The application effects of 10％,20％,30％ and 40％ of chemical fertilizers were respectively reduced under the application rate of commercial organic fertilizer 45 t/hm2 to screen out the best ratio of organic fertilizers to replace chemical fertilizers suitable for honey peach in Xinyi area.The yield and quality of juicy peaches were statistically determined,and the economic benefits and fertilizer agronomic efficiency of organic fertilizer substitution were analyzed.The analysis of economic benefits and fertilizer utilization showed that although the cost of increas-ing organic fertilizer and reducing chemical fertilizer application by 10％ and 20％ was higher than that of increasing organic fertilizer and re-ducing application by 30％ and 40％,the yield increased more and the economic benefit increased.The overall economic benefits and fertilizer agronomic efficiency were improved.The replacement of chemical fertilizers with organic fertilizers could improve fruit quality and potentially in-crease economic benefits.The treatment of replacing chemical fertilizer with organic fertilizer increased the fertilizer agronomic efficiency,and reducing the application rate by 10％ and 20％ was the best for the use efficiency of chemical fertilizer.
