摘要
采用小区试验,研究了烟秆腐解物对烟草的连作障碍效应和3种修复剂的缓解效应。结果表明,烟秆腐解物对烟草生物学性状的影响不明显,但提高了烟草黑茎病的发病率。加入3种修复剂均能大大降低烟秆腐解物对烟株的自然发病率,提高烟株各项经济性状指标,其中以修复剂101效果最好。
The plot experiment was used to discuss the cropping obstacle effect of tobacco stems decomposing on tobacco straw and alleviation effects of three remediation agents.The results showed that obstacle effect of tobacco stems decomposing on tobacco straw was no significant,but increased the tobacco black shank incidence.It can greatly reduce the ratio of natural disease of tobacco plant causing by tobacco stems decomposing and improve the economical characters of tobacco plant by adding three remediation agents,especially the Remediation agent 101.
