Abstract：Using 13-year-old Hwangkumbae pear trees as materials,the effects of woody peat organic fertilizers (including woody peat,potassium humate,microbial organic fertilizer and soil conditioner) combined application with compost manure on single fruit weight,fruit firmness,soluble solids,carbohydrate and organic acid content,and flavor index were investigated.Compared with the treatment of applying compost manure only,the treatments of compost manure + woody peat,compost manure + potassium humate,compost manure + microbial organic fertilizer and compost manure + soil conditioner all had no significant effects on single fruit weight and yield,but improved the soluble solids content.The treatments of woody peat organic fertilizers significantly increased the contents of carbohydrate and each component,the treatments of compost manure + potassium humate,compost manure + microbial organic fertilizer acquired the highest content.All these treatments showed no obvious effects on organic acids and each component.Moreover,the treatments of woody peat organic ferlitizer could enhance the fruit flavor significantly,and the largest flavor index was observed under the treatment of compost manure + microbial organic fertilizer.Considering from the fruit soluble solids,carbohydrate and acid content and flavor index in this experiment,applying compost manure 7.5 t/hm2 + microbial organic fertilizer 3.9 t/hm2 was the optimal treatment for Hwangkumbae pear.
