微生物有机无机复混肥对陕北苹果产量及品质的影响

通过在陕西渭北旱塬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施用传统肥料对红富士苹果产量、品质的影响。结果表明：施用微生物研究所研制的苹果专用微生物复混肥后，产量与对照相比均有提高，最高增长幅度为28.82%，最低为3.06%；单果重平均为233.88 g，平均提高15.83%；商品果率平均为80.80%，平均提高8.67%；糖度平均为13.52%，平均提高4.79%；硬度平均为9.61 kg/cm2，平均提高3.58%。说明施用微生物复混肥在提高产量尧改善苹果品质方面效果显著。

Effects of a microbial organic-inorganic compound fertilizer on yield and quality of fuji apple in Weibei dry plateau

By selecting apple orchards, we conducted comparative experiments to evaluate the effects of a microbial organic -inorganic compound fertilizer (experiment group) and conventional inorganic fertilizer (control group) on the the yield and quality of Fuji apple cultivated in Weibei dry plateau. The results showed that the microbial organic-inorganic compound fertilizer developed by Shaanxi Institute of Microbiology increased yield per 667 m2 of Fuji apple, the increasement of yield ranged from 3.06% to 28.82%. Average weight was 233.88 g per apple, increased by 15.83%. Average commodity fruit rate was 80.80% with 8.67% increasement. Average saccharine degree was 13.52% with 4.79% increasement, and average firmness was 9.61 kg/cm2 with 3.58% increasement. This study validated that the microbial organic-inorganic compound fertilizer had a significant effect on improvement of yield and quality of Fuji apple.
