Abstract: Five-year-old Korla fragrant pear was used as test material,and ten different fertilization treatments including biological bacteria fertilizer,urea,potassium phosphate fertilizer,sheep manure and foliar fertilizer were used to study the effects of different fertilization treatments on the fruit yield and quality of Korla fragrant pear,in order to provide reference basis for simplified fertilizationtechnology of Korla fragrant pear.The results showed that under different fertilization treatments,S7 treatment had the best effects on single fruit weight and internal quality of Korla fragrant pear when the application rates of biological bacterial fertilizer 900 kg·hm-2,urea 150 kg·hm-2,potassium phosphate fertilizer 600 kg·hm-2,sheep manure 3 750 kg·hm-2 and foliar fertilizer 2.25 kg·hm-2;common fertilization（S9 treatment）in orchard had the best effect on stone cell content and yield per plant.
