Abstract:
To investigate the correlation of soil physicochemical properties and arbuscular mycorrhizal fungi（AMF）of Medicago sativa L.grassland in the mining area of Datong city,Shanxi Province,we sampled rhizome and rhizosphere soil of Medicago sativa L. distributed in different soil layer of four sample plots(Hunyuan county,Nanjiao district,Datong county and the mining area)in October,2014,and analyzed the physiochemical properties of rhizosphere and the colonization rate of AMF.The results showed that the colonization rates of AMF with all above 70% and spore density decreased with the increasing of soil depth in all sample plots except Datong county.The colonization rate of AMF significantly and positively correlated with organic mater,NO3--N,AP,EGG and TEG(P<0.05).Moreover,TEG and EEG performed very significantly positive correlation with the colonization rate,organic matter,NO3--N and AP(P<0.01).Significant correlation of colonization rate and NO3--N,AP,AK and EEG(P<0.05)only showed in the soil layer of 20-30 cm depth through analyzing total correlatings.What was more,the spore density acted in the same way with the colonization rate.These experimental results indicated that AMF could build a good symbiotic relationship with Medicago sativa L.and played an important role in soil nutrients,especially in the soil layer of 20-30 cm depth.
