Abstract：The 18-year-old Fuji apple variety Red General was used as the material in this experiment.The effects of foliage spraying 0.2％,0.4％ or 0.6％ potassium dihydrogen phosphate on blade,fruit quality and aroma components were studied with no potassium dihydrogen phosphate as contrast.The results showed that with the increase of potassium dihydrogen phosphate concentration,the 100-blade weight,photosynthetic rate and transpiration rate increased,but the chlorophyll content had no obvious change.On the other hand,with the increase of potassium dihydrogen phosphate concentration,the average single fruit weight,soluble solid and soluble sugar showed rising trends,but the fruit firmness,contents of titratable acid and vitamin C showed no obvious change rules.In the range of this study,the kinds and contents of aroma components increased gradually with the increase of potassium dihydrogen phosphate concentration.
