Abstract: Flowers samples were taken from 32 red Fuji apple orchards in Qixia Shandong Province and flower nutrition diagnosis was done using Equilibrium Index method. The results showed that the optimum concentrations of N,P,K,Ca,Mg,B,Fe,Mn,Cu,Zn in Fuji apple flowers were (28. 79 ± 4. 65) g /kg,(5. 11 ± 0. 74) g /kg,(16. 24 ± 1. 02) g /kg,(84. 01 ± 20. 68) mg /kg,(43. 54 ± 9. 46 ) mg /kg,(94. 13 ± 12. 27 ) mg /kg,(109. 08 ± 38. 9 )mg /kg,(60. 25 ± 16. 7) mg /kg,(10. 09 ± 3. 15) mg /kg,(28. 31 ± 5. 06) mg /kg,respectively; The different nutrient element change ranges Fe > Cu > Mn > Ca > Mg > Zn > N > P > B > K; and there were synergistic effects or antagonistic effects in them. The orchards with Fe,Mn and Cu deficit accounted for 53. 1 %,46. 9 % and 37. 5 % of total studied orchards,respectively. All the nutrient elements were almost in the optimum dose zone and high dose zone, less in other zones,K was completely in the optimum dose zone.
