Effects of Three Mycorrhizal fungi Inoculated on Container Seedlings of Quercus variabilis

The mycorrhizal fungi technology has the vital significance in the breeding of high quality seedlings.In this experiment,three mycorrhizal fungi were used to treat the rhizosphere soil of Quercus variabilis seedlings and to study the infection ability of mycorrhizal fungi and its effects on the growth of Quercus variabilis seedlings.The results showed that mycorrhizal fungi could greatly accelerate the growth of height,basal diameter,dry biomass and lateral roots of Quercus variabilis seedlings.The net Photosynthesis rate and chlorophyll of the seedlings were also increased by the mycorrhizal fungi treatments.Meanwhile the excellent fungi strains of Cortinarius sublanatus were selected in Beijing.
