This research studied the effects of winter cropping Italian ryegrass(Lolium multiflonim L.) on the soil properties and spore density of arbuscular mycorrhizal fungi(AMF),and their influences to the growth of rice,in an Italian ryegrass-Rice Rotation(ERR) system.The differences in the physical and chemical properties and the spore density of AMF) between the farmland soil in a paddy field of ERR system and in an idled paddy field(control) were investigated.The soil used for rice cultivation was applied to three treatments:γ-ray sterilization,AMF inoculation afterγ-ray sterilization and the control.The results showed that the winter cropping Italian ryegrass had no significant effects on the soil properties,while it significantly increased the density of AMF spores in soil(p<0.01).It could also significantly improve the plant height, leaf number and tiller number of rice,while the improvement to the above-ground biomass and the rice yield were not significant(p> 0.05).The sterilization treatment clearly improved the thousand kernel weight and yield of rice.The AMF inoculation treatment promoted the thousand kernel weight the yields of rice either in the IRR or CK field.These results suggested that soil micro-organism community is an important influencing factor to rice yield,and AMF has a positive effect on the growth of rice.Winter cropping ryegrass could increase the density of AMF spore and improve the soil micro-organism community structure,thus promoting the growth of rice.
