摘要: 为探讨大蒜根系腐解物对烟草黑胫病菌的防治效果,采用控制条件室内培养方法,研究不同腐解时间的大蒜根系腐解液对烟草黑胫病菌的抑制作用。结果表明,不同腐解时间的大蒜根系腐解液均能在一定程度上抑制烟草黑胫病菌菌丝生长,其中腐解15 d的大蒜根系腐解液抑制效果最好。腐解15 d的大蒜根系腐解液处理后的菌丝出现原生质泄漏、菌丝分支及菌丝变形等现象。盆栽试验表明,添加不同腐解时间的大蒜根系腐解液在烤烟移栽后第9天对烟草黑胫病的防治效果为4.30%~41.38%。由此推论,大蒜根系腐解液对烟草黑胫病菌具有较好的抑制作用,对烟草黑胫病有较好的防治效果。

Abstract: In order to study the effect of garlic root decomposition on tobacco black shank in tobacco growing soil,the greenhouse pot experiment was carried out to study inhibition effects on tobacco black shank through indoor cultivation by garlic root decomposition with different decomposing time.The experimental result indicated that garlic root decomposition with different decomposing time could inhibit the growth of tobacco black shank fungus,and garlic root decomposition that decomposed 15 days had the best inhibition effect.Treated by garlic root decomposition that decomposed 15 days,myceliun appeared hyphae deformation,hyphae branch and protoplasm leak.Pot experiments showed that the control effect of garlic decomposition solutions decomposed in different times on tobacco black shank was to 4.30%-41.38% in ninth days after the transplanting of flue-cured tobacco.From the findings it is inferred that garlic root decomposition had a good inhibitory effect on tobacco black shank,and had highly activity on tobacco black shank.

Key words: Garlic, Root decomposition, Tobacco black shank, Mycelial growth rate
