Abstract:
Infection rate of arbuscular mycorrhizal fungi in Setaria viridis and Artemisia scoparia collected from the Fifth,Jiulong and Wutongzhuang of Fengfeng coal mining areas were detected.And the contents of Pb,Cu,Zn,Cr and Mn in plants and soil were studied using flameatomic absorption spectrophotometry,respectively.The absorption and accumulation of two plans with five kinds of heavy metal in the three mining area also were compared by calculating transfer coefficient and enrichment coefficient.In order to provide theoretical support for using plant-arbuscular mycorrhizal fungi to repair soil heavy metal pollution.The results showed that the infection rates of mycorrhiza with S.viridis and A.scoparia were the highest in Wutongzhuang mine,reaching 86.667% and 49.033% respectively.Under natural conditions,they could form a good symbiotic relationship with arbuscular mycorrhizal fungi.The accumulation of Pb and Zn of S.viridis in Wutongzhuang mine were better,the aboveground Pb content,underground Pb content,transfer coefficient and enrichment coefficient of S.viridis were reached 24.157 mg·kg-1,19.139 mg·kg-1,1.262,and 0.156.And Zn content of the aboveground,transfer coefficient and enrichment coefficient were reached 42.295 mg·kg-1,1.127,and 0.259.Not only it was higher than S.viridis in the Fifth and Jiulong mine,but it was also higher than A.scoparia.The accumulation of Cr was higher in both of them than in other mining areas,andthis metricof S.viridis in the same mining area was also higher than that of S.viridis.For the accumulation of Cu and Mn,two kinds of plants in different mining areas showed inconsistent performance,which indicated that the absorption and accumulation of heavy metals by different plants were different.
