Abstract: The research results showed that the inoculation effect for C. cunninghamiana and C. glacua were better than that for C. junghuhniana, The seedlings of Casuarina withdifferent Frankia strains displayed distinct differences on the growth, ground diameter and biomass especially those which were inoculated with the three strains of 9022,9031 and 9045 increased biomass by 46%~47% after nine months in comparison to the uninoctilated seedlings.Ca,Co,P and Mg can promoted the inoculation-effects,the seedlings applied with these nutrient elements raised 26.94%~66.24% height than that of the control.The seedlings growth and nitrogen-fixing ability were limited by P. The N content in the inoculated seedlings was more than that of the uninoculated seedlings, These results demonstrate thepotential to increase the productivity of Casuarina plantation by inoculation with Frankia andby alleviation of P deficiency.
