[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 research aimed to discuss the effect of soil structure improver combined with biogenic carbon and inorganic ores on the growth, yield and output value of south Anhui flue-cured tobacco. [Method] With field plot experiment, the agronomic traits, yield and output of flue-cured tobacco during different growth stages were analyzed, and the appearance quality and flue gas aspiration were identified. [Result] The results showed that the combination of different biochar and inorganic ores could significantly increase plant height, stem diameter and leaf size of middle and late tobacco leaves, and increase the yield and yield of top tobacco leaves. Among them, X3 treatment (70% T20 + 30% ZC) increased the yield to 398 kg / hm2 and increased the output value by 10 290 yuan / hm2 compared with the control. From the appearance of tobacco quality evaluation and identification of flue gas suction point of view, all improvers were better than CK treatment. [Conclusion] The application of biochar and inorganic ores improver is an effective measure to improve the tobacco planting soil, promote the growth and development of tobacco leaves, increase the yield and output, and improve the quality of tobacco in southern Anhui.
