摘　　要：采用菌根应用技术,对药用植物白芷的VA菌根进行了分离鉴定,并采用AMF孢子接种白芷,观察VA真菌对白芷生长效应的影响。结果表明:泡囊成群分布,白芷根系AMF真菌菌丝感染率为44.0%、丛枝感染率为17.5%;从白芷根际土壤分离到摩西球囊霉和隐球囊霉菌根真菌,土壤含孢量为11.3个/g;孢子接种量不同,白芷生长效应存在差异,白芷对VA菌根真菌存在依赖性,接种一定数量的AMF真菌可显著提高白芷的产量。The mycorrhiza application technology was adopted to study the vesicular arbuscular mycorrhiza（VAM） of Angelica dahurica,moreover,inoculation of AMF spore into Angelica dahurica to observe the influence of VA on growth effect of Angelica dahurica.The results showed that there were groups of vesicle around roots of Angelica dahurica;the AMF mycelial infection rate and arbuscular infection rate of Angelica dahurica roots were 44.0% and 17.5%,respectively.The Glomus mosseae and the Glomus occulumr were separated from rhizosphere soil of Angelica dahurica,and the spore content in soil was 11.3 spores/g.If the vaccination quantity of AM fungi was different,the growth effect of Angelica dahurica showed differences.Therefore,Angelica dahurica is dependent on VAM fungi.
