Abstract: To explore the influences of mineral elements formulas on yield ,the content of chlorophyll,leaf photosynthesis rates ,transpiration rates and stomatal conductance of Red Fuji apple trees was conducted in two years. Results showed that the optimal quantity offertilization of improving the content of chlorophyll was Fe 30g each tree. The optimal quantity offertilization of improving the leaf photosynthesis rates and transpiration rates were Zn 80g，Mg 50g and Ca 150g each tree. The optimal quantity offertilization of improving stomatal conductance of Red Fuji Apple Trees were Zn 40g、Mg 50g and Ca 150g each tree. The influences of B on photosynthetic characteristics of Red Fuji apple trees was insignificant.Consequently, The optimal quantity offertilization of improving photosynthetic characteristics of Red Fuji apple trees were Fe 0 g、Zn 40g、Mg 50g and Ca 150g each tree.
