摘　　要：为提高蓝莓果实品质,延长采后贮藏期,以蓝莓品种奥尼尔为试验材料,研究不同浓度无机钙和有机螯合钙对蓝莓果实贮藏品质的影响,明确蓝莓叶面喷施钙肥的种类、浓度及时期。结果表明,幼果期+转色期+成熟期叶面喷钙处理,果实成熟时硬度最大、可溶性固形物含量最高。相比对照(喷施清水),不同钙处理均增加了果实单果重,降低采后失重率。采后贮藏8 d,0.9 g/L EDTA螯合钙处理的蓝莓果实硬度显著高于对照,0.3 g/L氨基酸螯合钙处理的蓝莓果实花青素含量最高。幼果期+转色期+成熟期叶面喷钙有利于蓝莓贮藏,有机螯合钙对蓝莓内在品质的提高效果优于无机钙。In order to enhance the quality of blueberry fruit and extend the postharvest storage period,the blueberry variety O'Neill was utilized as the experimental material to investigate the impact of different concentrations of inorganic calcium and organic chelated calcium on the storage quality of blueberry fruit.And the type,concentration,and timing for applying calcium fertilizer on the surface of blueberry leaves were determined.The results showed that the fruit had the highest hardness and the highest soluble solid content when it was ripe by foliar spraying calcium at the young fruit stage + color turning stage + maturity stage.Compared with the control(spraying water),different calcium treatments increased fruit weight per fruit and reduced the postharvest weight loss ratio.After 8days of postharvest storage,the hardness of blueberry fruits treated with 0.9 g/L EDTA chelated calcium was significantly higher than that of control,and the anthocyanin content of blueberry fruits treated with 0.3 g/L amino acid chelated calcium was the highest.Foliar spraying calcium at the young fruit stage,color turning stage and maturity stage was beneficial to the storage of blueberries.Organic chelated calcium was better than inorganic calcium in improving the internal quality of blueberries.
