摘　　要：生物炭因特殊的结构和性质,被广泛用于土壤改良。本文采用室外盆栽法,研究了稻壳生物炭老化对烤烟生长发育的影响。结果表明:施用新鲜稻壳生物炭或老化稻壳生物炭均可提高烤烟根体积和根系活力,对株高、茎围和最大叶长也有一定的促进作用,从而在一定程度上提高了烤烟的产量和质量。总体来看,以施用新鲜稻壳生物炭或15%H_(2)O_(2)氧化老化稻壳生物炭的效果较好。Due to its unique structure and properties,biochar is widely used for soil improvement.This paper used outdoor potted cultivation method to study the effect of rice husk biochar aging on the growth and development of flue-cured tobacco.The results showed that the application of fresh rice husk biochar or aged rice husk biochar could increase the root volume and root vitality of flue-cured tobacco,and also had a certain promoting effect on plant height,stem circumference and maximum leaf length,thereby improving the yield and quality of flue-cured tobacco to a certain extent.Overall,the application of fresh rice husk biochar or aged rice husk biochar oxidized by 15%H_(2)O_(2) had a better effect.
