco leaves showed that the upper leaf nitrogen accumulation of the treatments N1 and N2 were 42.93 kg hm-2 and 43.90 kg hm-2,the lower leaf and flower stems were the same or less increase in the amount of nitrogen fertilizer.Nitrogen mainly concentrated in the upper leaves wi... |
