This paper dealed with the effects of P fertilization and ectomycorrhizal fungal inoculation on productivity and nutrient accumulation of Eucalyptus globulus plantation in Chuxiong, Yunnan. The results showed that ectomycorrhizal fungal inoculation increased tree growth of E . globulus in early stage of the plantations. However, the effect of ectomycorrhizal fungal treatments was no significant three years after plantation establishment. P fertilization increased tree diameter and height growth. But the effect of P treatments was not significant at 4.5 years old. P fertilization increased survival rate of planted trees. The low survival rate in low P treatments could increase tree growth in late stage of the plantation. The insignificant effect of P treatments at 4.5 years old was partly due to the change of survival rate in different P treatments. P fertilization increased N, P and K accummulation in tree biomass and nutrient use efficiency in wood and biomass production. P fertilization increased P accumulation in understorey and litter, but N and K. Leaf and soil sample analysis further proved that P fertilization promoted tree growth in the early stage. The experimental results indicated that ectomycorrhizal fungal inoculation could only increase tree growth in low P treatments instead of high P treatments.
