摘　　要：为生产上大面积推广应用竹醋液复配剂提供理论依据,采用随机区组试验,研究竹醋液与菌核净复配剂对烟株大田生长及烟草赤星病防治的影响。结果表明:复配剂对烟株大田生长发育与清水处理无明显差异,但可增加烤后烟叶总糖、还原糖和钾的含量,平均较清水处理增加3.47%、4.28%、15.96%;减少氯的含量,平均较清水处理减少11.11%;复配剂对烟草赤星病的田间防效与菌核净差异不明显,但农药残留量显著降低,平均较菌核净处理下降3.88倍。施用复配剂能够在不影响烟株田间外观表现前提下达到防治烟草赤星病且减少农药残留的效果。The effects of compounded agent of bamboo vinegar and Dimethachlon on tobacco growth and control of tobacco brown spot are studied by arandomized block experiment to provide the theoretical basis for large-area popularization and application of bamboo vinegar compounded agent in production.Result:There is no obvious difference in growing development of tobacco between compounded agent treatment and water treatment.The total sugar,reducing sugar and K content in flue-cured tobacco applied with compounded agent is 3.47%,4.28%and 15.96%higher than that of water treatment.The Cl content in flue-cured tobacco applied with compounded agent is 11.11%lower than that of water treatment.There is no obvious difference in field efficacy of tobacco brown spot between compounded agent treatment and Dimethachlon treatment,but pesticide residue decreases significantly.The pesticide residue under compounded agent treatment is 3.88 times lower than that of Dimethachlon treatment averagely.In conclusion,applying compounded agent can realize the effect of controlling tobacco brown spot and reducing pesticide residue on the premise of not affecting tobacco appearance performance in field.
