The extended position device for raising seedlings of this creation has plural number in the bearing container of matrix-style configuration； Whole extended position device for raising seedlings system is connected with a stretching, extension piece between bearing container adjacent two-by-two respectively, and what, which respectively stretches, to be preset at least on the sheet body of piece together for the guidance stretching, extension piece bending folding part mono- Bend. What is in use, form the space for containing medium and seedling, independent growths in the bearing container for keeping seedling affiliated using each bearing container； When necessary, it can pass through and stretching, extension piece Bend rolled over into curved mode, adjust the distance between adjacent bearing container, make to reach the demand of plant growth visually cultivated, adjusted the purpose of plant shoot growing space in due course.本創作之伸展式育苗裝置，係具有複數呈矩陣方式配置的承接容器；整體伸展式育苗裝置係分別在兩兩相臨的承接容器之間連接有一伸展片，於各伸展片之片體上預設有至少一道供引導伸展片彎折的第一抝折部。於使用時，即可利用各承接容器形成供盛裝介質及種苗的空間，使種苗得以所屬的承接容器中獨立生長；必要時，可透過將伸展片抝折彎曲的方式，調整相鄰承接容器之間的距離，使達到可視所培育之植物生長需求，適時予以調整植物地上部生長空間之目的。
