废弃鲜烟叶产气后沼渣的不同用量对烤烟产质量的影响

为实现烤烟废弃鲜叶的最大化利用，研究了以废弃鲜叶发酵产物--沼渣作有机肥对烤烟农艺性状、抗病性、烟叶产质量的影响。结果表明：施用沼渣对烤烟田间主要病害无诱发作用，也不影响烤烟产量，但能明显促进烟叶干物质的积累，提高烤后烟叶经济性状，改善烤后烟叶内在化学成分含量比例，提升感官评吸质量；在一定用量范围内随着沼渣施用量的增加，烤烟田间农艺性状、经济性状、内在化学成分、评吸质量等指标也随之加强；尤其是沼渣施用量为150 kg/667m2的处理，各项指标均表现最优，产值比对照高383.8元/kg。

Influence of Different Application Amount of Biogas Residue from Discarded Fresh Tobacco Leaves on Yield and Quality of Tobacco

In orderto m axim ize the use ofdiscarded tobacco fresh leaves,a testw as carried outto studied the influence ofbiogas residue, ferm entation productfrom discarded fresh leaf,on the agronom ic trait,disease-resistance and the yield-quality oftobacco.The results show ed thatbiogasresidue application induced no m ain disease in the flue-cured tobacco field and had no effecton the yield.H ow ever,itsignificantly prom oted the accum ulation oftobacco dry m atter,enhanced the econom ic charactersoftobacco,im proved the proportion oftobacco chem ical com ponent,and raise sensory-sm oking quality.In addition ,w ith the increasing the am ountof biogas residue in a certain extent,the index such as the agronom ic traits, econom ic characters, internal chem ical com ponent and the sensory-sm oking quality w ere im proved. A nd especially the application am ountof 150 kg/667m 2,allthe index had good expression and there w as 383.8 yuan per kilogram higher than contrastin outputvalue.
