摘　　要：老龄苹果园由于长期定植而出现树势下降,微生物肥料可以通过改善果园土壤的生态环境而改善果树生产力。本研究通过在陕西洛川县老龄红富士苹果园设置肥效对比试验,探讨施用微生物复混肥与氮磷钾复合肥对老龄园红富士苹果产量及品质的影响。结果表明:与施用无机肥的对照组相比,施用微生物肥料的处理组各项指标均有提高。其中产量增幅为8.45%~22.86%,平均增长率16.71%;单果重平均234.96g,提高12.02%;优果率平均68.54%,提高15.76%;糖度平均15.90°,提高3.05%;硬度平均12.57 kg/cm^2,提高2.86%。说明施用微生物肥料对老龄苹果园的产量和品质均有良好效果。The productivity of apple trees in old orchards decline because of long-term planting,while the microbial fertilizer can improve the productivity of fruit trees by improving the ecological environment of the orchard soil.The contrast test was carried out between the traditional fertilizer and microbial fertilizer in old apple orchards of Luochuan County,Shaanxi Province in this study,and the yield and quality of apple were evaluated between the two treatments.The results showed that all indicators were improved in the microbial fertilizer treatment compared with the control.The increase range of yield was 8.45%~22.86%,with an average growth rate of 16.71%;the average fruit weight was 234.96 g,which increased by 12.02%;the average optimal fruit rate was 68.54%,which increased by 15.76%;the average sugar degree was 15.90°,which increased by 3.05%;the average hardness was 12.57 kg/cm^2,which increased by 2.86%.This study validated that the microbial fertilizer had a significant effect on the improvement of yield and quality of apple.
