摘　　要：物候是良种沙棘引进后需要首先观测的重要项目,是分析引种成败的关键因素,也是据以组织配套生产措施的主要参考依据。沙棘良种扦插苗在我国"三北"不同区域引种栽植后,物候期观测的主要项目包括萌动期、展叶期、新梢生长期、开花期、果实成熟期、叶变色期和落叶期。物候观测要细致、耐心,特别是记准物候始期。The observation of seabuckthorn phenophase （SP） is not only the important item after seabuckthorn introduction, but the key factor for analyzing the success or failure of the introduction, and the main reference flame for organizing and arranging the practice in the field. The observation of SP after planting of the seedlings in the field mainly includes the sprouted phase, frondesce phase, shoot growth phase, bloom phase, fructescence, leaf coloring phase and leaf abscission phase. The observation of SP, especially the beginning stage of the phenophase, must be observed and recorded carefully with more patience.
