摘　　要：为探明液体有机肥对冰糖橙土壤肥力及果实品质的影响,设置不施有机肥(CK)、常规有机肥(CF,固体)、YHY液体有机肥(T1)、YLG液体有机肥(T2)4个处理,研究不同处理对土壤肥力和果实品质的影响。结果表明:与CK相比,施用液体有机肥均能不同程度地提升土壤中的有机质、碱解氮、有效磷和速效钾含量,增加了大于0.25 mm粒径土壤水稳定性团聚体含量,降低了土壤团聚体破坏率,提高冰糖橙果实产量,同时改善果实品质,与固体有机肥有类似的效果。综合考虑肥料成本、土壤改善效果以及对冰糖橙的叶片养分状况和果实品质的影响,液体有机肥在冰糖橙栽培中可以作为固体有机肥的一种短期替代或作追肥使用。This experiment investigated the effects of liquid organic fertilizers on the soil fertility and fruit quality of Bingtang orange(Citrus sinensis).The results showed that liquid organic fertilizer had a positive effect on soil fertility and fruit quality compared with the control group(CK).The samples were divided into four treatments based on a base fertilizer of 3 kg of compound fertilizer:no organic fertilizer(CK),solid organic fertilizer(CF),YHY liquid organic fertilizer(T1),and YLG liquid organic fertilizer(T2).The study found that compared with CK,liquid organic fertilizer increased the organic matter,alkali-hydrolyzable nitrogen,available phosphorus,and available potassium in soil,increased the soil water-stable aggregates greater than 0.25 mm in particle size,decreased the rate of soil aggregate destruction,and improved the yield and quality of Bingtang orange fruits.These findings suggested that liquid organic fertilizer could be a viable alternative to solid organic fertilizer.Based on the evaluation of fertilizer cost,soil improvement,leaf nutrient status,and fruit quality of Bingtang orange,it was concluded that liquid organic fertilizer could be used as a short-term alternative or follow-up to solid organic fertilizer in the cultivation of Bingtang orange.
