摘　　要：以紫红龙火龙果外观色泽为标准,判断其采收成熟度,观察常温和冷库贮藏开始腐烂时间、腐烂率的变化,比较贮藏期内可溶性固形物、总糖、可滴定酸、Vc含量的变化,确定其适宜采收期.结果表明：成熟度Ⅰ、Ⅱ采收的果实在常温下贮藏比成熟度Ⅲ采收的果实延长2d,冷库贮藏延长9～10d.常温贮藏10d后,成熟度Ⅱ的品质最佳;低温贮藏至果实出现腐烂,成熟度Ⅱ的品质略优于成熟Ⅰ和Ⅲ,因此成熟度Ⅱ为紫红龙火龙果最适宜采收期.Taking the appearance color as standard, the harvest maturity of dragon fruit was judged. By observing the time of putresce and the change of decay rate of dragon fruit stored in normal temperature and cold storage, and comparing the content change of soluble solid, total sugar, titratable acid and Vc, the suitable harvest stage of dragon fruit was determined. The results showed that the storage time of maturity Ⅰ , Ⅱ harvest fruit prolonged 2 days than maturity Ⅲ harvest fruit stored in normal temperature, and prolonged 9-10 days in cold storage. The quality of maturity Ⅱ harvest fruit was the best after stored 10 days in normal temperature, while the fruit putresce, the quality of maturity Ⅱ harvest fruit was better than maturity I ,Ⅱ harvest fruit stored in cold storage. Maturity Ⅱ was the suitable harvest stage of dragon fruit.
