摘　　要：为探索废弃鲜烟叶发酵后沼液的再利用方式,开展了沼液不同叶面喷施方法对烤烟生长发育的影响的试验。试验分别对比了在烤烟团棵、旺长、打顶后不同时期喷施沼液的5个处理组的数据,结果表明:废弃鲜烟叶发酵沼液对烤烟主要田间病害无诱发或传播作用;喷施沼液对中上部叶片发育和干物质积累有促进作用,与不喷施沼液相比,烤烟产量、上等烟比例、均价有所提高,中上部烟叶外观质量有所改善;以旺长期喷施效果最好,其次是团棵期,打顶后喷施效果不如前两个时期明显,不同时期多次喷施对相关性状的改善有正向作用。In order to explore re-use of biogas slurry from fermentation of fresh flue cured tobacco leaves, this paper studied the influence of biogas slurry spraying methods on growth and development of flue-cured tobacco. Test were compared in the rosette stage, faster growing stage, topping in different period after spraying biogas slurry of five treatment groups of data, the results showed that： the fresh leaf of flue-cured tobacco waste biogas slurry did not induce or propagate tobacco field disease; spraying biogas slurry could promote development of upper leaves and increase dry matter accumulation. Compared to CK, tobacco yield, superior tobacco proportion and average price, and middle and upper leaves appearance quality were improved by spraying. Spraying in faster growing stage has the best effect, followed by that in rosette stage, then after multi-topping, repeatedly spraying on the related traits in different periods had positive effect.
