摘　　要：研究生长期不同肥料处理对冬枣果实贮期各项品质变化的影响。处理在冬枣盛花期至幼果发育期进行,分别为氨基酸肥、稀土肥和矿物质肥,以常规管理为对照。冬枣样品在花后110d采集,分别在贮藏0～105d的6个时段进行品质分析。结果表明,不同肥料处理冬枣在贮藏当天,果实成熟度和总糖含量高于对照,其他指标与对照差异不明显;贮藏期间,各处理果实的转红、变软及腐烂等现象早于对照出现,氨基酸肥对提高冬枣果实贮藏期间总糖含量效果最显著,其次为矿物质肥和稀土肥,矿物质肥处理对提高冬枣果实贮藏期间VC含量效果最显著,各处理对冬枣总酸含量和果实硬度的影响不显著。采前肥料处理不同程度地提高了冬枣的果实品质,但给果实的贮藏带来了负面影响。In this study,the effects of different fertilizer treatments during growth period on storage quality of Dongzao jujube were investigated.Three kinds of fertilizers（amino acid fertilizer,mineral fertilizer and rare earth fertilizer） were used to treat Dongzao jujube during the development periods from blooms to young fruits.Dongzao jujube trees submitted to normal management were used as the control.All fruits were harvested after 110 days of blooms and the samples were analyzed at six different stages during 105 days of storage.The results showed that the mature degree and the total sugar content of treated fruits were higher than those of the control.During storage,all treated fruits exhibited an earlier stage for turning red,weak and rot than that of the control fruits.A significant increase of total sugar content in amino acid fertilizer treated fruits during the whole storage period was observed,followed by the treatment of mineral fertilizer,rare earth fertilizer and the control.Mineral fertilizer could obviously increase the content of vitamin C during storage,but did not result in a significant difference of total acid content and fruit firmness.Therefore,all fertilizer treatments could increase fruit quality of Dongzao jujube in a certain extent,and also result in negative impact during storage.
