为探究烤烟生产上应用生物有机肥降低化肥用量的可行性及化肥减量的适宜比例，以大理当地烤烟生产所施用的化肥常规用量为对照，研究了用等重生物有机肥代替15%、30%、45%和60%的化肥用量对烤烟生长、经济性状、内在化学成分和感官评吸质量的影响。试验结果表明，应用生物有机肥降低化肥用量30%不仅不会阻碍烤烟生长，还能在一定程度上改善烤烟经济性状，使烟叶化学成分更加协调，从而使各部位烟叶的感官评吸质量整体得到改善。其他减肥比例则会对烤烟生产带来不同程度的不良影响。研究认为，在大理州烤烟生产上应用生物有机肥降低化肥用量是可行的，且化肥减施比例为30%时较为适宜。%Field experiment was conducted to explore the feasibility of reducing chemical fertilizer rate with bio-organic fertilizer applied on tobacco production and its proper reducing proportion in Dali. The experiment included 5 treatments (0%, 15%, 30%, 45%, 60% chemical fertilizer rate reduced with equal quantities of bio-organic fertilizer). Yield, economic value, chemical component and sensory evaluation quality were measured. The results showed that the treatment of reducing 30%chemical fertilizer rate would not hinder the growth of flue-cured tobacco, and was beneficial to economic character, chemical composition, and sensory evaluation quality of tobacco leaves. The other treatments caused adverse effects in different extent on tobacco production. Therefore, it was feasible to reduce chemical fertilizer rate with bio-organic fertilizer applied on tobacco production in Dali, and the proper reducing proportion of chemical fertilizer rate is 30%.
