本文主要研究内容
作者康晨煊（2019）在《设施条件下冬枣品质特性研究》一文中研究指出：冬枣(Ziziphus jujuba‘Dongzao’)是我国商品性最好、栽培面积最大的鲜食枣品种,先进的栽培模式,优良的果实品质,较长的货架期,对于鲜食枣产业的发展至关重要。因此本试验以5~7年生冬枣为材料,采用田间调查和室内测试的方法,研究不同设施栽培(温棚、棉被冷棚、双膜冷棚、普通冷棚、露地),不同采收期(白熟期、初红期、半红期),以及不同保鲜方式(装袋开口、装袋封口、未装袋)对冬枣果实外观品质和营养品质的影响。主要结果如下:1、设施栽培对冬枣果实品质的影响。与露地冬枣相比,设施冬枣大小均匀,一致性好。设施冬枣的含水量高,果实硬度小,脆度比高,口感较好。同时设施枣果的可溶性固形物、总糖含量及糖酸比也均显著高于露地栽培,对总酚及总黄酮含量的积累也有促进作用。通过主成分分析法对5种栽培模式下冬枣果实品质进行综合评价发现,温棚冬枣果实的综合品质最好。2、采收期对冬枣果实品质的影响。不同设施冬枣的果实品质在白熟期、初红期及半红期3个时期变化趋势相近。在采收当天,白熟期枣果的品质较差,随着贮藏时间的延长,枣果的质地下降缓慢,外观品质保持在较为良好的状态,贮藏性好。初红期枣果在采收当天时,其外观品质与营养品质接近半红期枣果的品质,但贮藏性较白熟期枣果稍差一些。半红期采收的冬枣,果实色泽鲜艳,大小均匀,可溶性固形物、总糖等营养成分高,食用品质最佳。但半红期枣果在贮藏期间色泽较暗,果实皱缩严重,营养品质下降迅速,贮藏性较差。3、保鲜方式对果实品质的影响。在常温条件下,装袋保鲜的枣果品质明显优于未装袋保鲜的枣果。装袋保鲜枣果的单果重下降缓慢,维持了枣果的硬度和脆度,还有效地抑制枣果果皮在贮藏过程中亮度降低,使枣果色泽鲜艳;同时装袋保鲜的冬枣总糖、糖酸比、总酚总黄酮等营养物质下降缓慢,枣果的维生素C和可溶性固形物含量的显著增加。其中装袋开口保鲜因透气性强,在常温条件下,冬枣果实失水现象较弱,果实酥脆,营养品质较高,更有利于枣果在常温贮藏。本研究评估了鲜食枣产区生产过程中适宜的栽培管理模式、采收成熟度及保鲜方式,为指导设施鲜食枣标准化的产业发展提供了方向。
