吉林省人参根际土壤真菌群落生态特征及区系分析

Analysis of Ecological Characteristics and Classification of Fungi Community in Rhizosphere Soil of Ginseng in Jilin Province

针对吉林省主要人参产区延边朝鲜族自治州、白山市和通化市3个地区的125份人参根际土壤进行了土壤真菌分离、鉴定和区系分析。试验共分离鉴定土壤真菌16个属,其中鉴定到种的有12个属。分析结果表明:延边、白山市和通化市的真菌种类分布有所不同,其群落生态特征有所差异。延边和白山市的群落组成结构相似,两地的真菌种类多于通化市;而通化市土壤中真菌种类分布均匀度高,群落较稳定。分析认为这与3个地区的气候条件和其他生态影响因素有直接关系。

Fungi in 125 soil samples collected from three main ginseng production areas in Jilin province were separated and identified in 2006. Sixteen genera are isolated and identified, but two genera are unidentified. It was discovered that there＇s difference between the region Ⅰ,Ⅱ and Ⅲ for the fungus＇ species and distribution. And the ecological characteristics of the fungi were not completely consistent. Richness index of region Ⅰ and Ⅱ was high, but evenness degree index of region m is high. That＇s because of the impact of climatic or other reasons.
