Abstract: |
Soil samples under the canopy of nine medicinal plant species from Anguo city of Hebei province were collected and examined.Nine species of medicinal plants were infected with AM fungi but the infection rates changed with different medicinal plants.Among nine species 44.5% medicinal plants are Arum-type 55.5% are Paris-type.Soil available N was positively correlated with spore density of Salv ia miltiorrhiz a and Dioscorea opposite and hyphal and total percent colonization of A denophora borealis while negatively correlated with arbuscular colonization of Aster tataricus;Soil available P exhibited a positive correlation with arbuscular colonization of Salv ia miltiorrhiz a and vesicular colonization of Dioscorea opposite while a negative correlation with spore density of Platycodon grandif lorus and vesicular colonization of Atractylodes macrocephala; Spore density of Bupleurum chinense had a positive affection with soil organic matter;Soil pH was negatively correlated with hyphal and total colonization of A denophora borealis and spore density of Bupleurum chinense while positively correlated with spore density of A denophora borealis. |
