摘 要：为探索烟秆有机肥（发酵烟秆+芝麻饼肥+腐植酸）对烤烟根系发育、烟叶矿质营养和烟叶质量的影响,采用盆栽试验设置不同用量烟秆有机肥处理,研究其对烤烟根系发育和矿质元素的影响.结果表明,施用烟秆有机肥对烤烟根系生物量和生理活性提高作用较大,在旺长期和圆顶期促进作用最明显,表现为根体积增长率、根干重增长率、根系活力及根系吸收面积在此时期出现高峰,以添加500 g/盆的处理效果最好,其根体积、根干重、根系活力和根系总吸收面积于移栽后75 d分别比对照提高了60.77%、114.76%、53.12%和148.36%；烟秆有机肥配施促进烤烟对矿质元素的吸收,特别是对磷、锌、铁、锰含量提高效应较显著.综合考虑,添加烟秆有机肥500 g/盆的处理最佳,为培育烟株健壮根系,均衡烤烟矿质营养及烟秆的还田应用提供参考.

Abstract： To explore the effects of a tobacco stem organic fertilizer combined with other organic fertilizers on tobacco root system, mineral nutrients and tobacco leaf quality, a pot experiment was conducted with different amount of tobacco stems mixed with organic fertilizers. The tobacco stem mixed organic fertilizers used were tobacco stem organic fertilizer, sesame cake and humic acids. The results showed that tobacco the stem organic fertilizer combined with organic fertilizers could significantly promote the root biomass and root physiological activities, especially at the vigorously growing stage and the toping stage. The volume growing rate, dry weight growing rate, root activity and root active absorb area all appeared peak during this stage. At later stages of development tobacco stems combined with organic fertilizers could slow down the senescence of root system. The 500 g/pot treatment had the best effect with its root volume, root dry weight, root vigor and root absorb total area increased by 60.77%, 114.76%, 53.12% and 148.36% compared with control, respectively. The study also revealed that tobacco stems combined with organic fertilizers played a positive role in promoting mineral contents of flue-cured tobacco. Tobacco stems combined with organic fertilizers enhanced absorption of mineral elements, especially P, Zn, Fe, and Mn. Application of tobacco stems mixed organic fertilizers with 500 g/pot was therefore the optimum treatment. This provides theory gist for cultivating strong tobacco root system, balancing the mineral nutrients of flue-cured tobacco and for the decomposition application of tobacco stem organic fertilizers.
