Abstract:
Zoysia japonica cv.‘Lanyin No.Ⅲ’ was used as material,five different rootzone compositions were designed，namely P，85% sand+15% peat；Z，85% sand+15% zeolite；M，85% sand+7.5% zeolite+7.5% peat；T5，absorbent polymers component laid at a depth of 5 cm；T10，absorbent polymers component laid at a depth of 5 cm respectively to study effects of rootzone composition on root-invading fungi incidence.Morphological and molecular methods were used to identify the fungal isolates.The results showed that 14 fungal species were isolated and identified from the root.Rhizoctonia sp.and Fusarium oxysporum were the most common fungal species in all rootzone composition，and were the potential pathogenic fungi that might cause turf diseases.Root-invading fungi and their incidence showed a significant difference under rootzones.The lower incidence of fungi were found in T5 and T10，and the higher incidence of fungi were found in M and Z.The rootzone mixed with zeolite significantly increase root-invading fungi incidence and species of Zoysiagrass.The above founding could suggest that it was necessary to consider reducing the use of zeolite in turf establishment.
