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 the reuse of biogas slurry after fermentation of discarded fresh tobacco leaves, the effects of spraying different biogas slurry methods on the growth and development of flue-cured tobacco were tested. The experiment compares the data of 5 treatment groups sprayed with biogas slurry in different stages of flue-cured tobacco regrowth, wang long, topping, and the results show that: the waste biogas slurry of fresh tobacco leaf has no effect on the main field disease of flue-cured tobacco; The application of biogas slurry promoted the development of middle and upper leaves and the accumulation of dry matter. Compared with non-biogas slurry application, the yield of flue-cured tobacco, the proportion of superior tobacco and the average price increased, and the appearance quality of middle and upper tobacco leaves improved. Long-term spraying effect is the best, followed by Mission period, spraying effect after the top is not as obvious as the previous two periods, spraying at different times have a positive effect on the improvement of related traits.
