| 摘 要： | 采用小区试验,研究了根系分泌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,根系分泌物对烟草的连作障碍效应非常明显,表现在抑制烟草的生长发育,增加烟草黑胫病发病率.加入3种修复剂均能大大降低根系分泌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.

| Abstract: | A plot experiment was made to investigate the obstacle effect of root exudates on the soil in continuous tobacco cropping and the alleviation effects of three remediation agents.The results showed that obstacle effect of root exudates was very obvious,the growth of tobacco was inhibited and the incidence of tobacco black stem disease increased.All the remediation agents used greatly reduced the natural incidence of diseases of the tobacco plants and improved their economical characters.Remediation agent 101... |
