摘要
在对我国重要的农作物甘薯的一种害虫———马铃薯茎线虫的药用植物防治进行初探研究中,本实验共检测了9种不同药用植物:百部、鹤虱、白丑、黑丑、常春藤、穿心莲、大蒜、白芥子、苦楝皮的杀灭效果。结果表明:鹤虱对马铃薯茎线虫的杀灭效果最好,20%的鹤虱药液浸泡3h,马铃薯茎线虫基本死亡;效果次之的是百部,20%的百部浸泡5h,马铃薯茎线虫基本死亡。而对0 75%～25%浓度的鹤虱和1 5%～29%浓度的百部进行的杀灭试验表明:此2种药用植物的使用浓度和对马铃薯茎线虫的杀灭效果之间有较明显的正向量效关系。
Herb plants can be used to prevent and cure a pest to sweet potatoes: Ditylenchus dipsaci. Results of experiments with nine kinds of herb plants have shown that carpesium fruit (Carpesium abrotanoides) is the best of them to kill Ditylenchus dipsaci. After being soaked in the 20% carpesium fruit liquid for three hours, they would be dead. Next to carpesium fruit in effectiveness is stemora root (Stemona sessilifolia). It would take five hours for Ditylenchus dipsaci to become dead when they are soaked in 20% solution of stemora root. Examining the effects of carpesium fruit and stemona root in differing densities indicates that they have dose-effect relationship in killing Ditylenchus dipsaci.
