Abstract: Objective]To explore bio -organic fertilizer on yield and quality of Korla Fragrant Pear through fertilization experiments.[Method]Representative tests were selected to carry out chemical fertilizer, biological organic fertilizer,chemical fertilizer and biological organic fertilizer mixed application and control treatments and then the results of experiments to explore influences of bio-organic fertilizer for Korla Fragrant Pear yield and quality were analyzed.[Result](1 )Compared with other fertilizer treatments,the highest yield of Korla Fragrant Pear was that by bio-organic fertilizer treatment.(2)On the grade of Korla Fragrant Pear, the yield of the first grade pear was the highest under the mixed fertilization of chemical fertilizer and biological organic fertilizer,which showed a very significant difference (P<0.01 ).Chemical fertilizer was the best treatment on the second grade of the pear.There was no big difference between each treatment on the yield of third grade pear and fourth grade pear.(3 )Compared to the control treatment,Korla Fragrant Pear fruit weight was improved under different fertilization treatments,and fruit shape index was affected little by differ-ent fertilizer treatments,soluble sugar content was increased to varying degrees compared with the control treatment.The soluble sugar was increased higher in bio -organic fertilizer and mixed fertilizer processing, which was increased by 15.58; and 17.75;,respectively.The titratable acid content decreased to varying degrees,with a minimum of 0.61 g /kg,and compared to the control treatment,bio-organic fertilizer and chemical fertilizer mixed fertilizer treatment process was the largest,which was decreased by 14.29;.The vi-tamin C content of fruit was increased 11.16;,15.18;,13.84;,among which,the treatment effect of bi-ological organic fertilizer was the best.[Conclusion]The application of bio-organic fertilizer can increase the yield of Korla Fragrant Pear and promote the quality of the fruit.

摘要： 【目的】研究生物有机肥对库尔勒香梨产量及品质的影响。【方法】选取代表性试验地，进行化学肥料、生物有机肥料、化肥与生物有机肥混施以及对照处理并进行分析。【结果】（1）以化肥与生物有机肥处理下产量最高，与其他施肥处理有极显著差异。（2）在库尔勒香梨等级上，一级梨的产量在化肥与生物有机肥混施处理下表现出最高产量，表现为极显著差异（P＜0.01）。在二级梨中以化学肥料处理最佳，三级梨、四级梨中各处理产量相差不大，差异性不显著。（3）不同施肥处理比对照处理中的单果质量有不同程度提高，果形指数受不同施肥处理的影响不大，可溶性糖含量均有不同程度增加，与对照处理相比，生物有机肥与混施处理中的果实可溶性糖增长较高，分别增加了15.58;和17.75;；可滴定酸的含量均有不同程度下降，其中最小值为0.61 g／kg，以生物有机肥与化学肥料混施处理最多，达到14.29;。果实中 VC 含量分别增加11.16;、15.18;、13.84;，其中以生物有机肥处理效果最好。【结论】施用生物有机肥能够提高库尔勒香梨产量，促进果实品质的改善。
