不同施肥处理对映霜红桃果实品质、产量及土壤养分状况的影响OA

The effects of different fertilization treatments on peach quality,yield,and soil nutrient status using'Yingshuanghong'peach(Prunus persica L.)as the experimental material were investigated in this study.The results demonstrated that the optimized fertilization treatment(30％chemical fertilizer reduction combined with 2,000 kg organic fertilizer)significantly enhanced peach yield,single fruit weight,vitamin C content,soluble solids content,and total phenolic content by 111.25％,53.67％,37.77％,40.91％,and 28.49％,respectively,compared to the control without fertilization.Concurrently,this treatment significantly reduced fruit hardness,fruit density,and titratable acid content by 3.12％,6.25％,and 21.88％.Compared to the control without fertilization,the treatment of replacing chemical fertilizer with organic fertilizer significantly increased soil alkali-hydrolyzable nitrogen,available phosphorus,and available potassium contents by 57.82％,399.86％,and 100.55％,respectively.These findings indicate that partial substitution of chemical fertilizers with organic amendments effectively improves peach production,enhances fruit quality parameters,and optimizes soil nutrient availability.Based on the comprehensive experimental data,the optimized fertilization strategy involving 30％chemical fertilizer reduction combined with 2,000 kg organic fertilizer application is recommended for widespread adoption in peach orchard management.
