In order to determine the best fertilization amount on kiwifruit，it is necessary to explore the effects of different fertilization rates on the yield and quality of kiwifruit and analyze the effects of fertilization rates on the contents of nitrogen，phosphorus and potassium in kiwifruit.“Hongyang” kiwifruit was taken as the research object.Compound fertilizers of 0 kg/plant (control)，0.25，0.5，0.75，1 kg/plant were applied at one time at the germination stage of kiwifruit to study the effects of different fertilization amount on the yield，quality (including soluble solids，soluble total sugar，titratable acid，soluble protein，vitamin C)and nitrogen，phosphorus and potassium contents of “Hongyang” kiwifruit.The results showed that:(1)Fertilization effectively increased the average transverse and longitudinal diameters of kiwifruit，and the difference of average transverse and longitudinal diameters between fertilization amount of 0.75，1 kg/plant and control reached a significant level；Different fertilization amount improved the average fruit weight of kiwifruit，which was increased by 15.10%，12.55%，27.21% and 13.08%，respectively，compared with the control，and the fertilization amount of 0.75 kg/plant among them was significantly different from the control.(2)Fertilization increased the content of soluble solids，vitamin C and soluble total sugar in kiwifruit.Compared with the control，the fertilization amount of 1 kg/plant fruit soluble solids was significantly different.The content of vitamin C in 0.5 kg/plant fruit was the highest，reaching 145.29 mg/100 g. The contents of titratable acid and soluble total sugar were 1.18% and 6.04%，respectively，at the fertilization amount of 0.75 kg/plant，which were higher than other treatments.(3)During the whole growth period，the dry matter content of kiwifruit generally showed an “S”-shaped increasing trend，and the contents of nitrogen，phosphorus and potassium in leaves and fruits showed an “increasing-decreasing” trend with the increase of fertilizer application.(4)During the whole growth period，the order of nitrogen content in each organ was:leaves>fruits，in which the nitrogen content in leaves showed an “upward-downward” trend，and the nitrogen content in fruits generally showed a descending trend. The order of phosphorus content in each organ was:leaves>fruits，the phosphorus content in leaves generally showed a “downward-upward-downward” trend，and the phosphorus content in fruits generally showed a downward trend.The potassium content of leaves showed a fluctuating downward trend，and the potassium content of fruits generally showed a “downward-upward” trend.To sum up，fertilization increased the average single fruit weight，soluble solids，vitamin C and soluble total sugar content of kiwifruit in different degrees，and improved the nutritional quality of kiwifruit.The best comprehensive effect was fertilization rate of 0.75 kg/plant.During the whole growth period，the dry matter content of fruit showed an “S”-shaped upward trend，and the nitrogen and phosphorus content of each organ was as follows:leaves>fruits，the potassium content of leaves showed a fluctuating downward trend，and the potassium content of fruits generally showed a “downward-upward” trend.
