摘　　要：以‘冬枣’为研究对象,记录了设施栽培模式下花发育的物候期,追踪了花发育和泌蜜过程,评估了泌蜜量及其糖含量。结果表明:与露地栽培模式相比,设施栽培模式下枣花萌芽期大幅度提前,单花开放时间和盛花期时间均延长,花蜜量更大,花蜜糖含量更高。总体来看,‘冬枣’在设施栽培模式下的物候期、花发育、花蜜含量和成分等表现均优于露地栽培。In this study,by using Ziziphus jujuba‘Dongzao’as a model,the phenological phases of flower development were documented,the process of flower development and nectar secretion was tracked,and the quantity and sugar content of the nectar were assessed under the facility cultivation.The results showed that compared to the open field cultivation,facility cultivation significantly advanced the sprouting stage of jujube floral bud,extended the duration of individual flower blooming and peak flowering periods,and increased both the quantity and sugar content of nectar.Overall,under the facility cultivation,‘Dongzao’exhibited superior in phenological phases,flower development,as well as nectar composition and quantity,compared to those under the traditional open field cultivation.
