为了探明不同生物炭用量与氮肥配施对烤烟生长及烟叶主要化学成分的影响,以云烟87为试材,通过田间小区试验研究了9种不同的生物炭与氮肥配施比例对烤烟生长及烟叶主要化学成分的影响。结果表明:生物炭与氮肥配施能够调控烤烟的生长,促进烟株的生长发育,加快出叶速度,但施炭量与对烤烟生长的促进作用不呈正相关,当施炭量超过3 750 kg/hm~2、施氮量超过112.5 kg/hm~2时对烤烟生长的促进作用逐渐下降。生物炭与氮肥配施能够在一定程度上促进根系的发育,提高烤烟干物质积累量。生物炭与氮肥配施能够调节烤后烟叶的总糖与还原糖含量至最适范围内,降低烟叶淀粉含量,提高烟叶钾含量,有利于提高烟叶燃烧...

In order to study the effects of different amount of biochar application combined with nitrogen fertil-izer on the growth of flue-cured tobacco and the main chemical composition of tobacco leaves.Yunyan 87 was select-ed as testing material and a field experiment was designed to study the effects of nine different amount of biochar application combined with nitrogen fertilizer on the growth of flue-cured tobacco and the main chemical composition of tobacco leaves.The results showed that biochar application combined with nitrogen fertilizer could regulate and promote the growth of flue-cured tob...
