摘　　要：[目的]探讨生物质炭与无机矿石材料组合的土壤结构改良剂对皖南烤烟生长发育、产量及产值的影响。[方法]采用田间小区试验,分析烤烟各个生育期的农艺性状、产量与产值,进行外观质量评价和烟气评吸鉴定。[结果]不同生物炭与无机矿石材料组合的改良剂可明显增加烟叶生育中后期的株高、茎粗和叶片大小、增加烟叶产量产值和上等烟叶的比例,其中X3处理(70%T20+30%ZC)增产最多,较对照处理增产398 kg/hm2,产值增加10 290元/hm2。从烟叶的外观质量评价和烟气评吸鉴定来看,所有改良剂处理均优于CK处理。[结论]施用生物炭和无机矿石改良剂是皖南地区改良植烟土壤、促进烟叶生长发育、提高产量和产值、提升烟叶品质的有效措施。[Objective] The aim was to evaluate the effects of various biochar and mineral combinations on tobacco growth,yield and profit.[Method]A field experiment was conducted. Agronomic characteristic parameters of tobacco at various stages were recorded. Tobacco leaves were identified and evaluated and total yield and profit were calculated. [Result] Compared with the control,all treatments increased tobacco height,stem and leaf. Tobacco leaf yield,high class leaf percentage and profit were increased as well. As the treatment X3（ 70% T20 ＋ 30%bamboo biochar）,the yield increased by 398 kg / hm^2,production value by 10 290 yuan/hm^2. According to the leaf appearance classification and smoke panel test,all soil amendments improved the tobacco leaf quality. [Conclusion] The use of biochar and minerals is effective and benefit to tobacco soil,growth,yield and profit at South Anhui Province.
