摘要
打破了传统的化学药剂(特别是农药)防治黄芪根腐病菌的局限,以发展绿色防治中药材病害为前提,采用蛇床子、知母的提取液制备含药培养基,并以灭菌水作为对照,分别接种黄芪根腐病菌,探讨这两种中药对黄芪根腐病菌—尖孢镰刀菌(Fusarium oxysporum)的抑制作用。研究结果表明,2种中药提取物对抑制黄芪根腐病菌均有不同程度的影响,实验结果表明,无论从药剂类型还是药剂浓度来看,蛇床子防治黄芪根腐病菌的效果最佳,具有显著水平,其最高抑制率为96.13%。
This objectives of the present study are to break the limitations in preventing and controlling Astragalus root rot fungus by chemical agents（especially pesticides） and to develop green measures in preventing and controlling diseases of Chinese herbal medicines.Using Fructus cnidii,Rhizoma anemarrhenae extracts drug-containing medium,and sterile water as control,after inoculating with Astragalus root rot fungus,the inhibitory effects of these two kinds of traditional Chinese medicine on Astragalus root rot fungus-Fusarium oxysporum were studied in vivo.The results showed that kinds of traditional Chinese medicine extracts exhibited different impacts in inhibiting Astragalus root rot fungi.Analysis of variance results indicated that from the point of view of both the types and concentrations of extracts of two Chinese medicines,F.cnidii showed better performance in preventing and controlling Astragalus root rot fungi,Cnidium combat the effect of Astragalus root rot fungus is more obvious,with significant level,the highest inhibition rate 96.13%.
