摘　　要：以‘金冠’苹果为试材,研究了喷施不同钙肥的苹果在聚乙烯保鲜膜包装(MAP)、果蜡涂膜、壳聚糖涂膜等不同贮藏条件下果实贮藏品质的变化。结果表明:‘金冠’苹果在不同贮藏方式下,随贮藏时间的延长,果实的腐烂、失重、硬度降低,可溶性固形物、可滴定酸含量的下降程度均有一定的延缓效果,同时抑制了维生素C的降解。适宜的贮藏处理对苹果果实具有良好的保鲜作用,其中1%浓度的壳聚糖处理效果最好。Taking Malus pumila Mill.cv.＇Jinguan＇as test material,the storage quality of the apples under the different storage conditions of plastic membrane atmosphere storage（MAP）,fruit wax coating,chitosan treatment with different calcium fertilizers were studied.The results showed that different storage modes inhibited the fruit rotting and weight loss,delayed the decrease of fruit firmness and titratable acid content,reduced the soluble solid content,inhibited the degradation of vitamin C.The suitable treatment had good effect on preservation of apple fruits,in which 1% chitosan treatment had the best effect.
